Looking for some electrical help. The data out there currently is incomplete and suspect at best.

Here is where I'm at

I'm close, but I'm not getting any type of speed control, other than low and high and no park. But I can make park work, just not when wired, so I've got something odd. But the brown wire ( pin 5) as seen get's pretty angry if you give it something it doesn't want

But I've got the wiring mapped out, now just need to figure out what I've got wrong. I don't see any variable capability on this motor, so it's either low, high or omg make it stop (when connecting both the low + and high - together!

Also I can move to mist, and get the wipers to move, it's a quick and easy way to park (without a washer pump, it's fine, with a washer pump that is not ideal )

Any electrical experts want to drop their opinions?

And what I have matches pretty well with a nissan wiring schematic I got online. 1(nada) 2 Green/Red 3 Green/Black 4 Green 5 Orange 6 Blk.. Green/blk Green/Red are the low high, Orange is the park, Green is the 12v and blk ground, so this is really close to what I'm seeing (my brown wire, is in the factory orange location, so it makes sense), but I'm not giving it what it wants (it's not connected to anything). Thought about putting the stock green wire to the nissan orange/brn wire, but if the green is showing 12v the entire time, but the brown wire shows gnd when parked, that is a popped fuse waiting to happen. It's also possible I should be using the yellow wires somehow, but they show dead, so not entirely sure how or where to hook those up.

I've not found a stock wire that does anything different based on position ( but of course not, stock wiring has no idea what's connected to it). So the nissan wiper motor has the configuration currently wired and as I said, I have no intermittent/variable speed, just low, high and no park. The unused brn wire in the Nissan harness shows lots of changes based on position, so that is def the park, internal switch of the wiper motor. But I'm a bit worried about giving it 12v when it seems to go to grn at home/park position. (I've not popped any fuses in my testing, but there is something I'm missing and want to figure it out, so sending this to a few places to see if we can get to the bottom of it and give folks a cleaner guide on how to wire diff motors to stock wiring.

Also if I take pin 4 (currently wired to the green factory wire) and power it, I can touch the hi or low with the brown wire and they will park. so park works, but I've got something not quite right , must have a wire switched, but what does brown, pin 5 hook to, seems it should be an internal switch and no something happening outside the wiper motor.

 

More information, what I thought would pop a fuse does not. I wired the brown wire to the green wire (pin 5) instead and still had low/high but high would pause every time it got home/parked but no fuse blown and obviously don't want the wiper to attempt to park each time it hits home, so some progress, figured I would pop a fuse.

But really I'm still dealing with 4 wires for the motor with really only 3 wires from the car...... That I have to figure out.

Brown to low will park it, then blow the fuse because it goes from 12v to gnd, while the car is still giving the low +12v, 25 amp fuse go snap first fuse, so not bad!! But looking at the wiring possibilities just not sure how I can make it happen.

Something else I just read cites that the Nissan motor may be ground driven, always power and it's expecting grounds to enable the various speeds, so this may just be doomed, however it's working, low and high. If I just knew what to do with the park wire.. Meh.. packed it all up, see if someone has an idea and or I'll look for a different motor, but I've got wipers again and it's much cleaner than the factory big motor. I'm missing something, just not sure what and again, dealing with a 5 wire motor with really a 3 wire car system (ignoring the pink / yellow).

 

This thread has a lot of good information. A few people have got the motor to work, let's hope they chime in. I've got a Nissan wiper motor waiting to go in, I just need help wiring it up.

Those of you that made it work, please chime in and help us out.

Cheers, Ryan

 

I don't know if this is helpful to you or not , but I'll relate a past experience I had with first gen Firebird wipers ;

A friend has a first gen Firebird that came back from a full restoration with dead wipers (they worked before the restoration) . He had the restoration people look at it who noted that the wiper motor was receiving +12V but had no signs of life so they replaced the wiper motor , only to have the same issue with the new motor , no action even with +12V present . Being a lifelong electronic hobbyist I was asked to look at it , and come to find out the first gen Firebird wipers are ground switched , the motor gets +12V all the time and the switching of the ground wires is what determines what speed the wiper motor runs at . My troubleshooting led me to the wiper switch which would allow the wiper to run when I ran a separate ground wire to the metal body of the switch . Come to find out the reason for the failure was that the metal dash hole where the wiper switch mounts had been painted when the car was being restored and the switch wasn't making electrical contact through the paint to the grounded metal dashboard . My friend was nothing short of amazed when I took a small half round file to the hole where the switch mounts and lo and behold the wipers now worked properly , with the switch now making good electrical contact to the dash .

My reason for this post is to reinforce that there are wipers who are ground switched , I don't know if your Nissan unit is that way or not , but there are examples of such ground switching , the first gen Firebird being one such example

 

PS , something I just thought of that also may help you ;

In my opinion , the best way to do what your trying to do would be to obtain the schematic diagram of both sets of wipers , the Firebird and the Nissan , and post them here , so that the two different systems can be compared and eventually wired together . Note that I said schematic diagram and not just wiring diagram , most wiring diagrams show only the external wiring interconnecting the switch and motor whereas a schematic diagram will show the circuit with all of the functional components illustrated , right down to each and every last internal switched contact of the switch and all internal connections/functions of the motor (this being what we really need to do this right) . Naturally I assume your going to want to use the Firebird's original wiper switch which of course will be different than the Nissan's , It's this difference that must be accommodated for and having the schematic for both sets of wipers will allow for the wiring to be done once , done right , with none of the risk to fuses (and wires) that exists while playing "Wire Roulette"

 

I found this schematic for the nissan wiper motor.

Hopefully somebody can make some sense of this.

 

why install a Nissan wiper motor into a 3G ?

 

It's smaller.

 

I looked at your diagram , and I'm now convinced this will not be a very easy swap .

I see a separate relay for the motor , and also a separate "time control unit" as well . I now believe you'd need the wiper wiring harness from the donor car complete with the relay and time control unit to make this work properly . The switch itself doesn't look all that complex , but without all of the other circuit components (and wiring) needed I'm not optimistic of the chances for success here . (We'd also still need the diagram for the third gen wiper switch)

Can you get the rest of the parts from the Nissan ?

 

I don't know about getting the rest of the parts from the Nissan.

Some others have gotten this to work, I wish they would chime in.

 

There is a video at the bottom of this thread that might be helpful in getting it to work. Let me know if it helps.

I can't imagine why a wiper motor from a completely different car made in a completely different country wouldn't just bolt in and work. Sorry, I don't mean to be a dick, but this is far enough out there in the weeds that if you can't figure it out, you probably shouldn't be doing it rather than asking for help.

Maybe try asking someone who's made it work? Like find their contact info and ask them directly? Seems like the chances of someone who's done it finding this thread are slim to none.

 

Give me both years of cars. Model of Nissan and I will get you schematics for both from my Alldata and Mitchell accounts.

 

I think I got the wiper motor from an 89 Maxima and my car is a 1987 T/A.

 

The trans am had 2 diagrams, one for a standard 2 speed motor and one for I presume a pulse motor.

 

Sorry I only had access to my phone.

 

Thanks for the diagrams. Any ideas on wiring this up? I have the pulse motor.

 

Sure, sorta. You're trying to use the Firebird switch, and the Nissan motor. So you need to figure out if the Firebird switch comes close to matching the function of the Nissan switch, or if the motors come close to matching. Right off the bat, the Firebird uses the washer motor integral to the wiper motor assembly, so you'll need an external washer pump motor, and will need to split the wiring off for that. But you'll still need the wiring to the motor to run the wipers while the washers run. And you need to determine if the donor motor has a built in park relay like the Firebird motor, or if you need an external relay. Then you need more than the diagrams, because the diagrams only show you the wiring, they don't show you how the inside of the electro-mechanical wiper motor works. You can't tell from the diagram how that "time control unit" works or what it does exactly, or if you need it to function in a Firebird.

The short answer is you need to know exactly how the Nissan system works, beyond the wiring, to see if it'll even work in the Firebird. A full working knowledge of both systems would be helpful, and the wiring alone doesn't give you that.

 

Ok, so case in point... Let's assume that the Nissan motor has all the features built in that you need, so it can stand alone without the extra gizmos.




We can't tell from the diagram what the behavior of the INT input is, just that it's coming from the switch, which is coming from the relay, which is supplied by the Blu/Yel under certain conditions determined by the relay and the timing unit. And the Blu/Yel? Well it goes to that mysterious electro-mechanical gizmo with a non-standard symbol. There's no way of knowing how that gizmo works from this diagram, or how the timing circuit works.

See what I mean about needing more working knowledge than the diagram can give?

 

Look up the Detroit Speed iroc thread, I can't recall what wiper motor they went with but it's worth a look.

 

I have looked at both schematics and yes indeed you will need access to a donor Nissan to make this work properly . If you look closely at both wiper switches you'll see that both the Third Gen pulse system which you say you have and the Nissan have the same 3 positions from off , and have the same number of contact sets , although the wiring connections to those contact sets are different . An experienced electronic hobbyist should be able to rewire the Third Gen switch to match the Nissan switch , that would be step one , but step two will have to be wiring in the Nissan wiper relay and time control unit , the Nissan motor will need those external components that our Third Gen motor has built in internally .

If your wipers are ever gonna run the various speeds , do the delay function , and actually park themselves when switched off your gonna have to provide that motor with all of it's factory components as wired in the schematic and get someone handy with a soldering iron to rewire your third gen switch , anything less and I have no predictions of success for you ......

 

I don't understand the need. My 86 factory pulse wipers work fine with the updated motor cover. Sure they aren't easy to find but it's also usually possible to repair them (capacitors) and in the mean time you can still use the slow and fast speeds..... it is also possible to wire in the later motors without integrated pumps. Lastly - an 89 Maxima part isn't going to be any more available than a third gen part. Quite the opposite I'm afraid.

There's just virtually no reason I can see for doing this. Though this is only my opinion.

GD

 

It gives clearance to tall valve covers and supercharger for folks that have done LS engine swaps. I think UR5L0 started the idea here, but he only had low speed wiper function just in case he got caught in rain by accident or needed to clear the window.

 

Rainx is a lot easier to deal with than adapting a smaller motor.

 

Trying to find the relay and wiper control module. If anybody knows where to get one or if one from a different nissan is the same, let me know.

 

Try Rock Auto, Advance Auto, or maybe ask on a Nissan forum. Realistically what are the chances anyone on thirdgen.org will know about parts interchange on a Nissan? Know what I mean?

 

Oh hey look I can be slightly useful for a minute.

B8510-07F85 - RELAY ASSY - INTERMITTENT WIPER (interchanges also with a 1983-1988 200sx)

28510-39E10 - AMP - INTERMITTENT WIPER (1984-1989 maxima only)

Both of those part numbers are long long long long long long long looooooooooong gone as far as trying to get a new OE one. Just FYI.


With that being said, I couldn't in any way encourage the use of a Nissan wiper motor(at least one that old) because unless its a Z car then you'll most likely have a nightmare trying to find replacement parts, given that you were even able to find the parts to make it work in the first place. There's a very good reason you don't see 80's Nissans on the road anymore, or even 90's ...or that many 2000's models either... "cough"

I'll help with more info upon request, if I can.. The parts catalogue and any Nissan shop manual type stuff I have access to for something that old is 9/10 useless garbage anyways.


Quite low I imagine, but some people do still manage to get struck by lightning. Lol.

 

does anyone happen to have a little more info on what needs to happen with the wiper arm to motor. Just trying to figure out what was done witlh linkage before i got and buy one.
