Just wondering if anyone's done this and noticed a washer improvement! I'm on my 3rd washer pump, none of 'em can suck water right away. Consequently, the motor burns out the center of the impeller after a while... and I'm out buying a new pump. I saw the thing in a junkyard over the weekend, and am thinking of going back for it. But if the performance is worse, forget it!

There was a TSB for that, don't remember if your car was covered though.

 

My car had the rear wiper, which had its own washer pump (from the same tank). The pump on the front wiper motor didn't work, and the rear wiper motor didn't work, so I took the supply hose, routed it to the rear washer pump, and put the front washer line on the outlet of the rear washer pump. It's still hooked to the rear wiper switch, but it works just fine. Stays primed, no problems with it.

That rear washer pump looks identical to the universal replacements you see at the parts store.

I'm interested in this too. my pump is not working again.

anyone know which wire to use from the harness going into the wiper motor that I can cut and route to the in-tank pump?

thanks.

 

take the two wires from the pump on the firewall and check them for positive and negative. once you know which wire is which, run them to the red and blue wires on the washer pump on the tank. i did it in about 15 minutes and ran some wire loom over it to make it look stock.

 

I did this a few weeks ago. Swapped wiper unit from 89 bird to an 86 TA. I swapped everything from the 89 over and it works great. Mostly color coded as well. You can probably just pull the tank w/ motor attached, run the red and blue wires to it, then reroute the hose and you're good to go. Works much better.

 

there is a four-wire harness going into the firewall. which two wires do i use?

 

whichever two plug into the washer pump. the others go to the wiper motor.

 

mine must be different, cuz they all plug into the same place.

 

Take a look again, for cars from 1984 to 1990 there's a connector that plugs into the wiper motor cover, and another one that plugs in to the pump.

 

Hey TomP,

I had this problem not too long after I bought my car (1983). for my case if I would route the washer tube so that it had slack up by the washer motor then there would be a "dip" in the hose between the washer motor and the master cylinder. This appears to keep the fluid from draining back into the reservoir
and thus keeps my pump "primed". Mine is still squirting right away.


it is worth a try.

 

Yeah, there should be a long 5 plug harness on the top, then on the very bottom of the metal cylinder it has a blue and red wire for the pump.

 

my car must be some kind of bastard, but i looked again:

the two wires going to the bottom of the motor supply the motor. i unplugged it and the wipers did not move when activated. they are red and yellow. so they definately control the motor.

so, it must be the harness that goes into the plastic cover. the colors are red, yellow, green, and gray.

the wiper pump plugs into the bottom of this plastic cover and there are two prongs on it that plug in.

 

I'm fairly certain (95% sure) that my wires were blue and red on my 86 TA, same as on my 89. I wired it straight up and it worked right away. Thats odd thats yours are different. I seem to recall (not too sure) that the yellow wire wasn't even used when converting to 89 firebird washer setup.

 

Ugh, you're right. The pump takes its power from the cover. :P

 

soooo... can i tap into any of the wires or are we talking about taking off the cover and soldering into where the pump plugs into? anyone know?

 

ok i thought about it and came up with the following solution:

step 1:
take out original motor.
remove both ends.
throw away the guts.
free the ends of the terminals on the inside by pushing away the copper area.
slide on a female connector (may have to widen a bit manually - not exact fit)
crimp wire and run through motor housing then water tube (requires careful small drilling to widen one of the holes)

at this point looks like:

 

put it all back togethor and now looks like:

 

now, just slide that into original place, and run the two wires to your new pump (inside the tank design).

after routing the wires and hoses, and using a shroud for the wires you wouldnt even notice it had been modified without further inspection.

and, it works GREAT. IMHO much better design.

 

does anyone know what type would have come stock on the 92 camaro B4C? the guy that had the car before me took out all the windshield washer stuff to save weight when racing , i see the motor on the firewall with the metal cylinder coming from the bottom but i didnt know if that was the washer pump or part of the motor? also can anyone send me a pic of how the whole thing is routed since i have no plumbing or anything for it yet and im not even sure what type of hose to buy to plumb it
any help would be appreciated
thanks

 

the washer pump looks like the pic above and pops out the bottom easily.
the motor much larger and is attached to the whole assembly.

 

>>Thank you for posting this, I am looking into upgrading my system for my 85 to the later model in-tank Electric pump style. Is the new style an all Electric pump or does it use vacuum as well. I'm looking to elimanate vacuum lines with something that is a bolt in application. I am looking to put a new system in- not used. Thank you in advance for any further advice.
