just got the car back from the auto body place for an insurance claim.
And the wipers do not work in any way shape or form there's no power to the fuse from the engine side. They of course that they didn't do anything and the windshield wipers were fine when they were. There's literally no power on the fuse block and I see all the wiring schematics for the other side but where do I look to troubleshoot the power from the battery to the fuse box?
Re: just got the car back from the auto body place for an insurance claim.
If you've got the GM Service Manual for your car, go to the electrical section, and start at the TOC. You're looking for Power Distribution. You'll have a few pages that show the wiring from the battery to the distribution blocks, starter, etc. Then you'll have a series of diagrams that cover the wiring to and from each fuse. If you go to the section on the wipers, in the electrical diagrams, and it should show you most of the circuit, as well as show you flow charts and descriptions of tests you can perform to isolate the issue.

what year ? you used volt meter and made sure you put the ground lead on a good ground ? or you used a test light ?
body shop work why ? where ?
<sarcasam>Yes, I meant to WHOLE FUSE BLOCK..</sarcasm> If you read my original post correctly I said there was no power ON the fuse block, implying only that particular fuse. No offense, but if you're not going to offer helpful suggestions, like other members here, I'd appreciate you not particapting. And of course I used a voltmeter.

Does the radio work (if it is stock)? Can see the reason in the wiring diagram. The radio and wiper share the same feed at the fuse block.
Starting from the upper left, the red wire is fed from fusible link B. That is connected to the starter solenoid. A little to the right and connector C100 is the large bulkhead connector by the brake booster.
From there that power link goes to a bunch of places, so I doubt that is the issue.

how did you drive it with no power to the fuse block..? fuse link powers the ignition switch then sends battery volts to the distributor coil and other components .. they may have damaged the wiper motor ..blew a fuse or ? ..use a jumper fused wire see if the wiper works .
most likely a wiper fuse blew also .because of your odd ball comments on what you checked out ...LOL..

please stop trying to harass me on this forum, or I will complain to the management. Your posts are not helpful at all in any way shape or form so please stop there now. I have already explained what I meant by that

What sort of damage had to be repaired, and what did they do to repair it?
They replace the entire front fasha because someone had backed into the car over by The battery area
Re: just got the car back from the auto body place for an insurance claim.
hello again gentleman thank you all for the help so far. I'm trying to figure out where the relays are on the starter solenoid and what they look like.
Re: just got the car back from the auto body place for an insurance claim.
since he stated he is a simpleton and a non mechanical person what he did before this issue was , he replaced the lock cylinder . now that could have messed up the ignition switch contacts.

I've had quite enough of you. I'll be complaining to the admins of the site regarding your comments, I did not change the lock cylinder
Re: just got the car back from the auto body place for an insurance claim.
So. I finally revisited the wiper issue (ya, I'm tired of them not working). I used the meter to try to find the issue and ihave a couple of mysteries and I'm hoping you guys can help me figure out.. 1. The fuse block only has one (dead) wire connectef (see pic. It's the white wire). And while I was chasing things out I noticed that some other wires were in this plug but I don't know where the plug goes. Do you know where it plugs in? (See the other pic) . basically, if I can figure out where that plug goes and figure out which wire is hot to the motor and I can rig another accessory power to it.
UPDATE: Ok through searching the forums, I've figured out that the white (dead) wire powers the whole system.. a lesser question would by WHY it died, but I'm not extremely worried about that...what I AM worried about is what goes on the other side of that fused white wire..???
Re: just got the car back from the auto body place for an insurance claim.
The white wire is power out of the fuse block to the wiper system. If it's dead, check the fuse. If the fuse is OK then you need to get the power distribution wiring diagram for your car, and follow the trail until you find the break in the system.
So does your radio fuse have power? If so, look at the wiper fuse again. If not, you might want to look at that brown wire from the ignition switch. Or the red wire at C2 on the ignition switch, or check the red wire feeding the Pwr Acc circuit breaker for power... If any of this doesn't make sense to you, you probably need to pick up a service manual and start reading, or hire someone who understand auto electric.
The other plug sure looks like a switch connector. Without the wire colors, it'd be hard to guess, but maybe the foglight switch, or rear defroster, most likely not the problem with the wipers.
Re: just got the car back from the auto body place for an insurance claim.
cool. thanks for solving the mystery with the plug as for the break in the system, don't you think the lack of a wire one side of the fuse block would be the problem??
Re: just got the car back from the auto body place for an insurance claim.
No, because the fuse block uses bus terminals. If you look at the diagram or the fuse block, the brass terminals are connected across several fuses. The same wire feeds power to the radio and wiper fuses. The hot side of the fuse terminals for both those terminals is one piece of brass with one wire coming in powering both. The fuses split the circuit off to two fused circuits, one for the radio and one for the wipers, so that if one fuse gets shorted you only lose one of the circuits instead of both.
Re: just got the car back from the auto body place for an insurance claim.
Well nuts, there's power going out of the fuse block but the motor isn't working. another motor does work because they tested it long ago now I need to figure out what's broken in between the connections
UPDATE: i have verified powerout of the fuse block, however I'm having trouble chasing it from the fuse block out into where the engine block is. Can't seem to find the right wires
