Hey folks. I am hopeful to get a wiring diagram for my 87 PA, including the windshield wipers switch and motor wiring.

I have been gradually fixing up this car as I have time to. It is a very rare 2-door model. So far I've had it painted, fixed a few small electrical problems, charged the A/C, and rebuilt the transmission. The trans was an 'experimental' build. I used 4T65E parts in the 440T4, including all clutches, the pump and pump shaft and more.

Two weeks ago I went on a 1600 mile round trip from Tuscaloosa, AL to Miami for a two weeks training seminar. It ran perfectly, with the exception of the Cruise, and wipers only working on low speed.

I was able to fix the Cruise by cutting out a bad spot in the cable from the switch, which goes down through the column. That was an obvious problem with frayed wiring. It was near the switch end, and there was enough slack to cut the cable back a few inches and re-terminate it to the switch.

The wipers simply stop if placed in High position. There are no visibly corroded connections or anything else which would indicate a problem. I have tried to search AutoZone and they don't have the correct wiring diagrams for these cars. For some reason they only show the older RWD cars.

So, if anyone has this wiring diagram, I would be very thankful for a copy. I tried comparing it to my A-body cars but the wipers system is totally different.

Thanks in advance!
Sincerely,
David

I think I have a late 80's C or H body manual at home. I know I've got one for the '86, but that wiper motor is different. I'll check and see.

Thanks Matt. I appreciate it.

There's no hurry - I was able to fix the wiper motor. The problem was corrosion on the brushes, from sitting. This car sat up for a couple years.

Here's from the 1989 C/H body manual:

Thanks Matt!
