wiring stuff

Hi all Im looking for the schematics for the horn, and Windshield wipers. Also does anyone know where the grounds are located for both? Horn is still dead and for some reason the wipers decided not to work anymore
Thanx

I don't know where the grounds are supposed to be, but you can try using jumper wires to create a ground to test each part to make sure of the problem. If bad grounds are the culprit, you can always run a new ground wire.

Not sure about the wiper motor, but the horn is a self grounding unit.  Kind of like the temp sensor in the engine block.

 

Well I checked it out and the wiring seems to be fine on the wipers. Just a visual inspection on the motor and it seems fine. Is there an easy way to check this?

just checking my manual.  Do you have the anti theft alarm fitted?  If so the wiper switch ground connector doesn't go directly to the ground terminal mounted on the firewall above the wiper motor.  You should find a multi pin (3) connector that goes into a loom to the passenger side of the ground connector. This multi pin plug has to be plugged into the ground terminal and then your wiper switch ground connector goes into the multi pin.  It would be a lot easie to explain if you had the pic.

As far as the horns go, mine is a '71 and has a horn relay which also operates the horns if you leave the key in the ign and open a door (that part of mine is disconnected cause its a PITA). maybe you have a dud relay?   It looks like they both operate off the same fuse too.

When working around the horn relay do not ground the relay, it will blow the fuseable links connected to the relay.
