Common Gorund/ground Bus?

[duncanpath]

anyone know of a shared ground or relay or anything that headlights, blower for interior heat/defrost, and wipers share?

had a strange one the other day when none of the three mentioned systems worked, and then suddenly worked again?!?!

 

got them back by cycling the headlights on/off a bunch.

 

anyone had such strangeness happen to them?

 

front windshield washer fluid spray has quit as well(rear works), but i don't know if it is related. i know headlights and sprayer

share the same swithch/handle area... is that a hint?

 

anyone know where to get awesome elctrical schematics better than haines?

 

thanks

IIRC there are 4 grounds in the cabin, one behind each front kick panel, one in the rear passenger side and one in the center under the console.

 

 

There are 3 in the engine bay, one off the battery, one on the manifold and one on the driver side firewall. (I think, been awhile)

 

 

However, the Blower, AC and Headlamps go off replays on the passenger side of the engine bay near the wiper motor. With the vehicle off, pop the cover to the relays, pull them one at a time and start looking there for anything like rust, corrosion or frayed wires.

 

 

Other more common thing other owners have had on these older vehicles is the stalk or combination switch connectors getting corroded or loose and the headlamps not woorking. Simple clean and fix.

 

 

Wipers go off a fuse under the driver side dash.
