'85 pickup electrical problems. - Pirate4x4.Com : 4x4 and Off-Road Forum

I have an 1985 Chevy pickup with some weird electrical gremlins. I'm a newb to Chevy's but not gremlins...

I got the truck as is and none of the stuff worked then either.

Problems:
No headlights - but the running lights and turn/stop lights work.
No heater/fan.
Wipers barely move.
Power windows don't do jack either.
I'm sure some of the other power items don't work -- but I just need the lights and heater for now.

I have checked the fuses under the dash -- nothing obviously blown. I pulled of the big self resetting fuses for the headlights and heater fan and banged them around, clean off the connections and put them back, even switched them around. No change. Truck starts and runs, drives ans stops...

So what am I missing?

You check the bulds and blower motor ? How bout the grounds ? Do you have 12 volts going to them?

head lights have there own ground that goes from the light to the core support.

besure the power window realy is grounded, mine wasnt and that was the main reason the p/o got rid of it " jacked elec system"

swap out the wiper switch, the super cool factory 75' variable switch i have sucks. swaped it out and everything was fine.

On the power windows, make sure they aren't just so crapped up they won't roll up or down. I had to take the door panels off, clean up the rails, or whatever they are called that windows go up and down on. They were caked with just crap that had built up so they wouldn't let the window move at all. After that they worked fine.
