Driver side window won't go down

As the title states, I'm having trouble with the driver's side window. The problem's been intermittent for a few weeks, now it won't go down at all. At first, when I pushed the auto down, it would go down a little then stop, but i could push the button in the down (manual) position and it would work. Now nothing. I can hear the relay behind the knee panel click when I push the button, but I get nothing. I pulled off the door panel to check voltage, and I get 12 volts when I push the up button, but 0volts in the down position whether I push it to down or auto down. I don't have a schematic, so I don't know what all is in the circuit. Any ideas? Thanks

Chris

Sounds like the switch itself is bad if you are seeing 0 volts in the down position only. Put a test light directly on the back of the switch and see if it lights when trying to roll down.

yep, sometimes the contacts will break. replace the switch and you should be ok.

not sure with our trucks but you may be able to get inside and clean up the contacts. I did this on my 96 mustang cobra and worked like a charm.

Ok. I went out and checked the switch with a meter and it looks ok. I used a jumper wire on the plug and I had the same result: relay still clicks but no action. I swapped the relays earlier thinking maybe a bad contact on the relay, but nothing changed. Does anybody have a link to a wiring diagram?

I had the same issue. I was getting voltage, but no go. Voltage doesn't mean much if there is high resistance in the switch. Clean the switch contacts and you should be good to go.

if you have a high resistance your voltage will drop..always basic rules of electricity.. you cant have 12.0V at the motor and have big resistance.. bigger resistance more the voltage drop..

take a jumper wire..one positive on negative..touch the actual motor contacts..you wont hurt it..if it fails to go up or down you need a motor.. if it moves you have wiring or switch problems..

tan with light blue stripe....white with black stripe are your 2 wires..

positive on one and neg on the other will make it go up and switch them it will make it go down.. see if the motor works
