all four power windows dont work no 12v to driver switch

[Flatline1121]

so, driving around the other day (rainy) pulled into a gas station and rolled my window down to talk to a buddy.
Rolled the window up, drove to a friends, came out to leave and my windows dont work....


i tried a good amp, switch, swapped the fuse under the hood, and visually inspected all fuses under the dash.

Tested the ground in the plug for the master switch and its good. using that ground, there is no power from any wire in the plug with the key at IGN.

is there something im missing? or do i have to start dissecting the chassis harness to find an issue?

I did search but everything points me to the amp and so on so its not helping much.

New one on me. I would have thought it to be a fuse.

If you don't get an answer can move to the Tech section.

I personally have never seen this go bad, but the windows have an inline circuit breaker that supplies the switches and amp with 12v. It's located beside the SMJ under the dash. It's possible it's gone bad and isn't supplying the ignition relay with the current it switches to the power window system.

thanks for the replies. i figured that since there wasn't 12v to the switch, there had to be a break in the main power wire to the switch.

Whats SMJ? im dumb and should probably know that.

anyway, i started at the fuse checking for 12v on each side. good.

moved to the relay box on the driver side, found my wire (blue/red) and tested. Got 12v.

moved to the giant white plug that unbolts (what connects the wires from the bay to the dash on the driver side) and got no voltage.

had to unbolt my fender from the top, but found that my wire was broken and arc'd to the chassis. (had it tucked up to keep from hitting the wheel) not sure why it didn't blow my fuse, but there was corrosion so maybe that built some resistance and kept the arc from pulling more than 30 amps. weird s***.

the woes of being low.

SMJ is the white box you checked. It probably is tripping the circuit breaker instead of the fuse since your short was in between the two.

Glad you solved it

Before checking all that stuff, an easier thing to test:

- go to the source, i.e. remove the door panels & jump the 2 wires connecting the motor to power/ground. One connection selection windows go up, reverse pos & neg, they go down.

I did this w/ a spare plug I had and just wired it directly to a spare 12v I had lying around.

- if the window doesn't work, it's something w/ your window mechanism. if it does work, you have to start tracing backwards.

QV, that would work if it was only one window. To which I would have started pointing to a bad regulator or motor (seen plenty of both go bad). Since he had 4 go out at once, it's pretty obvious he needed to focus on the lowest common denominator here, IE power routing to the main switch. Plus, from the sounds of his last post, he fixed the issue and they work again.

Like I ever read these posts very carefully

Damn, the vert forum is dead, maybe I have to start posting some sexy build pictures, hee hee.
