No power to window switches

[ttrreevvoorr]

RESOLUTION:
It was unplugged when I switched out my hood latch lever the other week. I plugged it back in. It fixed my window switches. Check my fuses and replaced #10 and everything else started working



also, this blue/green wire is just hanging down. I see that it is plugged in at it's other end but does not connect to anything. Is this for alarm? ...or?



thanks again for everyone's help on this. i really appreciate everyone being here for me like this.

First thing to do is ground the green/black wire on the starter.

Disconnect it first, of course.

GL!

I think you should let me take a look at it. Tonight?!

window switches
HVAC
Horn
Mirror switches

my e30 had a wire grounding somewhere next to the shift knob..my window switches only worked if i moved the stick all the way to the right so try playing around with the stick as ur messing with the switches

ground by the shift knob? I don't recall seeing this in mine, do you have a late model? I have an eta, not sure if this is different. I'll take a look when I get home, relays as well.

Pull your window breaker out and put a jumper wire in between the two wires it's most likely the breaker I just replaced my g/fs she had the same problem

tried this the other day with no luck

This is perfect.

Use a testlight, not a meter. The testlight will show for a fact that there is power in the circuit, while a testlight only shows voltage. There is a decent one at Wal-Mart for $5, 3M brand, heavier duty than most cheapies.

Remember that only 2 circuits in the whole car run on the "Unloader" relays, thats the HVAC fan and the windows. The starter controls the unloader relays, as bizarre as that sounds. That is what the green/black wire coming off the starter is for, it shuts down the windows and heater fan when the starter is running. EDIT: does your heater fan work properly? if so, the unloader circuit works, perhaps a bad K7(iirc)?

Good luck.

Hey Luke are you suggesting this may be a relay? My HVAC and everything on my speedometer (except MPH) stopped working days after the window switches failed. I'll check the relays and everything and update with my findings.

Yes, this too, that ground point has failed on more than a few E30s

I'd be down for a faulty breaker as well. Check to make sure there is power on both sides of the breaker when it is in the "on" position.

And yes, the breaker can fail.

check the child safety button on the console? Seems simple, but worth a look.
