Power windows not working... UPDATED 7/9/05

For the time being to see if the breaker is your problem. Take a short piece of wire and strip both ends. Slip it into the 2 wire ends and see if your windows work. If they do, then take a pair of pliers and lightly squise the loose plug to make it a tad tighter.

If the breaker switch isn't plugged in your windows won't operate.

So that red thing is the breaker switch? What is that little black button thing on the driver's side?

Would that explain why none of my power accessories work?

Once again you save the day :P I'll check that tomorrow morning.

Red button is the circuit breaker, that will cause the windows and sunroof to not work. Check under the dash on the lower left corner above the footrest is an Accesory panel. It's white and will have multiple plugs plugged into it, Check to make sure the green wire running from the circuit breaker is plugged in. And that the black round connection is plugged in that runs up to the sunroof.

Ask me how I know.
Same if you take out your hazards, your turn singnals won't work.

I did it, hooked up the battery, the windows didn't go up and the light switches didn't light up.

I took the trim off the door and hooked the front window directly up to the car battery and the window went up and down no problem.

DId the same thing for the rear window and it didn't work. I think the rear motors are fried. I hear they are a pain in the ass to fix... comments?

I guess I gotta track down some of these pins to find what is up with the power getting to the window. I did install the E34 535i ECU with my M30 swap... would that have something to do with it?

it shouldn't but, check your starter and do you have both the black/yellow and black/ green wires hooked up together? The black/Green wire must be grounded for the windows to work. I'd get a voltmeter and start checking for voltages.
