stupid power windows

[halfnhalf325]

ok probelm dont knwo if its big or anything but the left side windows in my car will not roll down front or back its killing me. just wondering if you guys have any ideas as to what this is and how to fix it.

Have you checked the fuses?

I'm not sure if the left side windows are on a different fuse than the right side windows, but it is worth checking. If it isn't the fuse, the next two things I would check are: 1) the switches for the windows, 2) and the window motors.
Hope you easily find the problem. Good luck!

Agree completely, you might need an electrical diagram though to check the switches.

how do you check the switches someone told me to sand down the connectors on the switches, but i dont anything about the motors.

Well first check the fuse, then the wiring and motor. The wiring and motor could be done at once, you need to take off the door panel and locate the motor. The wire connecting to the motor shuld be the switch wire, im not sure you would need to check in the electirical diagram. The way the switch works is when you press the switch, you are completeing the circuit so at the end of the wire connecting to the motor, there shuld be an eletrical current from pushing down the switch. Check this with a voltage meter, if it dosent work then you need to get to the end of the wire connected to the switch. You need to some how get to the wire attatched to the switch, I havent seen the switch on that car so im not sure how to get to it. Then you need to take that meter again and toutch both ends of the wire, the meter shuld show a current going through, if it dosent then there is some problem with the wiring. If a current does go through when connecting the ends of the wire then there is a problem with the switch. Back to the motor, if when you push down the switch and there is a current then there is probably a problem with the motor.

If you dont know mutch about wiring and how to take panels off the car then I wouldent suggest doing this yourself.

If you have any questions about what I said above or if I didnt explain something clearly feel free to ask.

 

[halfnhalf325]

well its not the fuse, and my mechanic said he checked everything last time and to just look at the switches whats the best way to clean the connectors, he said sanding do you guys agree?

 

[coyotefreek]

That might work, but that wouldent explain why both left windows arent working. If you do sand it then make sure to use an extremely fine grit like a 600.

 

[halfnhalf325]

yea that was the plan, and it is really weird that just that one side stopped but we have seemed to always have problems with the power windows.

At the risk of sounding stupid, did you check the window cut off switch? I did not know what year car you have, but I have accidently activated the cut off in my e30.

 

[halfnhalf325]

i ahve an 86 are you talking the button that locks all the windows, othewise i do not know about a cut off switch.
