driver window no power
 

03 H2.

The driver windows motor is getting no power when the switch is pressed. The lock works fine.

It was working, then it would work once in a while. Now it doesn't work at all (no power).

I took apart the switch, I could not see any damaged areas. The button backlight is working.

checked the wiring from the switch to the motor... all good, if i give it 12v it works good.

One possible guess is the window regulator............

I had a similar issue not too long ago. My window would not go up or down. I had power to the switch and it lit up just fine. Took it to the dealer and they reported a bad window regulator (motor). They replaced it and all works fine!!

These can be found on eBay.

it can't be the regular or motor. If i give it power directly to the wires which is coming from the switch, it works. There is no power coming out of the switch.

The question can everything else be working on the switch but one window? could it be the switch itself OR is it the wires coming INTO the switch which are giving problems.

One way to check that to see if its the incoming wires to the switch......

Strip off a tiny piece of insulation off of the incoming wire and do the same to the wire that it mates to on the other side.

Then use a jumper wire with alligator clips on either end and simply clamp them to the exposed wires. If the window operates, then its the switch. If the window still doesn't work, then its not the switch but somewhere else.

The switch itself could also be tested with a meter or test probe. Test leads up inside connector holes with probe and see if light comes on.

that is a good idea. but i am not sure what is the color of the incoming wire for driver window

All you need are the wiring diagrams for the door. I have a copy if you dont. Send me PM with your addy and I can send you the file.

thanks

replaced the switch today, and everything works. switch was the problem.

I sent you the files for the window switch anyway. Glad you were able to get it fixed.:jump:

At least it wasnt the window regulator itself like mine was, the switch would be an easier fix. That was my second guess like I stated in my other post.
