I just replaced the passenger side window motor. The motor will only raise the window, not lower it. I pulled it back apart, and it does the same thing freewheeling?

I used my meter on both sides of the plug that attaches to the motor and both show 11mv when the up and down are pushed?

I plugged the motor back in, used a test light and again, Power with Up and Down, yet the motor only turns in the up position? The regulator is not in a bind either.

And yes, I returned the first motor (thinking it was bad) and the second does the same thing?

Also, doesn’t matter if you use the driver’s side switch or pass side...

 

TTT!

Any ideas?

 

Isn't there a relay or a control module that handles lowering the window due to the "express down" feature? Maybe it failed? Sorry I can't be more helpful, I havent seen inside my door.

Humm, Interesting thanks. But the part that throws me is both the up and down pin have power...

 

Well I now know the motor is good.

Again, the plug has power on both pins, and neither switch will make it go down, just up.

I need help

 

Shouldn't down be reverse polarity compared to up? What I mean is that up is (+ -) and down is (- +) I'm not sure, just guessing. It would be nice if someone that has actaully worked on their windows would chime in here.

Ya, you'd think on a Computer Car board someone would know Windows...
