window problems

**NavdeepWS6** · 05-18-2009, 09:16 PM

ive been having problems with my passenger side window it goes down but does not come up. i have to wait some time before i try again and it only goes up a little and it take a while for me to get it all the way up. so has anyone else had this problem and how did you fix it

is it a wiring problem or the motor it self

Buy the window motor on ebay. I spent $19.00, and the swap out is reletively easy, just time consuming.

My driver side is starting to go, not looking forward to it!

I installed this wonderful kit to speed up my passenger window motor. Works great!!
You may need a motor and this kit

That looks good, why is it only for passenger side? Besides the switch whats diff between pass and drivers windows? The driver side does not always close all the way for me especially if car is not running, my passenger side I had fixed under my extended warranty 2 yrs ago, it works perfect. I would like to upgrade wiring first, then if necessary replace motor. Thanks.

The passenger motor apparently has a longer wiring path to positive voltage. The longer the wiring, the greater the voltage drops along the way.

Yeppers.

Autotrix makes a kit that solves this problem.

Little known also fact.. the BCM was poorly soldered from the factory, resoldering the joints in the BCM can fix randomly working windows as well. Thought it isnt often. There have been many threads started about it

Thanks for the support guys!!

The passenger window kit can in fact install on the drivers side but our testing has shown no improvement with voltage/physical force/speed. The factory wiring is sufficient for the drivers side; adding relays wont help much at all.

The only bottle neck on the drivers side is the factory express down module. It interrupts the power trunk to the window motor with a solid state board that detects a voltage spike to determine the motors end point- and then returns the voltage to the window motor from another terminal off of the board. Our Drivers side express down module is our own design with a non intrusive hall-effect sensor to detect the end travel voltage spike. It reacts faster and allows for more current to get to the window motor because it is not interrupted by a solid state electronic board. It only takes a split second of touching the down switch to allow tour module to latch, no more holding the switch down for 3 seconds (half way down) before the factory module takes over.
