Window got stuck all the way at the top. took it apart today intending to replace the roller with one of LRD2&ME's replacement rollers...but the roller is in perfect shape.

when I press the window button I can hear a click up in the dash but no noise comes from the regulator/motor

 

Sounds like motor, but might want to put a volt meter on it. That is if all other windows are working (window control module, rear window isolation switch, etc.).

 

yeah, all the other windows work

 

Disconnect the two-wire motor connector inside the door panel and feed it briefly with a 12v supply (like a battery charger). Flip the wires polarity to check if the motor is ok.

In my case, the symptoms were identical to yours, and the BCU unit under the glove compartment was clicking when I tried to lower the window. This is caused by the overcurrent safety.

One of the 2 wires from the BCU to the door was ground. I ran 2 new wires form the BCU to the connector and solved the problem.

If that's the problem, I can send you the color code to identify the wires to jump.

just checked - it does only click behind the dash when I try that window (up or down). it doesn't for the others.

 

It does click for all windows when they reach the end.

When you try to lower the window, one wire is 0V (ground) and the other has +12v. Polarity is inverted for rising, It is possible that the one carrying the +12v for lowering is damaged and ground somewhere. If that's the case (and it was mine), then he BCU will trip immediately, doing that ''click'' you hear.

Try feeding the motor directly while disconnecting the normal supply wires. It will tell you if it is the motor or the wiring that is faulty.

ahh gotcha. I'll try it next weekend. thanks again.
