Window regulator not working properly?

Hi,

Do you know if it has express closing windows? I ask because some vehicles are equipped with an express closing feature (front windows only). During an express closing, anytime an obstacle is detected in the way of the glass, the motor will stop and reverses travel to avoid pinching an occupant's fingers. Modules in the doors are programmed to compare the position of the glass to the amount of current being used to drive up the glass. The system also includes various features to manage the perceived forces on the glass as it travels up. If the circuit perceives too much resistance, it will reverse the motor.

With that in mind, did the glass move freely up and down by hand prior to finishing the job? If there is any binding, it can cause this to happen.

If the glass is not moving smoothly without binding, verify that the glass run seal is fully and correctly seated in the metal run channel, particularly below the beltline.

If none of the aforementioned information seems like a possibility, then you will need a scan tool that can communicate with the door modules for reprogramming. I attached the directions below for that procedure.

Let me know if this helps.

Take care,

Joe

Is the window fully seated in the track? If it is now down the entire way, it will cause it to lower. Also, if you avoid the express function, are you able to get it to close?

Also, are you able to have the can-bus scanned for codes?

Hi,

At this point, it sounds like the module needs to be reprogrammed. The manual indicates it needs to be done after regulator replacement. This is the only other thing I can think of. The problem is you need a scan tool that can communicate with the module. I attached the directions below.

Let me know if this is something you can do.

Take care,

Joe
