Window motor noise? Buzzing Passenger window motor was replaced in August. Also did the Auto trix kit which routes the power from the battery directory to the motor. All has been working perfect until today. I tried posting a video but it wouldn't let me.
When the window rolls all the way up and tops out to where it's suppose to stop there is a horrible noise (buzzing noise). The noise only occurs if I hold the switch to bring the window up. Occurs on both driver and passenger door switches. The noise does not happen during the whole upward motion, only when it reaches the top closed position.
Noise is coming from behind the door handle. Which I'm thinking is the motor.
It was going up fine but the more I did it, right at the top it looked like the window wanted to struggle.
Any ideas???

Buzzing comes from relays. It could be expressed in the relays themselves and/or the behavior can be parroted through other components like the thermal switch inside the motor.
The only thing that would have introduced a relay to the passenger side is the kit you installed.

Update: Replaced motor and almost well. Pulled the 6 month dorman motor out and listened to it with power and you could hear a slight grinding sound so I'm thinking the motor was a dud and burned up.
Replacement dorman works fine without noise. Hopefully it lasts. If not I'll try american made.
