Exclamation Replaced window regulator - burning smell!!!

I just replaced my first window regulator. After getting the window in and attached, I wanted to test it before putting it all back together again. I turned on the car, and reattached the rear passenger switch. Pressed the button and the window worked! Wonderfulness ensued! Went back to driver's seat and tried the driver's control of rear passenger window. Window stuttered. Did not roll up or down. Ran around to back of car and bent down to check the window. A strange smell met me. Smelled a little like burning... No smoke to be seen. Just a smell. Sniffed around and it seems to be strongest around the door handle. Looked up there and can't see anything other than a few wires - but no obvious damage. Rear passenger door switch doesn't work either now. Window won't move. Went back to turn off car, and tried the window switch again. Can hear a clicking sound coming from around the glove box area (fuses???). HELP!!!!!!!!!

Open the door up and check your work.

The door is already open and all taken apart. The last step I took was replacing the glass and attaching it to the new regulator, then testing it with the switch. All trim and panels are still unattached...I can see inside everything, but don't see anything wrong...

Recheck your work again.... Obviously something is binding .

The smell is an overloaded motor. Take it all apart and start over again.... Pay attention to every detail ... You have something bound up which is preventing your window from moving freely.

There is an off chance that you may have a defective regulator.

I had wondered about the motor - wouldn't there be a smell emanating from the motor rather than up near the door handle? Is there a way to run power to the window regulator from an external source to test it? Want to eliminate whether it is a faulty regulator or if there is some electrical problem with the car...

The motor is toast. Been there, 2 motors fried up on me like that for no reason the smell is the only indicater and ofcourse the wndow not working, but they where the rear ones and rarlly used. You can power the window motor directly by an outside battery and switch polarity to see if motor moves.
