1999 Corolla - New Passenger Front Window Regulator/Motor Stuck

#1
Hello,

I just installed a brand new Passenger Front Window Regulator with Motor. When I tried to check/test it w/o window for the first time:
- I turned ignition
- the regulator automatically (!) started working and went to the top position and it stuck

Now using the control button I hear click but nothing happens - it does not move down. All other windows and power lock on this door work just fine. It feels like an electrical problem or this regulator is faulty.

Any idea how to fix it?

Thank you.
