2003 mustang gt
I was replacing the door speakers in my 03
Mustang gt and when i finished the driver side
window wouldn't roll back down, the radio sropped
playing, and my door locks stopped working. The
passenger side window still rolls down though
Take the door panel off again on the drivers side, unplug the window motor and put a test lite between terminals then operate the window switch if the light lights in both directions replace the motor if it lights on one or none replace the master switch, you may have knocked something off when installing the speaker so check closely check to see if the speaker wires are touching causing the radio to stop. I hope this helps. Take care.
