Driver side power window on a 1999 chevy silverado LS won't go down. passenger side window works. bought new switch, nothing changed. bought new regulator with motor and still, nothing changed. i haven't tried a new fuse (circuit breaker type relay) because i figured if the passenger side window worked, the fuse is not blown. what next? the wiring? how do i check/fix that?

Sounds like your gears are striped out inside the motor. I had the same problem on a car of mine. I just went to a parts store and bought the gear and took the motor apart and fixed it myself. It cost 18 dollars with tax.

Good Luck.

REMOVE THE DOOR PANEL TO GET TO THE WINDOW MOTOR. REMOVE THE CONNECTOR ON THE MOTOR. LOOP A TEST LIGHT FROM BOTH TERMINALS. WITH THE KEY ON AND BOTH SWITCHES IN PLACE, CHECK TO OPERATION OF THE SWITCHES. IF THE LIGHT COMES ON IN BOTH DIRECTION THE WINDOW MOTOR IS BAD.

THERE IS A CIRCUIT BREAKER BUILT INTO THE WINDOW MOTOR. SOMETIME HITTING THE MOTOR WITH MAKE THE CIRCUIT BREAKER RESET BUT THE MOTOR WONT LAST LONG DOING THAT.

ALSO TRY PULLING DOWN ON THE WINDOW WHILE TRYING THE SWITCHES. THE WINDOW COULD JUST BE STUCK. THIS HAPPENED TO ME.

Testimonial: "Thanks, BB1BUD. I ended up replacing the entire regulator with a part I ordered online. So far so good."
