headlight assembly on 1997 Pontiac Firebird

The driver side side headlight assembly works fine but the passenger side does not come up when the lights are turned on. The motor has been checked and is fine and all the fuses are okay. What could the problem be?

Check power and ground at the motor. If the motor's good then there's no power or ground or the motor would operate. If no power or no ground, check for good connections.
Thanks for your prompt answer. my husband has tried about everything but i'll see if he did this.
