Pontiac Problems? Ask a Mechanic for Answers ASAP
You are going to have to pull the door panel off and check to see what is causing the door to not open, could be as simple as a cable that is off the bracket. You may also have broken parts that need replacement.
You have a lock solenoid in the door that controls the power lock operation, this could also be your problem.
Is there anything else I can help you with?
