2001 Pontiac Grand Prix power windows an door locks inop all fuses and relays ok?

If the power Windows and door locks on your 2001 Pontiac Grand Prix are inoperative despite checking all fuses and relays, the issue may lie in the wiring or switches. Inspect the wiring harnesses for any damage or corrosion, particularly in the door areas. Additionally, test the window and lock switches for continuity, as a faulty switch can prevent operation. If these components are functioning correctly, the problem could be in the body control module, which may require further diagnosis.
