The door locks on my 96 grand am 3.1 have stopped working, they lock when it is put into drive and unlock only when the car is shut off, the door lock switchs dont work at all. I have checked the fuses and are fine except there is no power going to the one door lock fuse. I dont know if this has anything else to do with it but my air bag light, seat belt light, and coolent light stay on also my front power windows slowly roll down about 5 inches then will not roll up but a tiny bit at a time and i have to let them "rest" then try again to only move the littlest bit. Again I dont know if these are related to the door lock issue or just more problems. I have tried everything I know to fix the locks so if anyone knows anything to try please let me know.

What to check next

Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.

Verify the reported fuse supply with the matching wiring diagram and test the affected circuits under load. Have the airbag and coolant warnings assessed separately rather than assuming one shared cause.

check the main power center under the hood. Sound like the window motors are weak

where is the main power center located? Is that where all the fuses are located under the hood and if so what is it I am looking for?

Discussion summary

96 Grand am door locks

A 1996 Grand Am had inoperative door-lock switches although automatic locking still worked. The owner reported no power at one lock fuse, slow window movement and several illuminated warning lamps.

Reported outcome: No measured circuit fault or repair was reported.

Weak window motors and a main power-center problem were suggestions. The discussion did not establish that the locks, windows and warning lamps shared a fault.
