Loose wire?
i have one myself..it does the power windows, power locks, etc
In the fuse box
The fourth fuse in the interior fuse panel controls the power windows and locks on 2000-2001 Grand Prix. 25 amp silver fuse.
It is the same fuse labeled for the door locks, "DR UNLK"
I would check the wire harness and conectors to the doors because the poswer locks, windows, and mirrors are all conected through that harness.
Bad fuse
Remove the power locks and windows fuse you will loose power for your windows also
Key combination [Windows+L] locks Windows XP.
Check the wiring in the door jamb area where it bends and flexes
Key combination [Windows+L] locks Windows XP.
A very common problem is to have broken wires in the harness going to the driver side door.
whats the problem?
