2001 grand prix gtp head lights and dash lights dont turn on, the brake lights and fog lights work, but no head lights or dash lights

It might be a bad headlight switch good luck

reach under bumper twist bulb pull out do not unplug. unbolt 2 bolts on headlamp assembly pull straight out

it all points to a fault with a common ground. Find earthing points

relay or control module is faulty.

Have your battery tested or first clean the terminals and cables. Check the ground cables, not just the one on the battery but frm engine to body etc etc.

Here you go.

1995 grand prix truck release and backup lights dont work

first check the head light bulbs if good and fuses good its most likely the headlight switch in the dash also test the dimmer switch it could be bad this is all that could be wrong in a normal situation

Check the head light switch and the ground of the fuses.

how do you replace a headlight switch in a 07 grand prix gtp. head lights do not come on. all other lights work. fuses are good. amd so are the bulbs. was told that the headlights themselves were not getting a charge. and was told that it was the headlight switch.
