How do you turn off daytime running lights on a 2001 Pontiac Grand Am?

I believe on almost any GM/Chevy/Pontiac vehicle you turn off DRL by pushing the dome light round grey switch, underneath the headlight switch. It will cycle between dome light on/off and DRL.

How to turn off the daytime running lights on your 2002 Pontiac Grand Prix GT you bought headlight covers and it looks stupid with the lights on?

open the fuse panel to expose the fuses. If there is a location guide or chart of fuses, remove the one labeled "drl." If there is no chart, look in the owners manual, it is listed with a diagram. I have found this to be the easiest way on a 97 model. On a 97 there is two fuses that control drl, one is a shared fuse and one is only drl. Make sure you pull the one that is strictly drl if yours has it.

If you lift your ebrake handle one notch, it will not engage the brake, but it will turn off your drl's. Or you could always pull the fuse.. :)


What would cause the headlights and instrument panel to short or intermittently come on and off as if there was a short on a 2002 Pontiac Grand Prix?

When i was trying to disable my DRL's (Daytime Running Lights) i pulled the fuse for them and my headlights and instrument lights were flashing intermittently. Check the fuse panel in the glove box and look for the DRL fuse. Check if its blown. Hope this helps!!!
