Asked by MLongmire Oct 30, 2011 at 08:44 AM about the 2007 Pontiac Grand Prix Base

Question type: Maintenance & Repair

We have a 2007 Pontiac Grand Prix.  We have replaced the bulbs and checked the fuse which was okay but the front headlights still will not come on.  The bright head lights and running lights still work.  We had it put on the machine and the person said it was a wiring issue.  How do we replace the  wiring for the headlights?

i had a similar issue, check the housing unit to make sure its not corroded causing the lights to not turn on. if not that follow the wring the best you can and see if there are any cuts or nicks in the wires causing no power sent to the lights keeping them from turning on

I had the same exact issue with my 2000 grand prix. In that insance it was a faulty parking brake switch. The parking brake deactivates the headlights and DRL.. Depending on which headlight switch you have, GMs column mounted headlight switches are notorious for going out and only killing only the low beam headlight function (marker lights and high beams still work). The dash mounted switches do not have the same issue. Hope one of them help you.

the ebrake will only cut the drl's not the headlights if u turn them on manually, does the fan for the blower work my ign switch failed and the fan only had high speed and when i had it on any lower speed the drl's shut off and the headlights also did if they weren't turned on manually.

Faulty neutral safty switch... try moving the gear shifter back and forth from park to 1st over and over again. the lights should eventually start working again. its happend to our 07 GP. A few times and its always worked.

Just had the same problem with my 2006 pontiac grand prix. The headlight switch was replaced with no luck. The fuses and the headlights were checked and they were both fine. Finally it was figured out that the relay needed to be replaced. Hope this helps all of you fellow grand prix owners!

I just bought a 2006 gxp and d/s low beam was working and p/s low beam wasn't. I decided to replace both low beams and when I did this, both light don't work at this time. there is no power going to the low beams at the harness, and at the fuse box...what can this be?

PROBLEM SOLVED...I have a 07 grand prix 6 cyl. and the low beam headlights would intermittently shut off a couple times a month. I replaced the headlamp relay ACDELCO Part # 15016745 it is $25.79 at rockauto.com. Its been 2 months without any problems.
