Question about 2007 Pontiac Grand Prix

1 Answer

Low beams on my 2007 pontiac grand prix shut off suddenly

Whenever my low beams are on auto eventually as Im driving they suddenly shut off on their own and when I try flickering the light switch on and off it does not turn them on even when I try the manual setting. Then usually they may come on again on their own and may turn back off with no warnings on my information screen. I noticed also if I turn it to the manual setting instead of leaving them in auto they remain on and don't turn off, at least they haven't yet.

Good Evening, I have an odd question because I have seen this once before........ Have you checked the low beams themselves, like take out the bulb and look at the filament? The other thing would be to check for power to the plug in when you unplug the bulb get a test light and hook one end to (-) and the light one to the wire if it doesn't light try the other wire. If it lights do the reverse and hook one end to (+) and then the light end to the other wire you didn't test and see if it lights up. If it lights up on both wires your bulb is bad. I have seen headlamp switches go bad and headlamp assemblies as well. However by far I would check for power out at the bulb plug in and check the bulbs. Hope this helps and if you have any more questions please feel free to ask.

Here is the exploded view of the steering column


Just be very careful when removing the airbag - disconnect the battery and short the circuit before touching the connectors.
Your second problem is caused by a failure of the relay - replace it

Low beam does not work 2006 pontiac gran prix

Joe, It is very likely your LOW BEAM RELAY, they are ONLY $40 Auto Zone or other parts stores. I would have wasted almost a $1000 on parts and labor if my car was not under warranty for all the labor and parts GM certified mechanics wasted replacing a computer brain and the switch on left side of steering wheel. The switch they tried to make me pay for on my second attempt to fix it but but I freaked out on them. My low beams would just go out at any time, very dangerous. This is part # info you need when you go to parts store. You need GM part # 15016745 a.k.a R6100 Mine just says R6100 on the parts box. Look at your manual for its location in fuse box under the hood. It is so simple to replace, a 4 year old could do it. There is reference made on the net by some that Parts stores may tell you the part is a blower relay but ignore that, its for the low beam. Visit this post first to make sure this makes sense to you ok. if the link does not work search "07 grand prix low beam headlights shut off intermittently?" and you will find the forum with at least 20 people who have had this issue. All 06-08 grand prix's should be recalled
I hope I have helped you out.

Pontiac grand prix high beams work but not low beams

I have a 2008 Pontiac Grandprix GXP I had hit a deer in May the repairs were made in June of this year. Here is my problem the air bag light comes on while I'm driving the car and now I have no low beam lights. I have taken the car back to where the repairs were done, cause I think the problems are from the damages. I was informed today that there's no juice from the fuse box to the low beam switch. What would cause this?

2007 pontiac grand prix headlights are not working correctly. High beams work but not low beam. nothing works on automatic. Low beam bulbs have been replaced. Lights worked for one day, then back to not...

I drive a 07 Grand Prix and the low beams randomly went out. Could not get them to come back on, but all of the other lights worked (inside, parking, and high beams). found a forum online that recommended replacing the fuse/thing at location #35 in the fuse box under the hood. It worked immediately!! Got the part at Advanced Auto parts for $35 dollars.

I have a 2007 grandprix..i will b driving and the low beams will just shut off the high beams will work and interior lights all work and the display will say headlamps suggested. they will come back on...

more than likely the switch is dirty or most likely needs replaced....but sometimes the wiring has a bad spot or short..
it's always a mystery with Pontiacs..
check a repair manual for instructions..
switches can be obtained in many junkyards cheaply..
it might be cheaper to start with the turn signal/ light switch.

I have a 2007 grand prix. The lowbeams work but

check the switch it self in the steering column mabe faulty and will need replacing. the high beam switch tend to go bad over time, some has better luck than others, it fairly easy to replace. the switch unit itself operate like a two way switch, one for flashing and other high beam.
