Re: GXP Fog Lamp Replacement
I'm on my third set with only 9,000 miles on the car. I called the Pontiac service center to see if they have anything from any dealers about similar problems with the lights. Thier reply was that they haven't heard of any problems

I have a friend with a Chevy pickup. His second in a row, in fact. He had the same problems, and the dealer replaced the bulbs several times. We finally figured it was moisture. We removed the assemblies, cleaned and dried everything very well, and put a very thin skim-coat of clear rtv on every mating surface that may allow moisture in. No problems since.

fog lights
One thing that may help prevent 04 and 05 fog lights from burning out(in case noone else has thought of this) Keep your fog light switch off unitill you use them.;then turn them off again when done. By keeping the switch on all the time,during the day while your Daytime running lights are on so are your fog lights! I just happened to notice this last week on my 05 GXP. I would think these high intensity bulbs being on all the time(day and night) would burn out fairly quickly. I know turning the fogs on and off after each use is a real pain but it just might solve the problems that so many of us have.
I hope this helps. Please send your checks to................. ha ha just kidding!

Thanks. Your info helped me alot. Yet another example of useful and time saving information from this forum!
GXP Fog lights -
Might I add for those who are as dumb as I that to get that motherf***ing clip back in while pinching off circulation to your upper arm and pulling out your shoulder while leaning on your tire, that you need to start by threading the open end of the clip in on the "RIGHT" and then swing it back toward the light bulb until you find the place to "click" it in. This needs to be done while holding both the bulb and the clip with the one hand that you can get back in there (if your are going through the inner fender as I did).
The guys at Mr. Goodwitch replaced the entire forward wiring harness and the bulb blew only 3 hrs later. I think the boys must have jarred the bulb too much. It didn't look new, either.
This operation was so simple to do in my SSE. Why'd they go and make it so hard in the GXP???

The fog lights on any Bonneville, GXP or not will remain on if the button is turned on, but one of the big problems we have been having with the fog lamps is a bad ground in the light itself, rerun the ground and most of the time you will not have anymore problems. Also if you just take the headlamp out you can get to everything you need to through the gaping hole where the headlamp used to be

I have 40,000 KM on My 05 GXP, and I have replaced each bulb at least 4 times. I had it in last tuesday, and the following morning, one was out again!!
At the dealership, they simply reach in from the top, and it doesn't seem to take long. I think they just pull the headlight bulb out of the way, and presto, they can change the fog lamp bulb.
I am just gonna keep taking it in until they get sick of dealing with it and force a fix.

LEN/05gxp, the TSB'* for current GM models is mind boogling, so You have to take the initiative to inform Dealers of them at tmes so they get it right. This is one of those times. 
Give them the text and TSB number I have listed below and tell them a new lower fog lamp wiring harness has been made to put them on the right track.
