It took 2 weeks to get my harness.They tod me the bulbs were the same.They repalced both bulbs also.Make sure they replace the bulbs because they can still work but be damaged.One of my bulbs was a lot dimmer than the other one and was going bad.Only a matter of time before it would burn out and looked bad also.

I know this is kinda old, but with the new bulbs, are they a lower wattage than the stock ones? And are they less bright then the stock ones?

Thanks

Same brightness as old bulbs and they said they were the same bulbs as the old ones since they had the same part no.

I am taking my '05 GXP in for this TSB tomorrow. I'm sure they'll treat me like an idiot and be put out that I am actually giving them the TSB # for this problem. I imagine they'll have to order the harness and everything, so it will be weeks before it is fixed. I just hope they don't damage my car like the last time they worked on it!

New harness same bulbs.

Hopefully the dealership will do the work. I have been told that I will have to wait until a bulbs burns out again. By the looks of it others have been lucky enough to get it fixed no questions asked.

No the dealer gave a hard time too first. Then all of a sudden the claimed to find the tsb and would order the harnesses.

I just returned from the dealership. I told the service writer about the problem and handed him the TSB. He said they would look at it. About 1/2 hour later he came back and said that they would indeed have to order the new wiring harness, and that they would need the car most of the day to install it. He said that they would need to remove the whole front fascia to get to the harness for replacement, and would need the car for almost a whole day. I said "No problem, as long as you give me a rental!", and he said "Fine."

On a side note, the dealership also had a brand new '05 GXP in balck inside on the show room floor. The sticker was $38k, but they had it marked down to $31,864. That price is just slightly less that what I paid for my '05 Greystome GXP last July during the employee discount sale. No wonder the car is still setting there unsold. I hope someone gives it a good home soon.

Yeah they gave me an 06 impala while my car was worked on that day. They wanted so badly for me to take a V8 Buick lucerne for 1 night but I declined.

Finally, after 2 weeks, my fog light wiring harness came in. I took my '05 GXP in yesterday to have it installed. They gave me a loaner, because they said it would take 2 or 3 hours to do. They set me up with an '06 GMC Enovy with 945 miles.

About 1:30 p.m. they called and told me the car was ready. I picked it up around 4 and drove it home. When I pulled the car into the garage, I checked the fog light operation. Previously, the fog lights operated with the DRLs. Now, I must have the headlights on for the fog lights to work, and they don't turn on with the DRLs any more. So, something must have changed with the new harness that changes the way the fog lights operate. I will wait and see if the fog lights burn out again, but with them staying off while the DRLs are operating, their life should be greatly extended.

I looked over the work order, and it showed parts and labor for the wiring harness and two fog light bulbs. So, it looks like the dealer did everything they were supposed to.
