Today a front turn signal lamp burned out. It doesn't look like there is much access from the engine compartment to reach it, only a small triangular hole. Is this a dealer only repair? Does the whole headlamp assembly have to be removed to reach it? Since it is a lamp, I assume that it is not covered by warranty. Has anyone had to change one of these?

I had both of them burn out in my 2004. Both were replaced by the dealer under warranty. I think they have to remove the entire assembly.

Thanks for the help. I'll call them tomorrow.

Please note!.................They make everything to be replaced by GM, gone are the days of getting into the engine compartment of a 57 chevy with your engine.

When they changed out one on mine they had to remove the front wheel and go in from the wheel well. I was told they found after-the-fact it could be done with the wheel turned all the way in, however it was much easier with it out of the way.

marvowen:

A couple of questions;

1. What year is your XLR?

2. Does the turn signal lense look like it has crystals all over it?? IF SO, you have a factory replaceable problems that requires that the entire headlight bucket be replaced. In my and sevveral others case, they replaced BOTH headlight assemblies which inclued a wiring harness modifcation and new electronics for the lights. The cost for the parts is about $1,000 EACH PLUS the labor.

So head for the dealer and Get'er Done!!!

I just had my lights replaced because of this same thing. They also install the new wiring harness. Not sure what that is going to do, the lights still look as brite as before.

One thing, from the outside the lights look the same on the car but when you are seating inside the car you can see the rubber that goes around them sticking up. Has anyone else seen this difference or did they just not install them right?

I appreciate everyone's input. It sounded pretty easy so I decided to do the job myself. Mine was not the crystalized problem, just a burned out lamp. Anyway, I took the front wheel off and then took the seven snaps and screws out. Once the access panel was off, I still had to take nuts off the three studs on the headlamp assembly. The headlamp then slides forward and lifts out of the body. It was then easy to access the lamp socket. One interesting thing about the bulb itself, it is a 3757 amber bulb and the auto parts guy tried to sell me a 3157. The 3157 is available almost everywhere, but I had to go to a Cadillac dealer for the correct 3757 bulb. It's GM part number 10319395. The dealer had offered to do the job on warranty, but he's 22 miles away so I took care of it myself. It cost me $6. Thanks everyone.

BTW, the holes for the headlamp studs are fairly long slots, so if you can see weatherstrips from the driver's seat, the headlamp assembly was probably not slid in far enough before being tightened down.

FWIW: There are white plastic shims on the studs. They are used for aligning the headlights to conform with the fenders. If you can see the lights while sitting behind the steering wheel then you need to return to the dealer and have them adjusted to your car.

I had my headlamp units replaced recently and now when I wash my car I have water vapor inside the top of the clear plastic cover, anyone else having this issue?

The harness is used because the replacement headlamp assemblies are for '06 and up and the two harnesses are not compatible. The brightness will be the same with the new units.
