2004 Chevy Trailblazer
Engine size = 6 cyl.
Warning lights = no
GM Computer codes = no
Repairs for this problem = Replaced headlamp socket
Question = The low beam headlamp on the drivers side melted the socket about two months ago.I
replaced the socket with a generic from Napa. When this happened it did not blow the fuse. The
lamp did not blow,also there is no moisture in the headlamp area.I have now had the same
problem again. I noticed on your website and some others that this seems to be a fairly common
problem. When I replaced the socket I used crimp style butt splices with watertight shrink tubing.I
noticed that there are hi temp sockets available would this help.I do not think the replacement that
I installed the first time was this type
Answer: You need a good quality socket from GM. It comes
with the required heat shrink connectors. Also, if you're
running an aftermarket bulb, or have some other than stock
headlight system, that causes an overload on the circuit and
will melt sockets. For example, the blue lights you see on
foreign cars. Make sure the new socket is wired correctly and
always use new bulbs after doing a repair. Even if the bulb is
not blown, it can be faulty and causing a heavy draw. Visit
your local dealership for the correct parts.

Chevrolet Trailblazer 2002 l/s. Engine size = 4.2
Question = The inside under the hood caught on fire. Not the engine or transmission, the windshield
cooler, where you put the antifreeze and maybe where you put freon for the  air
conditioner, i like to know if it is  worth repairing, no damage to interior of the car just under the hood.
Answer: It's all up to you whether it's worth fixing. I can't be a
judge of that. If you're willing to spend the money to fix it back
up, and want to keep the vehicle, then go for it. If there is a lot of
damage, or you don't want to spend the money on it, then don't.
If it's in nice shape otherwise, it may be worth keeping and fixing,
but again it's all a judgement call on how much you want to do.

I have repaired many of these at my dealership. There is an updated plug from GM to address
this issue. You can also order ceramic plugs on the Internet that can withstand the draw and
heat from the bulbs. You might also want to upgrade the wires to the headlamp socket to a
thicker gauge, the wires from the factory are tiny.
