:confused Has anyone else out there had a rear tail light malfunction. I remember watching these new impalas, monte carlos, and other chevy's before I got my SSR last year and noticed that quite a few had rear tail lights out on one side or the other. I was hoping this was not an indication of what was to come, but here we are. I have a tail light malfunction (at least it's not a wardrobe malfunction). They ordered a new tail light assembly and it should be here soon. Just curious if anyone else had this problem. The bulb is fine, the assembly is "Kaput".

Re: Taillights

I have an '02 Trailblazer and have replaced the rear stop and turn signal bulbs at least twice each in about 32,000 miles and less than 2 years.

The problem as I see it is the thin wires that are on the bulb which make contact with the socket. They are not the older style 1157 bulbs that you pushed in and turned, where the round large base of the bulb was the contact.

The wires either can't handle the current or the contact is not tight enough, but you get heavy arcing on those wires which eventually acts as an insulator. The bulb is not blown, just that the contact area is bad.

I applied some dielectric grease last time I changed the bulbs and so far so good, but I don't know if that's a long term fix. Also the socket contacts are so flimsy that they won't hold any adjustment to tighten them.

I have heard rumor that GM has a technical service bulletin issued regarding this but have not seen it.

Hope this might help.

Enjoy the ride.

Mike

Turned out to be a loose connection where the wires meet in the middle between the two tail lights.:):cool
