Passenger tail light out. Replaced the blub still not working.
Turn signal and brake light work on left light assembly. The tail light does not
with a new bulb inserted. Possible socket plate assembly issue.
All brake lights not working
replaced taillight circuit board
rear tail lamps stopped working when the car was only a year or two old. we found out the part(s) were recalled so we took to the dealer and they replaced. the replacment lamps have been working fine for several years. no cost to me except for time off from work spent at the dealership and time off from work to go to court to answer the ticket i got.
both backup lights wont work
We bought out Chevy Trailblazer at 65,000 and rear lock wasn't working,replaced under warranty and then after inspection tail light was out. I replaced the bulb and working again next morning not working so put in spare bulb. Working again. Filled up for gas and not working so back to store for a pair of bulbs. Installed them and it worked. But again not for long. Always just for hours not days. After testing some of the old bulbs I figured something was awry. MacMulkin fixed it and then driver s side doing same thing but this time I was smarter. I sort of knew it was lens / light socket assembly. Now to figure out where to gt one that works. Do I do MacMulkin and do it my self or have them fix it. I sure hate to think they might of switched sides for circuit assemble is the same only actual lens is different. We have to have truck inspected this week so I will try and see if corrosion is doing the nasty. I can make light work by a sharp thump along side of tail light unit. It will last for a few minutes.
Pulled over for no L rear running light at night. Turn signal and brake light worked. Light socket plate was badly corroded and could not be removed from rear light assembly. But replacement of entire L rear light assembly with inexpensive aftermarket replacement was extremely easy and quick using online instructions.
Replace it 3 or 4 time will never but another Chevrolet GM
I have to replace bulbs all the time.
Back-up light socket went bad, only minor problems with this car, We purchased it new and have been well pleased..
Driver side tail light works but brake light doesnt not come on. Top and passenger brake lights do. Changed bulbs and still doesn't work.
Left rear tail light out. New bulb and new circuit board. Reverse and brake lights work
Tail light and break light on right side do not work. We've replaced the whole light fixture and it still does not work.
I had both brakeklight and reverse lights go out,decided to try and swap them from side to side and they started working again,just got this truck and already having problems with squealing under load as well.

I have had continual problems with the right tail light. I had the recall done but it still goes out after replacing the whole assembly
Left rear lamp socket melted. Replaced with aftermarket unit.
