No rear brake light / turn signals on 2001 Chevy Cavalier
My 2001 Cavalier has lost the rear brake lights and turn signals and hazards. The center brake light still works. I have checked the bulbs and all the fuses in the fuse compartment everything checks good. The front turn signals work, the back up lights work which is part of the same bulb so I assume my ground is good. coincindently my odometer display light quit at the same time, all the gauges work and the dash lights all work. Any ideas on where to look next?
Re: No rear brake light / turn signals on 2001 Chevy...
I had the same problem and fixed it by spraying a small shot of wd40 (or contact cleaner) on the hazard switch and moving it back and forth a few times. I was about to buy the switch and heard about this, worked like a champ and was free!

Yes, it does have a flasher, although it may be a combined unit with the hazard flashers relay. So you hear the clicking of the flasher relay? That seems to indicate the relay is working properly. Have you checked the bulbs and the turn signal fuse? Any turn signal bulbs light up anywhere, front or back?
How about your brake lights, do they work? Your car may have separate, stand alone turn signals in the rear, but many American cars use the same bulb and same filament on the bulb for the brake lights and turn signals. If your merc is like this and the brake lights work, then the bulb must be good. Turn on the hazard flashers and see if all bulbs work and flash at each corner of the car. This would be the same bulb as for the turn signals. If they work, it could be a bad turn signal switch, may even be the flasher relay somehow malfunctioning, and in a few cases, a bad hazard switch can affect the turn signal switch. Check fuses and bulbs first. If you have any type of body control module that controls lights and other accessories, you may have to investigate that. I know I'm not being very helpful, just throwing out a few suggestions. Good luck.
I'm checking into that same problem for a early 90's buick ( it's a GM also ) , I've checked the obvious ( bulbs, flasher,fuses,etc) all where fine. I assume your front turn signals work if you manually operate the turn signal switch or put on the hazard switch? The Buick's rear lights won't come on even with the hazard switch on. When you say one tail light has been out for some time, do you mean the brake/signal light or park/running lights? The Buick was like that with one side out for a while ( brake/signal light) but both the rear park/running lights work. Now, I've narrowed the problem down to the turn signal switch. I'd bet money on it. I just have to dig out my steering wheel puller, bite the bullet and get 'er done. You should be carefull if you're attempting that repair yourself ( AIRBAG ), use a manual. ( You could do a quick test by trying the turn signal while you pull the bottom of the arm toward you,move some of the wiring in the column near the arm,etc. I did and the signals started working. Could be the switch,dirt or a broken/loose wire. there's a lot of wiring going through the column and a lot of movement ( turn signal,high beam,cruise, then add tilt) Hope this helped.
I had this problem, and to be honest, it happened to the left side about a week later...it's the board that the bulbs plug into...it's a very common problem with this model. So popular that you can normally get the socket board off the shelf at a parts store! it's extremely simple to replace, and I replaced all the bulbs at the same time!
1. Check for power to the turn signal switch on the White and Yellow wires with the brake pedal depressed. If low voltage, check the stop light switch operation on the brake pedal. Check the Center High Mount stop light (CHMSL) circuit operation.
2. Check the black wires at the turn/brake sockets for a good ground.
3. If all OK, check for a bad frame ground to battery negative.
4. and dont forget to check the rear bulb
I have a 2002 Chev Cavalier that had the same exact problem. I replaced the bulb harness (purchased from a chevy dealership for around $5) which was fairly easy to do. I have had zero problems with it since.
