Did you check the fuses under the rear seat? That's where they blow. There is also a recall on the brake lights to check out.

SOURCE: 2001 dodge neon tail lights inop

looking at your schematics and , you say tail lights don't work , you didn't mention if front parking lights and license plate lights are working , they all come from the same source , a black /yellow wire , a good clue if front work and rear don't , please advise .if fronts work then you have a open circuit somewhere between junction S118 (near breakout for left headlamp) and rear sockets.

SOURCE: brake lights do not work chevy blazer 2001

You have a bad multifunction switch in the steering colum. The same thing happened to me on my 2001 LS Blazer. There was a recall for this item, and if you go to your Chev dealer they can run your VIN and see if it had already been replaced under the recall. If not, you may be in luck for a free fix.

That was not my luck, even though I had the same failure it had already been "fixed" during the recall, and that repair cost me over $300.00

Good luck!

the reverse lights are controlled by and part of the transmission range selector switch, this switch is the large electrical switch on the top of the trans where the shift cable connects.

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!

My brake lights and rear blinkers are not working. I have replaced the bulbs in both brake lights. What next?


most blinkers uses relays, and when they flashes fast one light is out, but you replaced your burnt bulb might be a bad relay.

2002 Chevy Trailblazer Brake lights failure. All Three Breaklights will not illuminate when pedal is depressed. They will work when hazards are on, blinkers, etc. Main fuse under hood is good, bulbs work,...


Well, lets try this, if you have a trailer connector tapped into the tail lights check that for a grounded wire. If a wire has grounded or come free from the splices they won't work.

The brake lights on my 2006 trailblazer are not working, all others lights blinkers etc are working, checked and replaced bulbs and fusses


Thanks for choosing FixYa Rick and welcome. You probably have a bad brake switch. It is located right above the brake pedal in the cab. The pedal hits the switch and activates the brake lights. It is a round looking chrome cylinder usually. Change it and the brakes should work. It cost 10$-30$.

My bottom brake lights dont work 2004 chevy trailbalzer


The recall on those was the boards the bulbs mount too. Remove the lenses and then the boards. See if your bulbs are good and check for fire at the light blue, or brown and white wire. Modle dependant. Good Luck
