The taillights and brake lights do not work?

Hi,

Based on what you described, it sounds like you have a faulty ground for the rear lights. All the rear lamps use a common ground.

You indicated the brake lights work with the lights off but not when they are on. I suspect the ground just isn't strong enough to handle the load.

The ground for the lamps is on the driver's side between the rear wheel and the bumper. It will be a black wire. Check the condition of the connector. Also, I would suggest removing the retainer, sanding to the metal, and then reattaching it.

Try this and let me know what you find.

Take care,

Joe

I have a question. You indicated when the lights are on and you press the brake, the light flickers. Which light are you referring to? Also, do lights such as license plate lamps and backup lamps work?

I went through the schematic again. There is a stop lamp relay which when actuated sends power to the turn signal/hazard switch and then to the brake lamps. See pic below

Do me a favor. Remove the relay in the under-hood fuse box and inspect it. If the relay is good, I suspect the problem is tied to the signal/hazard switch.

I attached a pic below showing the wiring. If you want, check for power at the switch with the lights on and then off. See if it changes. If there is no change, then I am back to a ground problem because from that point, power goes to the brake lamps.

Let me know what you find or if you have questions.

Take care,

joe
