Check the brake light switch. It should be energized when the switch is depressed. (constant power in and power out only when pedal is pressed) Taillights and signals power through the steering column and light switch. BUT first check the fuses. I seem to remember there being a fuse for the truck brake lights and another for the trailer brake lights. Use a tester and check trailer wiring brake lights. If they work, look for the truck brake light fuse.

Taillights are not working. Brakes lights and turn signals fine, but no taillights. Checked the fuse and it's okay. Any ideas?


Try unplugging the connector from the brake light switch( under the dash on the brake pedal arm) Install a jumper in the plug and see if the brake lights come on. If they do, the switch is bad. The new switch must be adjusted correctly or the brake lights will stay on all the time. This circuit has power even when key switch is off.

check park/tail fuse regarding dash ,park ,tail problem .brake light on passenger side is probably the brake globe needs replacing .Turn signals on passenger side could be globes or switch,check globes first ,if globes and fuse are ok ,may well be the switch especially if park switch and turn signals are on the same switch lever/stalk

The turn signal switch in the steering column has a short in some models. Have someone watch your brake lights and move the 4 way flasher on top of the column from left to right without deploying the switch for the 4 ways. If your brake lights flash ,the harness needs to be replaced if they are still available. Harness around 300.00 plus labor.

Could the dashboard switch (for the lights) or wiring. Possible one of the harness connectors got unplugged. Check the trunk are and under the dashboard.

I think this is a mechanical problem ... when you brake it refuse to send a signal to the tail lights.
I suggest that you need to check the terminal block connection between them.

It sounds as if you have a bad earth to either one or both of your rear light clusters. If it only happens when you indicate in one direction then that is the offending side.

No brake lights when i push the pedal


Its the signal light switch on the lever.
THe signal switch has all connections relating to the brake lights!
solution play around with the lever and see or get someone to see the brake lights work with the brake pedal down.
My car does the same thing! when i move the lever towards activaiting the high beams the brake lights work.
just gently push on the lever to see the lights go on.
you have to replace the switch and requires removing the steering wheel without setting off the airbag.
