Tail Lights

I have a 89 f250. anyone know why and how to fix this problem. I have no Tail lights..brake,turn, head lights all work but no tail lights.

Or if anyone has a FSM for a 89 f250.....thanks

do you have dash lights?

Check your brake light switch located above the brake pedal.

all lights work but the tail lights

do you have dash lights?


Where exactly... do you have an pic?

The brake light switch is located on the brake pedal arm about 9" above the brake pedal. The plunger from the switch extends when the brake pedal is pushed thus completing the circuit and turning on you brake lights. Their is 2 wires connected to this switch and should be the only switch attached to the brake pedal assembly under the dash.

I have brake lights just not tail lights

Hmm, an '89...

For memory here, there should be a connector under the master cylinder that runs down to the left frame rail, check for power to one pin with the parking lights on, and see if it goes dead with them off. If that's ok, move to the connector next to the fuel pump on the left inner frame rail under the driver's seat. If there move the the connector at the REAR of the rear tank (if equipped), and check for voltage (battery -0.5Vdc), if ok someone probabally installed a trailer light wiring kit and wrecked the wires near the bumper/left frame. You can patch if necessary, but a rear harness from a wreck would be a much better option.

tow package was installed at one time but wires all cut
