Tail lights There is no light when driving but have turn single and brake lights. I have lights in the front but no dims for the turn single.

Brake light switch under dash and actuated by the brake pedal lever is out of adjustment or faulty. Adjust or replace it and you'll have your brake lights back. The dim tail lights may just be that you have possible replaced them with the wrong bulbs or the ground to light housing is faulty.

it sounds like you lost ground circuit I believe its a single black wire from circuit board connector to frame One on each side of truck

The front park lights work correct? If the front park lights work than there is not a problem with the light switch since the brown wire from the switch supplies power to the front park lights, front side markers, and the rear taillights. There should be twelve volts on the brown wire from the headlight switch with the connector plugged in and the park lights turned on. If this is true that there is a problem with the wiring to the back of the vehicle. A thorough inspection of the harness should reveal the problem. The dim break and blinkers support the above. High resistance also know as corrosion, in the wires or connections would cause this problem.

head light control module under dash driver side

there must be a short circuit which powers tail lights and brake lights. probably you have a dual filament bulbs which have both brake and tail light together. check for bulb, socket/or bulb housing and harness of that light.

TEST FRONT RIGHT BLINKER CIRCUIT AND REPLACE THE BULB,,WITH PROPER BULB...A DOUBLE CIRCUIT BULB IN A SINGLE SOCKET WILL DO THAT ALSO A SINGLE SOCKET BULB IN A DOUBLE SOCKET HOLDER....CHECK LEFT SIDE BULB FOR ACURANCY

Those trucks have a problem with the circuit board that the bulbs plug into. Unplug all the bulbs and see if one is burnt or melted. The fix is usually replacing the board.

Not posotive with your exact make and model, but their should be a switch directly above where the brake pedal rests normally. It will be a small switch. When you hit the brakes, the switch pops out, and then when it retracts, the pedal itself pushes the button down thus turning the lights off. It shouldn't be but $10 to $15 at the parts store, and installation shouldn't be more than a few screws, and the a small wiring harness clip.

Sounds like you have a bad ground problem or shorted wire.Check for bad grounds rusted or broken.
