I own a 1987 Chevrolet truck (custom deluxe)step side. When the headlights are on the right rear turn signal will not work. When the headlights are not on it works fine. Whats the problem?

The brake light, and turn signal, use the same wire and bulb filament. Your bulb will have 2 filaments in it. One for the parking lights, one used for turn signal, and stop light. Your question should state, when My parking lights are on, my turn signal does not work.
There is not one answer for this. But I am going to guess a bad ground, a turn signal filament that broke and fused to the parking light filament, ( check the filaments in the bulb) The other explanation would be if someone had just messed with the wiring, The most likely problem is a bad ground.
If the filaments are okay, take a test light, ground to the vehicle, and test the two contacts in the socket, making sure not to touch the side of the socket wall with the test light. (Direct short that will blow fuse) With both parking, and right turn signal on, one contact will be a steady light, (parking light) If the other contact blinks, your problem is a bad ground, because the test light is acting as a ground. If this is the case, just run a wire to the vehicle body( metal) , and connect it to the ground wire of the light socket.

It might be a problem that the body of the truck, surrounding the light might have so much body repair (plastic) that there is no more grounding for the light. When the headlights are off, the signal light gets some grounding back through the tail light bulb and wiring through other bulbs of the circuit to the ground . That route for the circuit to a ground isn't credible when the tail light circuit goes 'hot'. Try putting a grounding wire from a mounting screw of the light pot to a piece of solid metal (well brushed off/cleaned off) and fasten it with a screw or clamp.

Happened to me once. Turned out to be a loose wire in the headlight plug. Took me forever to figure it out but I reconnected the wire and everything was fine.
Go figure.

Replace the bulb. Filament problem as stated above. Tricky problem to diagnose.

Repair or replace the ground wire to the lamps.

you want to interchange the bulbs in the front or one way or the different finished the circuit. try putting a bounce cord the position you bumped off the bulbs.If it blows the fuse then you truly favor to interchange the jumpers with diodes or resistors or some thing.

you may need a new fuse.
