Right turn signal = reverse lights?

Hey guys. 1986 trans am firebird 305, manual. Like the title says, turn signal doesn't work when activated, the reverse lights come on instead. What do I do?

Did you recently buy the car?

It sounds like someone did some “rewiring” to cause that problem to happen.

You will have to physically trace the backup lights circuit to find where the wire(s) have been tapped into.

You can start at the left rear of the car where you will find the connector for the taillight assembly.

Unplug the connector and probe the forward connector.

Connect the probes between the
light green wire and ground.

Now, activate the right turn signal.

Is there power on the probed wire when you do that?

If no, the problem is in the wiring in the taillight assembly.

If yes, the problem is in the remainder of the car.


Happy Racing !
