79' z28 turn singal problem

My left turn singal works fine but when i turn the right ones on the rear stays soild and the front dosnt turn on at all. Also I don't hear the relay click from inside the car. Visual examined the wires they all looked fine but still not getting power to the frount blub. I did try replacing the blub but still nothing.

Also the harzards don't work. The left turn singal arrow on my dash dosn't light up. I hear the relay click when turning right but not left. When I turn the headlights on the right running light turns on with the head lights and the right turn singal lights up. But the left running light stays off with the turn singal, but the head light turns on

If you are not getting voltage to the lamp housing in the front then you must check your wires and connections again. Old mechanical relays will not cycle unless there is a larger load on them this is why the light will stay solid on the side with the inop front signal.


If the connections and wires are good and you have replaced the lamp then I would be looking at the lamp fixture itself.

Best of luck

i'v checked all the wires and connections, they all seemed fine. I think the lamp fixture is fine becuase it gets power when you turn the head lights on (the turn signal turns on for the running lights not the turn signal)

The parking lights won't affect the turn signal prong. You know you are getting 12v and ground to the parking light side of the lamp but don't know if the turn signal part is working.

Did you probe the turn signal wire already?

I hate to tell you but you may have to follow that wire back to see where the break is.
