Turn signals don't work '80 280ZX

[bcharmane]

So what I've seen so far is that this is a regular occurrence. When I bought the car the turn signals worked but as soon as it started raining they went out. The lights don't flash on the dashboard nor the outside. But when I turn my hazards on, they show on the dash and outside. What could this be?

clean bulbs end and sockets starting with the front.

Also replace rubber parts of your light units... its leaking.

Does that explain why the lights don't work on the dash?

[Martzedcars]

When moisture shortcircuit the bulbs the cligno shuts down and none of the lights wil flash including the ones on your dash! So, Yes!

BTW Hazards lights are controlled (I think) by a heavy-er cligno.. because now it has to work with twice as much lampbulbs

Get a multimeter and start measuring ! Turn on the turn signals and measure if you have a 12v pulse going to the turn signals. Put Multimeter on 12 DC

So: Put left turn signal on, and start measuring on the connectors of the front and rear left light bulb. You should measure at least a max peak of 9 volts.

If not, go measure voltage @ the flasher relay. This way you can trace the problem.
