Just got this back on the road after months of sitting, parked it with no problems. Started it up and drove to work, turn signals working the whole way. I work swing shift so I go home at night. Start the car, turn the lights on and leave the parking structure, go to turn ..... Signals aren't working ... >.>
Hazards work fine without headlights on and with them on.
Headlights off = Signals Work BUT Headlights ON = Signals won't work.
Fuse, Wiring, I have no idea? So I came here >.>

When you say Headlights ON = Signals won't work..

Do they light and not blink.. or not light at all.

They do not light at all.

See if this applies to you...

I was futzing around with the hazard lights to turn on the signals, they both work with the headlights on. I pulled up on the hazard button after the lights were off and somehow with the lights on the signals work now. I guess the hazard lights are causing an interruption?

Wow. Now I've gotta check mine. I needed some dielectric grease anyway.
