Last week when the dealership was diagnosing my vehicle, "something" happened ... they said something about a blown fuse, but I haven't spotted anything blown. However, I've lost my turn signals. Headlights and running lights still come on, but no turn signals. No relay ticking, no signal lights lighting (I don't think). The 10A fuses under the hood for left/right signals all look OK.

There seems to be a ticking or humming noise coming from near the firewall on the passenger side ...

 

is their power to both sides of the fuses? Check it with your test light.

 

Agreed with Ryanmatt135.

Also, if you have a VOM, or anything that can check continuity, check the fuse itself. Have seen fuses that look good still be bad.

 

If it happened while they were in possession of the vehicle and actively diagnosing it, it's on them to fix it. I'd take it back and tell them you'd like them to fix whatever they screwed up.

 

Do your hazards work? Flasher relay?

 

Unfortunately since that day last week I took it to another garage to get plugs/wires/cap/rotor, secondary AIR pump, EVAP vent solenoid done, I'd guess they would reject my claim.

 

Will check today on hazards. Like I said in the first post though, I don't hear the relay ticking ... but it might not be getting power, right?

 

All two (four, I think?) turn signal fuses look good though.

 

Test light?

 

ha soooo ... hazards don't work. turn signals do. the dealership apparently flipped the hazard switch and left it in the on position ... pushing it back down, turn signals work fine.

so, where do I look to troubleshoot the hazards?
