My 94 Dodge Spirit, yesterday all of the sudden lost the use of the turn signals. I have checked the fuses and they are all good, and I also changed the flasher, but still have no turn signals. What could be my problem?

Check/replace the turn signal multi-purpose switch. Try spraying the switch with electrical contact cleaner or WD-40 before replacing.

. Try checking all under-dash and under-hood fuses with a test light or multimeter. Here's how:

Doing it this way, you also test for voltage through the circuit.

. Check for voltage at the Turn Signal Switch. This may involve checking the Hazard Warning Switch, since voltage to the Turn Signal Switch may come through the Hazard Warning Switch.

. Check for bad grounds. Using a test light, probe the turning signal light sockets for voltage. Sockets may need cleaning. Apply dielectric compound to base of bulbs.
