Q: Turn signal fuse keeps blowing.

asked by on

Turning on the turn signal blows the fuse after about 3 to 5 seconds of use, even with a 25 amp fuse installed in a 20 amp circuit. The hazard lights work fine.

First of all, you should never install a fuse with a higher amperage rating than what is specified. Fuses are designed to blow at a certain amperage rating to protect the rest of the circuit. If the fuse keeps blowing, there is a short somewhere. A factory wiring diagram will need to be consulted in order to hunt down the short. A technician well versed in electrical repair will be able to diagnose and repair your problem. I suggest the professionals at YourMechanic.

Q: What do the turn signal indicators mean?

The turn signal indicators are located on your instrument panel. When one of these lights flashes, then the corresponding turn signal is currently turned on. When both of these lights flash simultaneously, then your hazard warning lights are on.
