Question: 1993 mitsubishi diamante ES 3.0L SOHC
my parking and dash lights have gone out and one of my tail light fuses keeps popping everytime I turn my lights on.Could it be a relay causing these problems,if so,which one or ones?
Answer: Asa,
It sounds like either your headlight switch has gone bad, or you have a short in your system somewhere. It's not easy to find a short since you most likely have to take several voltage readings to be sure you have continuity throughout the entire circuit.

Another possibilty that your car's computer is shorting out your headlamp circuit. Read this article for further information:

If your ECU is malfuctioning, it can very well cause these strange problems. Have it checked by a qualified mechanic.
Good luck!
