I have a 2004 Chevy Malibu. and recently, the interrior lights and Instrument/tail lights fuses keep blowing out. I replace them, and the next day or sometimes within hours they fuses will be blown again. My guess is there is a short somewhere, but I have no idea where to even begin to look. Anyone have any advice, or have run into a similar problem?

You are correct,now to find out what circuit is blowing the fuse.If the car was in a accident check that area first.Chances are its interrior or running lights.lets start with interrior lights,install new fuse turn on interrior lights on for 1/2 hour.if fuse blows remove interrior lamp lenses and look for one of the hot wires to be shorted out on the body.To check the tail lights turn off the interrior lights and turn on the running lights.If fuse blows start with any damaged areas,check the trunk area for damage to the wire harness,if you have a trailer hitch chcek the trailer harness for damage.theres no easy fix here,hope I have been some help.Thanks for using FixYa......Ray
