Thread: Dash lights - blowing fuse

Now I can't say this definitively applies to your car but typically the dash lights and tail lights on most vehicles are wired into the same circuit the headlights have a circuit and fuse all buy themselves. So it might be worth going throughthe tail lights and making sure they are not full of mud dirt or corrosion causing a slow short. The other thing to think about is when does it blow ie after the first brake application? or after the first time you go around a corner and use the indicators, just a couple of simple ways of narrowing things down.

Well its not the headlight switch and the trailer cable looks ok.

This is a great idea. Will test drive and see when it actually happens.

I think you are right. If I read RAVE correctly the RHS front park lights and tail lights share the same circuit coming from common fuse and trailer cable is picked up off the RHS tail light wire.
