tail lamp fuse - I know another thread but this is not my first go

[Moore]

I'm posting as a last resort as I've been working on this goddamn electrical problem all week.

Taillamp/interior light fuse blows. I can get it work until I start the car. So ignition off lights on fuse stays on, then start car and blow.

I've taken out all bulbs and tested front rear and sides, 1 by 1 to see if that makes a difference. Removed my centre console checked radio illum, and gauge illum wiring nothing to be found. Removed wheels and looked for any rubbed wires going to front lights and side markers nothing found. Rewired front lights without the plugs as they looked a little corroded - no change. I've gone as far as cutting my front bulb holders out in case they were corroded, made no change.

Removed headlight switch and checked for corrosion but it seems to be okay. I'm still leaning towards the headlight switch because of the fact they blow when I turn the car on but I don't want to throw money just guessing.

Is there anything else I'm overlooking?

Check the wiring in the trunk. If you have carried anything heavy that could move around you might have pinched some wires that run right behind the tails inside the trunk. I had an issue like that.

Damn spent all that time tearing apart the car looking for a broken wire to ended up figuring it out as just being the ground wire's that attach to the rad support behind the headlights.
