I'm frustrated!!
I recently had a mechanic hunt down and oil leak on my 2000 c5.
He. Changed the rear main seal.
Fixed the oil leak BUT NOW when my headlights go up it
blows a fuse and i lose my tail/brake lights , my headlights and motor that puts them down and my trunk release. Change the fuse it good.
I've checked the grounds I could get too without disassembling. Then i tested the hazard switch . Since it was flapping around it was bad I changed it. Still same
I know it's gotta be going to ground somewhere I just got a wire tracker last resort.
Hoping I can get some input before I gotta go through all that.
thanks

When a fuse blows you have a direct short to ground…”checking your grounds” isn’t a way to find your short…what fuse is blown ??…my advise is find an auto electric shop in your area if you don’t have a solid knowledge of automotive electrical systems…unfortunately we can’t diagnose this for you.
