Hi everyone,

My son's 2004 Sunfire has an electrical burning smell while driving.
The car behaves normally however the odor smells like burning insulation or electrical components overheating. The smell seems focused near a large aluminum heat sink mounted near the passenger side firewall under the hood. I can see two (2) larger electrical wiring harnesses plugged into this same assembly. If anyone can help troubleshoot please reply.

Thanks so much,
Mark62

Pictures would help but wouldn't the best thing to do before something catches fire be to take it to a shop?

That is the plan.
The car is parked till it travels to a shop.
What I see online is this vehicle had an unusually high number of odd/weird electrical problems.
Nothing yet exactly like we're seeing but still odd things that seldom have happened with all of the cars we've owned through the years.

I had a 2003 and kept it till 2008 and never ran into an electrical issue. Only thing not related to normal maintenance was replacement of a camshaft actuator solenoid, about a 15 minute job. Good luck with the car.
