Hi - I have a 2006 Aerio SX - about a year ago the fuse to my radio, gas guage, and dome light kept blowing. After numerous trips to the mechanic and not finding anything, it was determined that they thought it was my cell phone charger. Every time I took the car to the garage I removed my charger to take with me (plugging it back in each time the fuse was replaced), the mechanic would replace the fuse and everything would work. I stopped using that charger. I have used that power source with my GPS with no issues. I had not had any other issues until yesterday. The fuse blew again (with nothing plugged into power source) - I was at a gas pump with my ignition switch set to where just the radio plays and when I got back into my car I heard the 'pop' and the fuse blew. Replaced the fuse when I got home and everything was fine. Made a stop at lunch today - ignition was turned completely off. Started car and 'pop' fuse blew again. I'm stumped. Any ideas?
