Battery has been good for months now! A few days ago the 2005 H2 (150000 miles) had a weird chime with no dash lights or alerts. Yesterday she started normally but when I shut her off the red battery light dash icon stayed on with the key off and out.

Also when I opened the door the radio stayed on and played delayed power didn't go out. It has never done that before? I had to shut the radio with the on/off vol. button (nav radio) it went off normally but I could hear a hiss noise like radio static? Key was out of ignition.

Later on I drove her and all was good but same happened at shut down. Battery symbol light on and radio played with key out and door open and hiss noise.

This morning the H2 was dead and needed a jump start. Any suggestions welcome?? Please help?

notes since last battery issue I disconnected the onstar with fuse removal and pulled out the nav disc.

New Data: If I pull the SEO ACCY fuse with the Engine off key out (which has a wire from the back up cam wrapped around it) and re-seat the fuse the battery light icon on dash goes out, the PRNDL goes out and the radio goes off. Start the car and turn it off and all hell breaks loose again?

Thought it could be the ignition switch? So I wiggled the key and no joy. Interesting, if I touch the rear wiper sw or the windshield wiper sw with the door closed the battery icon goes out and the retained assy power plays the radio and dash cluster lights until door opens. That's normal. If I have the door open and touch either wiper sw, all power goes off with key out. What does all this mean?

 

this sounds like the problem I just fixed on my 2004 h2. I located several broken wires in my center council attached to the shifter. after taking out my keys the car was still running the accessories. the dealer gave me the pins for free.

 

When the battery light stays on it's just like leaving the key on. I had that problem on my '03 and it was a bad ignition switch.
