Partial electrical shutdown

[Tiki]

07 Tahoe went crazy today. While I have my truck torn apart, the car alarm for the tahoe went off. I went inside, grabbed the key fob but it didn't work. Walk outside and start it up and the alarm goes off. Shut the car off and the key FoB still isn't working. Then I start the car up and notice that I have a few service lights on

• Service 4wd
• Service tpms
• Hood open

So I disconnect the battery and let it sit for an hour. Reconnect and all the same problems. Go to drive it and notice some other systems not working

• Power windows
• Power locks
• Blinkers
• Rear view camera
• Ear air

Also during this time the radio will not shut off. The radio had all my presets loaded so my guess is that the computer did not reset.


Any ideas before I take it to the theaven dealers on Tuesday?

Best suggestion so far is BCM.

Might be the fuse on the power distribution block on the firewall. Mine was grounding out instead of "popping" like it should have, and gave me all kinds of different electrical problems.

BCM was replaced, all is well, minus my check book.
