So I drove the truck to the store and when I came back out the power windows, sunroof, turn signals, radio, quit working, and the airbag light came on on the dash. Checked the fuses In the fuse box under the hood none noticeably burnt. Any suggestions? Also a little more background the AC has been down for a while when the blower is on and the ac button depressed it starts smelling like electrical fire, however I don't turn it on and it wasn't on when the issue happened. Any help is appreciated, thank you!

 

How old is

 

sorry fat fingers. How old is the battery? Do a charging system check. Check for loose connection.

 

Yeah I'd check all battery and main ground connections, pull the batteries and check them disconnected with a load tester, not just voltage.

In 05 they started using a TIPM, which can cause all kinds of weird crap. I've had good luck with Caravans by simply disconnecting the battery and reconnecting it to reset the TIPM.
