Electrical Problem

[oneton77]

Greetings,

 

I own a 2003 Blazer 4wd with a horrible electrical issue. I have torn apart the dash and have looked high and low and cannot find a bad wire or loose ground anywhere. I will just list the symptoms of my electrical issue and maybe someone out there can know where to look or what is wrong with the truck. It still runs and I drive it to work eveyday, but here is the list of issues:

 

Airbags deployed for no reason while driving (previous owner).

Can't put cigerrette lighter fuse or cruise control fuse in; both blow instantly

Most gauges and dash lights inop unless right rear window is rolled down and switch is held in down position.

Power locks inop; windows can only be rolled up/down from drivers door.

Rear hatch/window inop as well as wiper and defrost

A/C doesn't work/heater/fan will only blow out of vents

Daytime lights not functional

 

I'm sure I'm missing a few things as well but those are the main issues. I hope someone out there can help me solve this mystery. Thanks for your time.

No on the flood damage. It was my fathers truck after the airbags went off he was gonna junk it. I took it instead to drive back and forth to work in the winter. According to him everything was working in the truck, then one day he noticed a small puff of smoke from the fuse panel. After that he had a few of the issues then one day the airbags went off. He just went out and got a new truck and never messed with it again.

This is why I'm parting out a rust free southern '00 GMC Jimmy. I chased electrical gremlins in mine for so long that I just gave up.

Sounds like multiple issues to me. Possible liftgate module for the rear issues...

I've only seen one non impact deployment and it was caused by a water leak and sdm wet/corroded.

Hvac mode or defrost actuator stuck

and the list goes on...
