Airbag, Dome Light & Stereo turn off and on randomly

I have an electrical issue which started following an accident and repair. The front drivers side was knocked in but damage was limited to front bumper, driver side quarter panel, and driver side wheel and assembly.

As soon as I got my vehicle back from repairs the Air Bag, dome light, and stereo/CD player would lose all power, and the Air Bag light would come on. Randomly I can be sitting in vehilce, driving, or come back to the truck after it's been parked and the 3 would either have power or not opposite of what it was when I left it. Sometimes the power stays on for a day or so, then just loses all power. I had a new GPS system installed and it continued to do the same.

Couldn't be a fuse, and doesn't seem like a short since when the vehicle is parked and there's no movement it will just suddenly turn on or off. The 3 components have to be somehow wired together, but no idea where or why it's having the power issues.

Looking for thoughts from this forum and possibly a fix. Thank you!

 

Check the Short Pin (may be labeled ST Pin) in the underhood fuse box, I bet you will find it's not installed properly or is burnt.
