03 4x4 lbz electronic quirks
 

Hey guys, recently bought an 03 crew cab lbz auto truck and it has some electronic quirks I'm hoping g y'all can help me diagnose. First of all, the readout on the dash doesn't always act right. The odometer won't reset very often when I hit the reset button, when it does I can reset it when getting fuel and when I get in to take off the odometer has moved from 0 to 29.2 miles on the trip. Very strange. Also, the fuel gauge stopped working last wedk, shows empty all the time. Sometimes the low fuel light will also be on, sometimes not. Also, when I unlock the doors with the remote, the mirrors will go to different directions every time. I hit unlock and they will aim at 7 o'clock. Hit it again and they go to 9 o clock. Hit again and they go to 11 o'clock. They will move counter clockwise every time. Hitting the button for the driver 1 I have set won't make them go where I had them set. Have to re aim mirrors every time I hit unlock with the remote. Factory remote fob.

I'm guessing some type of computer has gone bad.

Thoughts?

Nobody has any ideas?

is that alarm aftermarket? sounds like someone screwed up some shit in the body wiring harness

No. Factory key fob

hmm. it sounds like wiring has to be traced, could be shorted wiring somewhere because the mirrors and the door locks end up going to separate modules from the BCM. no codes? at all?

No codes
