So, i got my car back with a new diff and its been running great until just about 20 min. ago. Mechanically it seems to be alright, no power loss or anything like that, but my computer, my guess, has lost its mind. Auto-lights don't work, tach speedo and gas gauge all at 0, radio off, steering wheel controls do nothing, windows wont move. Also sounds like theres a giant AC under my hood and there's a lot of air coming up from in front of the engine block, the air is cool so i think it's just being blown by the fan but it shouldn't be running at full blast when my car is sitting still.

The good news is my CEL is off (probably because the computer no longer sense anything let alone an engine problem).

Has this ever happened to anyone? I couldn't find it anywhere.

 

some of those things sound like front and rear sam. someone with more knowledge of what is controlled by the sams will be able to tell you which or both. i do know that the gas gauge is rear.

 

Sam? if that has anything to do with the fuses its not that i looked through every fuse and there are none that are missing or broken. The fan blowing, i think, is because the computer cant tell what temperature the engine is running at so it just blasts it to keep it cool. it seems to me that the only thing that is wrong is the computers ability to gather information from any of the sensors because everything else seems to be running just fine.
