what doesnt work and it all stopped at the same time-------power windows,alarm,gauge lights, shifter lights,
blinkers,hazards,tails.
this has happened before and it all came back on 2 days later but not this time. i think its a short somewhere i just wanna know if any ones knows anything more than that.

 

Sounds like a fuse, check your fuses and let me know what you find.

 

Pa always said, keep your car simple. However, all that electronics at times can become a nightmare. Sounds like a short and if so that alone can really be a big pain in the POOP!!! If ya can't figure it out, some shops charge a flat fee to locate the short and additional cost to repair. Good luck!!! Lets us know how ya made out!!
