electrical issue effecting several circuts at once

My 06 Tacoma has an electrical issue which happened today with no warning, the air bag light came on just after starting to pull off from a stop, pulled over put the trans into park and shut off the engine waited 20 seconds and restarted air bag light stayed on, trans would not come out of park had to use the manual over ride, check engine light came on, turns signals stopped working, AC stopped working, cabin fan blows on high only, windshield wipers stopped working, washer part still works, and gear indicator in dash will not show selected gear. checked the fuses all look to be okay. Truck starts lights work radio works windows work remote keyless entry works. Any thoughts ?

 

Its hard to imagine that all these separate systems would have a common fuse or even a common ground. Have you checked all of the fuses inside the cab as well as under the hood?

 

Check the IG1 and IG2 Fuses with a meter.

 

+1 Check IG1 and IG2 fuses as stated above.
