Hello, I was driving today and all of a sudden I cant signal and AC just went dead (no lights either). Hazard lights flash and all lights on dash work along with radio but now the airbag light is on. Any ideas?

Additional information is needed. The assumption is that you've already done the no-brainer tasks like checked ALL the fuses in both the engine bay and cabin fuse panels.

1. What year FJ?
2. Please provide a list of ALL electrical functions that work normally, and those that don't: HVAC blower, wipers, interior lights, horn, door locks, etc.
3. ANY non-OEM electrical system modifications of ANY kind?

Sorry, its a 07. Literally everything works except ac and signals. The lights for the signals work on the dash and outside when using the hazards. Checked under the seats for loose cables but nothing is loose. Getting odb code P0705.

No obvious common factor here ... are you in an area where there's any possibility of rodents chewing on the wiring harness?

Are there any signs of rodent activity in or around the engine bay ... nesting materials, droppings, etc.?

Possibly the easiest things to look at first is chasing the P0705 code. Does the transmission gear indicator in the instrument cluster properly indicating the gear selected as the shift lever is moved through the various positions?

Check the wiring harness at the transmission range selector switch on the RH side of the transmission, and trace it as far forward as you can, looking for any evidence of insulation damage.

You didn't confirm that you had checked (pulled and visually inspected, or pulled and checked continuity with a multimeter) every fuse in BOTH fuse panels.

Or respond to the question about ANY non-OEM electronics ... is there anything other than the "after market stereo"? is this just a replacement head unit, or is there an external amp somewhere, and/or a non-OEM backup camera?

Okay, sorry for the lack of info, been insanely busy. So today went out and found that a 15 amp fuse under the dash, the IGN 1 fuse was blown, sure enough it was the culprit. I have added a 50" LED bar, leds in the wheel wells and most recently a set of LED headlights. Im guessing the headlights are possibly the reason the fuse blew. The rest of the lights have been on for a while with no issues. Thanks guys for all the help.

Jeez, it goes without saying that for ANY electrical system fault that suddenly appears, CHECK THE FUSES FIRST.

2 minutes spent visually checking the fuses would have taken less time than the 3 forum posts asking for help.

From the 1st post response to your request for help:

"The assumption is that you've already done the no-brainer tasks like checked ALL the fuses in both the engine bay and cabin fuse panels."
