I was trying to switch out my factory stereo with an aftermarket stereo. It ended up that I need a wiring adapter before I can do so, therefore, I put the factory stereo back in, I did not modify anything at all.
Now, the airbag light is on and the AC does not work. The AC light and the recirculation light both do not turn on. I have checked the AC fuse in the engine compartment and it is good. Anyone familiar with the electrical system have any ideas of what to try next?
