New to the forum and to dodge so sorry if these questions have been previously posted...

My air bag light in the dash came on and stayed on for a few days.. It came back on and is now staying on. I don't no what is going on with it but any advice would help.

My a/c and defroster buttons arent working and the yellow blinking light wont stop or go away... any suggestions?

Thanks and again sorry if these topics were previously discussed.
