I have a 2008 Dodge Charger and yesterday the heater/ac would not come on and the airbag light came on. Could this be a problem with a fuse and if so which fuses do I need to check? I am a single mother of a senior in high school and with money being an issue right now I need to try and fix this issue myself if at all possible. PLEASE HELP, any suggestions would be greatly appreciated. Thank you.
