my air bag light stays on on 2004 Chrysler PT Cruiser

my air bag light stays on, a/c, power windows & headlights does not work on my 04 chrysler pt cruiser, problem started yesterday

You have multiple fuses for your headlamp circuit. #1 in the Fuse Block is for the headlamp relay, Fuse #19-20 are for the Low Beam Headlamps, Fuse #16-17 are for the high beams, Fuse #8 is for the Headlamp portion of the Multifunction Switch. There is no relation that I can see to your A/C, Power Windows and Air bag other than the Fuse Block itself. Make sure you have power to the Fuse Block.
