When you say, "My air and heat stopped working", it raises many questions to clarify your concern. My best guess is that you mean no air is blowing out the vents. There are a few reasons this could happen. Yes, there is a fuse that if blown would affect the blower motor's power (Maxi-fuse #105 in the fuse box near the battery...it's 40amps...or...fuse #7 in the dash, a 5amp fuse...or fuse #24 in the dash, a 10amp fuse). If those fuses check out OK, then you could have a problem with your Electronic Automatic Temperature Control (EATC) system, or the Blower Speed Controller within that system. Last, you could have a blower motor that simply will not work anymore. Good luck with solving your concern!
