My heater and A/C was working fine one day and then the next day I went to turn it on and it didn't work. It doesnt do nothing, it doesnt blow air or anything. Where do Istart to find the problem and how do I fix it?
Check yoru fuses first, then if you have a test light, test to see if resistor an drelay are getting power, they are by the blower. One or both cold be bad or the control unit may be bad. You also might try takeing the fuse out and putting back in after a minute or so. Otherwise you'll need to have it scanned to see what 's wrong.
