Car has about 121,000 miles and runs fine. Awhile ago, when I turned on the a/c, the fan wouldn't come on immediately. I moved the switch to its highest setting and it would then kick-on. This didn't happen all the time, just on occasion, but it would always kick on by doing this. Anyway, now that it is a bit cooler here in the Orlando area (40s-50s in the mornings), the same thing happened when I had the heater on. Until Yesterday, now nothing happens. No fan at all. Checked all the fuses and they are fine. Is there some simple solution or sequence I can follow to see what causes this? Many thanks.
