Why doesn't my AC & heater on my 99 Dodge Stratus not working

SOURCE: 2004 dodge stratus heater/ac issues

I had the same problem with my '97 Stratus. There is a large resistor in the fan motor circuit that has died and needs to be replaced. It's well up under the dash, behind the glove box if I recall correctly, so unless you are a contortionist and have the tools, have a shop replace it.
