I have a 2001 Dodge Dakota. Owned for two years now and well maintained, but my blower control has problems. The heat and A/C work fine, but when I turn the fan on to feel the air, it only blows air out on high. the check engine light is off, and everything is set correctly, but it will NOT blow air on any setting but high. help?

The blower motor employs a new resistor technology to control blower speed. Called the "credit card" resistor, the device looks much like its name in that it is thin and compact like a credit card. The credit card resistor, like the coil resistor used in previous years, mounts inside the HVAC housing assembly in the airflow path. However, unlike the coil resistor, the credit card resistor offers much less airflow restriction.

To replace the resistor, in the passenger foot well area, remove the two hex screws used to secure the blower motor resistor.
Unplug the front blower motor resistor from the wire harness connector.
Pull the front blower motor resistor and its wire harness out of the plenum panel and through the cowl plenum access hole far enough to access the wire harness connector.
Remove the front blower motor resistor from the cowl plenum.
