Blower motor resistor for the Jeep Liberty KJ, including CRD.  The blower motor resistor controls the fan speed.  If your resistor has failed the interior fan will only work on the highest setting.

This is the upgraded version from the Chrysler Sebring/Dodge Stratus.  This version has a strong ceramic heat sheath to keep the resistor from failing due to overheating.

If you are repeatedly blowing resistor switches you blower motor fan might be drawing too much current and should be replaced.  Replacement blower motor fans available.
