Blower Motor Resistor Block

WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, and 2002 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.

For circuit descriptions and diagrams, see appropriate WIRING DIAGRAMS .

Disconnect and isolate the battery negative cable.
Unplug the wire harness connector from the blower motor resistor.
Check for continuity between each of the blower motor switch input terminals of the resistor and the resistor output terminal No. In each case there should be continuity. If okay, repair the wire harness circuits between the blower motor switch and the blower motor resistor or blower motor as required. If not okay, replace the faulty blower motor resistor.
