Without Air Conditioning

1. If the Blower does not turn OFF, install a new Blower Switch.
2. If the Blower does not run in LO or MED, check the Blower Resistors for an open resistor.
3. If the Blower does not run in any position, check the voltage at the ORN wires at the Blower Resistors.

NOTE: This check is performed at the Blower Resistor Connector, with the Ignition Switch in RUN and the Blower Switch in HI.



Terminal/Wire color Voltage
B/ORN Battery


^ If Battery voltage is present at the ORN wires and the Blower does not run, check the continuity of the BLK wire at the Blower Motor to ground. If the ground is good, install a new Blower Motor.
^ If there is no Battery voltage at the ORN wires, check the circuit back through the Blower Switch.
