Blower Resistor

Remove resistor from vehicle, or disconnect wiring in vehicle. With ohmmeter, check continuity. Continuity should exist between terminals No. 2 and No. 4 (approximately 0.4 ohms), No. 1 and No. 4 (approximately 1.3 ohms) and No. 1 and No. 3 (approximately 3.0 ohms. If resistance does not exist as specified, replace resistor. See Figure.
