Blower Motor Resistor Inspection
Reference: BLOWER MOTOR RESISTOR REMOVAL AND INSTALLATION
Measure each terminal-to-terminal resistance. If measured resistance is out of specification, replace blower motor resistor.
Blower motor resistor resistance
"H"-"MH": Approx. 0.43 Ω at 20 - 25 °C (68 - 77 °F)
"MH"-"ML": Approx. 0.6 Ω at 20 - 25 °C (68 - 77 °F)
"ML"-"L": Approx. 2.0 Ω at 20 - 25 °C (68 - 77 °F)
