Test Step
Result / Action to Take
N1 CHECK THE BLOWER MOTOR
Ignition OFF.
Disconnect: Blower Motor C2004.
Connect battery voltage and ground to the blower motor.
Does the blower motor operate?
Yes
GO to
N2
.
No
INSTALL a new blower motor (19805). TEST the system
for normal operation.
N2 CHECK FOR VOLTAGE TO THE BLOWER MOTOR
Ignition ON.
Place the function selector switch in the floor position.
Measure the voltage between the blower motor C2004, circuit 371 (PK/WH) and ground.
Is the voltage greater than 10 volts?
Yes
GO to
N3
.
No
GO to
N4
.
N3 CHECK THE BLOWER MOTOR GROUND
Ignition OFF.
Disconnect: Blower Motor Resistor C293.
Measure the resistance between the blower motor resistor C293 pin 2, circuit 261 (OG/BK) and the blower motor
C2004, circuit 261 (OG/BK).
Is the resistance less than 5 ohms?
Yes
REPAIR circuit 57 (BK). TEST the system for normal
operation.
No
REPAIR circuit 261 (OG/BK). TEST the system for
normal operation.
N4 CHECK CIRCUIT 371 (PK/WH)
Disconnect: Blower Motor Relay C2017.
