Action
Verify the customer’s complaint.
Are the customer’s concerns verified?
Does the blower run at any speed?
1. Disconnect the power connector from the blower
motor under the dashboard on the passenger side
of the vehicle.
2. Turn the ignition ON.
3. Turn the blower ON.
4. Test the voltage on the connector. The terminal
connected to the BLK/WHT wire is positive and
the terminal connected to the BLU/YEL wire is
negative.
Is the voltage within the specified range?
Replace the blower motor.
Is the repair complete?
Check fuse EF2 in the engine fuse block and F19 in
the I/P fuse block.
Is the fuse blown?
1. Turn the ignition ON.
2. Use a short detector to locate the following
possible short:
From the fuse EF2 to terminal 30 of blower
motor relay.
From the fuse F19 to terminal 86 of blower
motor relay.
From the terminal 87 of blower motor relay to
blower motor.
3. Repair any short.
4. Replace any blown fuse.
Is the repair complete?
1. Turn the ignition ON.
2. Remove the blower motor relay.
3. Using test light check the continuity between
following terminals and ground:
Terminal 30 of blower motor relay.
Terminal 86 of blower motor relay.
Does the test light come on?
Repair the open circuit.
Is the repair complete?
1. Turn the ignition OFF.
2. Set the blower motor switch at 4.
3. Using ohmmeter, measure the resistance between
terminal 85 of blower motor relay and ground.
Is the resistance within specified value?
Repair open circuit.
Is the repair complete?Yes
