Diagnosis Procedure

Use the circuit diagram as a guide to perform the following procedures:
a. Turn ignition switch to LOCK.
b. Disconnect the negative battery cable.
c. Disconnect the HVAC control panel assembly connector K-012.
d. Disconnect the blower connector K-008 and blower speed resistor connector K-004. 
e. Check if wire harnesses are worn, pierced, pinched or partially broken.
f. Look for broken, bent, protruded or corroded terminals.
g. Check if related connector pins are in good condition.

a. Remove the blower.
b. Install the new blower to vehicle.
c. Use X-431 3G diagnostic tester to check if DTCs are still output.
