relay harness connector terminal B2 (Dark Blue wire). If test light
illuminates, go to next step. If test light does not illuminate, go to
step 6).
5) Repair short to battery voltage in Dark Blue wire between
blower motor relay harness connector terminal B2 and blower motor
resistor harness connector terminal "C". After repair, go to step 9).
6) Using test light connected to ground, probe blower motor
relay harness connector terminal C1 (Purple wire). If test light
illuminates, go to next step. If test light does not illuminate, go to
step 8).
7) Repair short to battery voltage in Purple wire between
blower motor relay harness connector terminal C1 and blower motor
harness connector terminal "B". After repair, go to step 9).
8) Replace blower motor relay. After repair, go to next step.
9) Operate blower system to verify repair. If blower motor
operates normally, repair is complete. If blower motor is still
inoperative, return to step 2).

1) Perform DIAGNOSTIC SYSTEM TEST. Go to next step.
2) Turn ignition switch to ON position. Set mode switch in
OFF position. If blower motor is off, problem is intermittent. Check
for faulty wiring or poor connections. Repair or replace as necessary.
After repair, go to step 14). If no problem is found, go to next step.
3) Turn ignition switch to OFF position. Disconnect blower
motor relay. Turn ignition switch to ON position. If blower motor does
not operate, go to next step. If blower motor operates, go to 11).
4) Ensure mode switch is in OFF position. Set blower speed
switch at lowest speed position. Using test light connected to ground,
probe blower motor relay harness connector terminal B2. If test light
illuminates, go to next step. If test light does not illuminate, go to
step 6).
5) Check Orange wire between blower motor switch harness
connector C1 terminal "B" and blower motor relay harness connector
terminal B2 for short to voltage. Repair Orange wire as necessary.
After repair, go to step 14). If wire is okay, go to step 10).
6) Using test light connected to ground, probe blower motor
relay harness connector terminal B2 (Dark Blue wire). If test light
illuminates, go to next step. If test light does not illuminate, go to
step 9).
7) Check Dark Blue wire between blower motor relay harness
connector terminal B2 and blower motor resistor harness connector
terminal "C" for short to voltage. Repair Dark Blue wire as necessary.
After repair, go to step 14). If wire is okay, go to next step.
8) Check Yellow, Tan and Light Blue wires for short to
voltage between blower motor switch harness connector C1 at A/C-heater
control panel and blower motor resistor harness connector. Repair
suspect wire as necessary. After repair, go to step 14). If wires are
okay, go to step 10).
9) Check for poor connections or connector damage at blower
motor relay harness connectors. Repair or replace as necessary. After
repair, go to step 14). If connections are okay, go to step 12).
10) Check for poor connections or connector damage at A/C-
heater control panel harness connectors. Repair or replace as
necessary. After repair, go to step 14). If connections are okay, go
to step 13).
11) Repair short to voltage in Purple wire between blower
motor harness connector terminal "B" and blower motor relay harness
connector terminal C1. After repair, go to step 14).
12) Replace blower motor relay. After repair, go to step 14).
13) Replace A/C-heater control panel. See
A/C-HEATER CONTROL PANEL under REMOVAL & INSTALLATION. After repair,
go to next step.
