Probe 2.5L (Condenser Fan)

Condenser Fan Inoperative

Check 15-amp AIR COND fuse in interior fuse panel. Check 40-amp AIR COND fuse in main fuse panel. Replace blown fuses. If fuse repeatedly blows, go to next step. If fuses are okay, go to step 3).

Checking For Shorted Power Circuit

Turn ignition off. Remove 40-amp AIR COND fuse. Disconnect 10-pin interior fuse panel connector. Disconnect low and high speed condenser fan relays. Using a DVOM, check for short to ground in Blue/Black wire. Check for short to ground in Green/Orange wire at 40-amp AIR COND fuse terminal. Repair suspect wire as necessary. If wire is okay, restore electrical connections and go to next step.

Checking Power Supply

Turn ignition off. Disconnect low and high speed condenser fan relays. Turn ignition on. Measure voltage of Blue/Black wires at both low speed and high speed condenser fan relays connectors. Measure voltage of Green/Orange wire high speed condenser fan relay connector. If voltage readings are 10 volts or less, service suspect wire. If any voltage reading is greater than 10 volts, go to next step.

Checking High Speed Condenser Fan Relay

Turn ignition off. Disconnect high speed condenser fan relay. Apply 12 volts to Green/Orange and Blue/Black wire terminals on relay. Measure voltage of Red/Yellow wire terminal on relay. Voltage should be 10 volts or more. Ground Blue/Green wire terminal on relay. Measure voltage of Pink wire terminal on relay. Voltage reading should be 10 volts or more. If relay fails any of these tests, replace relay. If relay is okay, go to next step.

Checking Condenser Fan Circuit Wiring

Disconnect condenser fan connector. Disconnect high speed condenser fan relay. Measure resistance of Pink wire between high speed condenser fan relay and cooling fan motor. Resistance reading should be less than 5 ohms. If reading is greater than 5 ohms, service Pink wire. Check Pink wire for short to ground. Resistance reading should be more than 10,000 ohms. Service Pink wire if shorted to ground.
Reconnect high speed condenser fan relay. Disconnect low speed condenser fan relay. Measure voltage of Red/Yellow wire at low speed condenser fan relay connector. If voltage is less than 10 volts, service Red/Yellow wire. If voltage is greater than 10 volts, go to next step.

Checking Low Speed Condenser Fan Relay

Turn ignition off. Disconnect low speed condenser fan relay. Apply 12 volts to Blue/Black wire terminal and Red/Yellow wire terminal on low speed fan relay. Apply ground to Blue/Orange wire terminal. Measure voltage at Blue/Yellow wire terminal on relay. If less than 10 volts is measured at Blue/Yellow wire terminal, replace relay. If 10 volts or more is measured at Blue/Yellow wire terminal, go to next step.
Disconnect condenser fan motor connector. Check continuity of Blue/Orange wire between low speed condenser fan relay and cooling fan motor connector. Service Blue/Yellow wire if resistance is 5 ohms or greater. If resistance is less than 5 ohms, go to next step.

Checking Condenser Fan Ground Circuit

Disconnect condenser fan motor connector. Measure resistance of Black wire between condenser fan motor connector and low speed condenser fan relay. If resistance reading is 5 ohms or more, service Black wire. If resistance reading is less than 5 ohms, replace condenser fan motor.
