Blower location
A - blower fan
B - fan motor connector
The blower fan is located under the glove box.
Blower Motor Resistor Test
Resistor contacts | Resistance |
2 and 4 | 0.83 ohm |
2 and 3 | 1.12 ohm |
1 and 3 | 1.74 ohm |
Checking the blower speed switch
Examination
1. If the blower fan is not working, first of all, check the connections of the connectors in the fan circuit. Check fuse 2 on the fuse panel located under the dash. Check the blower relay in the fuse and relay panel under the hood.
2. Determine the location of the fan relay. Remove the relay and check if it functions correctly. If the relay is defective, replace it.
3. Set the gearshift lever to the park position and put the car on the handbrake. Turn the ignition key to the ON position without starting the engine.
4. Check how the fan works in all modes.
5. If the fuses and relays are OK and the fan is not working, test the fan itself.
Connect the tester to the blue and red pins. The tester must show at least 10 V - the ignition is on, the fan mode switch is in any position except the OFF position (Turned off). If not, there is a problem with the fan circuit.
6. If power is supplied to the fan and it does not work, connect the black/white wire to ground on the car body with a jumper. If the fan still does not work, then it needs to be replaced. If the fan is running, it means there is a problem with the fan's ground circuit.
7. If the fan works, but not in all modes, check the fan resistor, which is located on the fan shroud (indicated by an arrow).
8. Remove the resistor and inspect it for damage. Check the resistor with an ohmmeter. Replace resistor if necessary.
9. If the resistor functions normally and the fan still does not operate in all modes, remove the heater/air conditioner control panel. Disconnect the wires from the back of the fan speed switch and check the resistance of the switch. If the switch is defective, replace it.
