A/C fan motor only works on high. Need how to info to replace switch for fan motor control


Your problem more than likely isnt the switch for the fan control, but the actual Blower Motor Resistor is bad... here is a helpful diagram and "how to" on replacing the resistor.

Hope this helps...

1999 jeep wangler blower good new switch new resistor still dont work


Did you replace the bloer motor also, usually a resistor failure is caused by a failing blower motor. here is a diagram to help with diagnosis, Make sure you have voltage at the blower motor connector with the key on. If not verify the fuses and the blower motor relay shown in the diagram. If voltage is present diagnose the ground side. The ground path goes from the motor, through the resistor, through the selector switch, then to the ground listed in the diagram.tj910157.gifnosis.

Durango vent blower fan


The blower motor resistors are known for going bad. Usually its because the blower starts drawing too much current. What I would recommend doing if you can and have the tools, is to check the blower motor connector to make sure 12 volts is present. If so than I would recommend replacing the blower motor resistor. Then if the same issue ever happens again and the blower motor resistor is bad again, you will need to replace the blower motor and the blower resistor as the final repair.
Here is some info about testing the resistor using a multimeter it you have one:

DIAGNOSIS AND TESTING- BLOWER MOTOR RESISTOR WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
Both the front blower motor resistor and the optional rear heater-A/C unit blower motor resistor can be diagnosed using the procedure that follows. For circuit descriptions and diagrams, refer to Air Conditioning/Heater in Group 8W - Wiring Diagrams.
  1. Disconnect and isolate the negative battery cable.
  2. Disconnect the wire harness connector from the blower motor resistor block.
  3. Check for continuity between each of the blower motor switch input terminals of the resistor and the resistor output terminal. In each case there should be continuity. If OK, repair the wire harness circuits between the blower motor switch and the blower motor resistor block or blower motor as required. If not OK, replace the faulty blower motor resistor block.
Here is the information on replacing the resistor:

REMOVAL
  1. Disconnect and isolate the battery negative cable.
  2. From the passenger foot well area, remove the two hex screws used to secure the blower motor resistor.
  3. Unplug the front blower motor resistor from the wire harness connector.
  4. Remove the front blower motor resistor from the HVAC unit.
Here is an exploded view of the HVAC box. The resistor is #63 in the picture and the actual part may appear slightly different:

If any issues such as no voltage at blower connector or damaged or melted connector at the resistor then let me know.
