Should be attached to the passenger side firewall or passenger side on heater box in vehicle. What's the problem with it? If it runs at all you can listen & track it down.

My 1994 acura legend ac only works if i turn it on full blast


High speed only is caused bu a defective blower motor speed control solid state resistor. The resistor is located in the air ducting (for cooling) next to the blower motor under the dash on the passenger side of the car. Remove the lower dash panel to access the part. See picture below of resistor.
Cost for part is about $200.00

How do i get my blower motor on 1994 jeep cherokee to come on?


If you put the control inside the vehicle on and the blower does not come on first check the fuse for the blower circuit, next check to see if you have voltage on the motor terminals...if no volts then you can check the resistor block on the air plenum(these things go bad all the time) the block controls the different speeds for the motor..if you have voltage on the blower motor then the motor is bad...no voltage then may be resistor block or switch inside cab.

2005 jeep AC and heater blower only high speed works


check fuses, then wiggle speed control while moving, may need new dash control for lower speed, usually high speed works through relay may be the reason high speed works

2005 Jeep Grand Cherokee. Htr/AC fan switch only functions @ highest speed. At lower speed settings I can hear doors opening and closing---but not air.


replace the blower motor resistor. It controls the fan speeds. It defaults to high speed only when it fails.

How to replace the blower motor resistor block: Caution: Stay clear of the blower motor and resistor block (Hot). Do not operate the blower motor with the resistor block removed. 1. Disconnect and isolate the battery negative cable.
2. Remove the glove box from the instrument panel.
3. Pull out the lock on the blower motor resistor wire harness connector to unlock the connector latch.
4. Depress the latch on the blower motor resistor wire harness connector and disconnect the connector from the resistor.
5. Remove the two screws that secure the blower motor resistor block to the HVAC housing.
6. Remove the resistor block from the HVAC housing. Installation:
1. Position the blower motor resistor block into the HVAC housing.
2. Install the two screws that secure the resistor block to the HVAC housing. Tighten the screws to 2.2 Nm (20 in. lbs.)
3. Connect the wire harness connector to the resistor block.
4. Push in the lock on the blower motor resistor wire harness connecgtor to lock the connector latch.
5. Install the glove box.
6. Reconnect the battery negative cable.
7. Have a nice day!

I own a 2005 jeep liberty. the ac, heater fan only works on selector switch setting # 4. nay sugesstions on why fan does not work on settings 1, 2 or 3.


The lower speeds are accomplished by running the power supply through various resistors that drop the voltage which makes the blower turn at different speeds. The lowest setting uses all the resistors to drop the voltage as much as possible to turn the blower as slow as possible. High speed uses no resistors so the blower gets full power and turns as fast as possible.

Since speed 1 and speed 2 use the speed 3 resistor to drop there voltage and speed three is not working as well my guess is the speed three resistor is burnt out in the device referred to as the blower motor resistor or blower motor speed control module. This is located near the blower motor and is held in place with 2 screws. There will be several wires and possibly two connectors plugged into it.

These are really common failures in many vehicles. The parts are usually available at your local auto parts store and they are typically not that expensive.

Hope that helped.

Have a 2003 Jeep Wrangler, Rubicon and the hear/AC blower fan only comes on in the high position. The other setting low, med and med/high the blower will not come on. Is this the controller it self?...


The problem usually stems with the blower motor resistor,high speed by-passes it and there-fore the controller is sending power but the resistor has gone open and the speeds can't be regulated.

blower motor resister has burnt out also check wiring going to your blower motor resistor these must have a good tight connection or they will burn if any sighns of being hot change the complete wiring pig tail to your blower resistor
