When to replace the resistor on a Jeep Liberty?
Replacing the blower motor resistor on your Jeep Liberty may be necessary if the HVAC blower motor has stopped working in all but one speed. The resistor limits the amount of electrical current that is fed to the motor, causing the motor to run faster or slower respectively.

How does the heater work on a Jeep Wrangler?
When your Jeep reaches its optimal temperature, its thermostat opens and allows that coolant from the cooling system to flow through the engine, removing heat and sending it into the radiator, then into the heater core which, ultimately, distributes it into the Jeep.
What are the symptoms of a bad heater motor resistor?
Symptoms of a Bad or Failing Heater Blower Motor Resistor. 1 1. Blower motor stuck on one speed. A common symptom of a faulty blower motor resistor is a blower motor that is stuck on one setting. The blower 2 2. Blower motor does not work on certain settings. 3 3. No air from the vehicle’s vents.
Where is the blower motor resistor located in a jeep?
Open the passenger’s side door of the Jeep then the glove compartment door. Access to the resistor is through the back of the glove compartment. Locate the connector latch on the wiring harness connector for the blower motor resistor. Depress the latch, pull the connector off the resistor and set it aside.
Are there any electrical problems with the Jeep Liberty?
210-horsepower 3.7L V6 4-speed automatic 4WD, part-time w/low range TPMS sensor failed, dash warning light on. Replaced sensor. Blower control resistor failed. Replaced. Rear wiper doesn’t always immediately stop when lever is turned to “off” position. Dealership could not replicate problem, or fix it.
Why does my blower resistor keep going bad?
Trent, one of the biggest reasons for blower motor resistors to have shorten life is actually because of faulty blower motor drawing too many amps, some times melting wires/plugs, heating up resistors shortening their life. Many Dodge forums tell of this problem.
How do you remove a resistor from a blower motor?
Locate the connector latch on the wiring harness connector for the blower motor resistor. Depress the latch, pull the connector off the resistor and set it aside. Remove the two retaining bolts from the resistor with a socket, ratchet and extension bar then pull the resistor off the HVAC housing and discard it.
How do you fix a negative battery in a jeep?
Close the glove compartment. Connect the negative battery cable to the negative battery post and tighten the clamp bolt with the wrench until it is secure. Close the hood of your Jeep and test the repair by running the blower motor through each speed setting with the blower switch inside the vehicle.
How do you replace a blower resistor on a Jeep Liberty?
Remove the two retaining bolts from the resistor with a socket, ratchet and extension bar then pull the resistor off the HVAC housing and discard it. Position the new resistor on the housing and install the two retaining bolts, tightening them until they are snug.

What happens when a resistor fails on a jeep?
The resistor limits the amount of electrical current that is fed to the motor, causing the motor to run faster or slower respectively. If the resistor fails, the motor will work at full speed or off but nothing in between. A new resistor is available from any Jeep parts department.
Close the glove compartment. Connect the negative battery cable to the negative battery post and tighten the clamp bolt with the wrench until it is secure. Close the hood of your Jeep and test the repair by running the blower motor through each speed setting with the blower switch inside the vehicle.
