Your problem is more likely the blower motor resistor.

Heating and cooling fan not working


sounds like a bad blower resistor.The switch runs a straight 12 volts to the motor in high,but runs through the resistor on the lower speeds.The resistor is located somewhere on the HVAC unit(it requires airflow to avoid premature burnout).

My A/C doesn't work on 1, 2, or 3. It only works when the selector switch is set to high. Any ideas?


There's 2 relays that control the blower motor, one runs low and medium speeds and the other runs the high speed. Replace the relay for the low and med speeds.

2005 Jeep Liberty Heater fan motor speed control , no low speed only med & high speeds..is there a fuse for low speed?


Sounds like low speed coil in the Blower Fan resistor block has failed. The Blower Fan Resistor Block is usually located in the air ducting adjacent to the Blower Fan. The Resistor Block consists of 3 or 4 coils of special resistance wire attached to terminals which connect to the wiring that comes from the fan switch and then to the Blower Fan. The block is on the output side of the fan unit so that the airflow from the fan past the coils inside the duct assists in preventing them from overheating and burning out.
Access to the Resistor Block is from under the dash. To replace, remove the multi-pin connector and then undo the screws holding in the block. Check air duct for leaves and dirt which may have caused the coils to fail. .Replacement is the reverse procedure

I have a 2006 jeep liberty with a 3.7. in normal driving conditions is does not overheat. if i am 4x4ing or with the air conditioning on it will overheat. The electric fans works and the fluid level is...


Do you know for sure if the radiator fan comes on? It should be coming on for the a/c, and it should come on BEFORE the engine temp gauge begins to climb.

Also, do you have obstructions in front of the grill? I would think that you said no blockage to the air intake, but also I could think if you have a winch. Is there any chance you have mud/debris in the radiator fins?

Bugs would be in the a/c condenser. Have you looked at the engine radiator behind the condenser? It's kind of hard to see. You may have to remove the plastic cover.

Make sure the fan goes from low to high speed; when the jeep starts to get warmer the fan should go from the normal low speed up to high (you usually will know it because it really is humming out there on high). It may just be hot enough that low speed can't handle the heat load of the air-cond and the engine in traffic.

The air cond gets the air before the radiator so if the fan is coming on low it will keep the condenser cool enough to have decent A/C performance... the dealer should also be able to test low / hi radiator fan operation.

Tell us news, hope helps.

The blower fan switch only blows on high. no low or med.


Resistor or switch bad. Takes a technician to replace the resistors,. Or replace the climate control console assembly.

2002 Jeep Liberty 3.7L cooling problem (60,000 miles) : it would overheat if driving at low speeds (30mph and under) . Repair shop did pressure tests, results were good. Fan was checked out and was told it...


There is only so much to the cooling system. Although I
should be careful what I say cause my 02 liberty might over hear me and remind me just how temperamental their cooling system is.

I would replace the thermostat and if that didn't work you may want to remove the top plate holding the radiator down to check for any debris that may have collected on the radiator vanes.
I just replaced mine 3 days ago and the part cost around $20 so it's a pretty cheap item.

As long as your not losing coolant then that's about all you can do. If you are losing coolant regardless what the pressure test shows let me know and I'll help diagnose that problem.
Hope this helps.

Aircon wont switch on when motor is running. Fan not working either.


If your fan is not working, the AC is prevented from coming on. This is a safety so the evaporator (cooling heat exchanger) does not ice over.

Fix the fan problem, and the AC will work.

If the fan does not work at any speeds (lo, med, Hi). Then you have a blown fuse or wire disconnect.

If the fan works on HI only, then your blower resistor is shot. This is a common failure and can be replaced at your dealer or by yourself if you are handy.
