It's the resistor pack. It's a common Dodge/Jeep issue. This is a circuit board that has a couple of resistors (Stepping down the voltage from your battery to run at the lower speeds. High speed gets full voltage)
Dealership should have the replacement for $20 or less. Get the new one before you take the old one out so that you can see what it looks like, what to look for and how it goes in.
Removal is simple. Unplug the wiring harness from the connector. Remove 2 screws and it'll drop right into your hands.
Installation is just as simple. Hold the new one in place and replace the 2 screws. Plug the wiring harness back in and you'll be good to go!

Heater / air conditioner fan control doesn't engage fan. Previously, it only worked in high speed.


I would replace the blower motor resistor first then see if that corrects this. The resistor is located next to the blower motor under the dash.

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

Jeep cherokee 2000 heater fan does't run


If it doesn't run on any speed then check fuses and relay's under the hood in the power distribution box,if all are good then use a test light or volt meter on fan motor wires with fan switch set on high,if you have power there then replace fan motor,if the fan works on some speeds and not others than check the fan speed control module,it is located in the air duct on pass side below glove box.

2001 Jeep Wrangler heater blower stopped working


Yes I would go with the switch, BUT, does it have a resistor bank? That is, how does it reduce the speed? Many systems use resistors to lower the speed. Burnt or bad connections can cause this as well.
You can test the blower motor by connecting direct power from a source like the cigarette lighter if you are handy.
Most of the time the lower speeds konk out but the high speed continues to work this is the resistor bank that goes out.

Heater fan only works on "high speed"


All cars are designed with a blower fan motor that pushes air through the ventilation system. This air is processed by a series of vents to direct the air to various positions. Example: heater, air conditioner and defrost modes. Most blower motors are power by a basic electrical circuit that utilizes a multi resistor or a solid-state resistor to control different fan speed modes (low, medium low, medium and high). If the resistor malfunctions it may lose one or more of the lower fan speed settings.

Heat/AC Blower fan speed only works on High


Alot of people have the same problem with the fan switch and blown bulbs. There really is no fix for this. Jeep really screwed up when designing the heater control assembly. The cheapest solution is to buy another unit off Ebay. Can always go to the dealer but be ready to PAY for there mistakes.

Fan motor switch on 98 jeep cherokee only works on high


In many cases this is the result of the blower motor resistor having gone bad. They are often located in the housing that holds the blower motor but I cannot say 100% for sure with the Jeep Cherokee.
