It's much more likely that the resistor for the switch is bad. I don't know where it is on that truck, try getting a service manual for ~ $15 before you spend too much time trying to find it.

SOURCE: 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.

SOURCE: 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.

SOURCE: 2001 Dodge Caravan heater fan not working on low or medium speeds

Hi ,The resistor is in the heater box located under the dash on the passenger side.It can be seen when you crawl under the dash and look up. It has two or three bolts on it. It will also have a plug connected to it, which has to be disconected.

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.

AC and Heater fan will only work on high speed, all fuses good. any ideas thanks, Dave


When the blower fan will only work on high speed setting this means the fans speed control resistor is burned out, when it fails the fan defaults to high speed only. The fan resistor is located next to the fan and held into the cooling air duct by 2 screws near the blower motor. The part is fairly cheap and easy to replace.

Heater fan motoer only works on high setting?


many of the heater blowers use a resistor type switch to adjust the fan speeds, when the switch goes bad only the high speed will work. the resistor is usually located in the airflow in the heater box under the dash. find it , change it (it just plugs in) and it will work again

HEATER FAN CONTROL DOWN TO 2 SPEEDS


The control is not the problem. Your blower motor resistor is burnt out on two fan speeds.
This is a high failure rate item that the factory has redesigned at least twice for this concern.
