The relay is most likely on the passengers side fender under the hood. If its like my 1997 its in a black box with fuses and relays. You push a clip on the side of the box to open it up.
If your fan is running on high only it is probably a problem with the blower resistor. This is located on the passengers side interior just below the glove box. There should be a access cover. After removing it you can see the blower resistor. Most of the time there is a red clip on the connector. Push this back and then you can depress the connector. There should be two screws holding the blower resistor in place. You will see a cover on the resistor. Pry the tabs up on the cover and pull the cover off. You will see two springs (resistors) and what is known as a thermal fuse. The fuse will actually look like a large electronic resistor. Mine on the 97 was blue on one end. Take a short piece of insulated wire and bend it where you can make a jumper to complete the circuit of the theral fuse. Do not connect the jumper wire yet. making sure the ignition switch is off, plug the resistor module back into the connector. Do not install it into the heater shroud. Now turn you ignition on and place you heater on the on position with the fan switch in the 2 nd position. If the fan does not run it is likely the Thermal fuse is blown.
Being careful to only hold the plastic case of the blower resistor, take the jumper wire and touch it to each end of the thermal fuse. If the fan starts running the fuse is bad. You can either buy one from Mopar $60 plus or go to Radio Shack and get just the Thermal fuse Part # 270-1322. Make sure you read the heat caution on the back of the package. I soldered new connectors onto the contacts and then crimp fitted the new Thermal fuse to avoid heating it up too much and blowing it. Make sure you know which end of the fuse was on the lead end. Compare your new fuse with the old one and install it in the same position.

Where is the resistor on 2001 jeep wrangler
under the dash below the glove box
The blower resistor is behind the glove box door.
If it works on some speeds and not others, the most likely problem is a defective Blower Motor Resistor Pack. It is located near the blower motor.
Either your switch is messed up, or more likely the blower motor resistor is bad.
your blower resistor is going bad
Go to Wholesalemopar.com and search for your wrangler, keyword "resistor". Two parts will come up, I believe they are the same, but one has a link to a schematic for blower assembly. Good Luck.
Replace the blower motor resistor.
Pull out the lock on the blower motor resistor wire harness connector to unlock the connector latch . Depress the latch on the blower motor resistor wire harness connector and disconnect the connector from the resistor. Remove the two screws that secure the blower motor resistor block to the HVAC housing. Remove the resistor block from the HVAC housing............
No. The ac and heater fan only has one resistor. The control switch is also failure prone on that vehicle.
maybe blown fuse or the connection in the blower resistor is damaged or the blowre resistor module is burn out the blower resistor is located in front passinger under the dach boared
Could be a bad resistor pack at the blower motor Could be a bad low speed relay
