Replace fan switch.
It is the resistor, replace it.
It could be the high speed heater motor relay is stuck on or the switch itself is broken.

fan speed control switch is bad. Replace it as long as the other speeds work fine.
replace the switch.
If you have no blower speeds at all, first check the fuse. If the fuse is okay I would suspect the blower speed switch and its electrical plug has melted. If the switch checks okay I would suspect the blower motor is bad. If you have high speed only, I would replace the blower motor speed resistor. If you have all lower blower speeds but no high speed, replace the high speed relay.
Switch problem? Cables disconnected?
Yes there is, but it only operates the high speed function.
How do you replace the safety neutral switch on a 1995 Jeep Cherokee 5-speed transmission and Where is the safety neutral switch located?
bearing is out,replace motor.
The blower motor speed resistor is burned out. You can replace only the resistor but the resistor probably burned out because the blower motor is going bad. If you want to fix it for good, replace both the blower motor and blower motor speed resistor.
