faulty blower motor resistor. The low and medium speed on blower motor is
controlled by resistor and its actual speed is high. So because resistor is not
working, blower motors actual speed which is high is working.
can be faulty blower motor or faulty blower motor resistor. Get the blower
motor inspected. If it's faulty it has to be replaced.
blower motor testing and replacing, check the link below: ----
Remove the glove compartment liner to gain access to the heater blower motor and blower motor wheel assembly mounting screws.
Use a small screwdriver to remove clip retaining hydraulic damper strut.
Remove four screws and remove the heater blower motor assembly and blower motor wheel assembly from the heater blower motor housing.
Using a new seal, position the heater blower motor and blower motor wheel assembly to the heater blower motor housing with the flat side of the flange near the heater blower motor switch resistor (18591). Install the four retaining screws.
Tape the heater blower motor power lead to the air inlet duct to keep the wire away from the blower outlet during installation.
Install the heater blower motor and blower motor wheel assembly in the vehicle.
replace the blower motor speed control resistor, the thermal limiter is most likely blown in the resistor, the resistor is located next to the blower motor, see picture below, the aprt is very cheap to buy and takes only minutes to replace
If you can, check if there is voltage at the blower motor connector with the ignition on and the engine not running. If you have voltage, the blower is bad. If no voltage, it may be a bad blower switch, the blower motor resistor assembly, or the wiring between them.
The resistor assembly is on the evaporator housing under the dash on the passenger side and near the blower motor. The glove box must be removed to check this and the blower. A thermal limiter resistor is built into the resistor assembly and will open, ie melt, with excessive heat.
Without more details on this, it appears either your blower motor or the blower motor resistor assembly is bad.
