To replace the blower motor speed resistor in a 1999 Ford F-150, first, disconnect the vehicle's battery to ensure safety. Locate the resistor, usually found near the blower motor under the dashboard on the passenger side. Remove the electrical connector and the screws securing the resistor, then replace it with the new one and reattach the connector. Finally, reconnect the battery and test the blower motor speeds to ensure proper function.

Heater fan switch works only on the highest setting?
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.
How do you replace a blower motor speed resistor on a 2002 vauxhall vectra?
Ask a guy
Blower motor works on speed 4 but not on speed 1 or 2 or speed 3?
Need to replace the blower motor resistor which is located just under the passenger side dash. 2 bolts on either side will remove it. Cost of replacement resistor is about $20.
2001 echo heater fan only has high speed is it the motor or switch?
It is the resistor, replace it.
What would cause my blower motor to only run at high speed on my 1998 Chevy Express?
The blower motor speed resistor is burned out. The resistor is usually found close to the blower motor. Auto parts stores carry that part and it is easy to replace.
Why does the fan on your 1997 Plymouth voyager only work in low and high speed?
The blower motor speed resistor is burned out. Keep in mind that in many cases the speed resistor burns out because the blower motor is failing and drawing to many amps. So if the new resistor burns out soon, next time replace the blower motor also.
Your heater blower will just work on high speed?
The blower motor speed resistor is burned out. The high speed function bypasses the resistor. The speed resistor is generally located near to the blower motor.
The low speed and second speed blowers doesn't work for the blower motor?
the reason blower does not work on all speeds, is the fan blower motor resistor. The resistor is a 4-5 step series circuit, 1 resistor is added for each reduction in speed. If one burns out then so will all speeds below it. The "high" circuit usually has a separate fuse and bypasses the resistor altogether.
Why does the heat blower only work on low and medium but not on high?
It could be due to a faulty resistor in the blower motor circuit. The resistor regulates the speed of the blower motor, and if it malfunctions, the high speed setting may not work properly. It would be best to have a mechanic inspect and replace the resistor if necessary.
What does it mean if the blower fan in a 2001 Dodge Intrepid will only work on high speed?
replace the blower motor resistor
What is a resistor block for on a Dodge Caravan?
The resistor block or blower motor resistor is used to control the speed of the blower motor. That is how you get the lower speeds on your air conditioning or heater. The higher the resistance the lower the speed of the motor.
Fan only blows on high no low or mid speed 2001 maxima?
The Blower Motor Resistor Pack is defective. Replace it.
