What is the passenger compartment blower motor resistor?
Find out useful information about Blower motor resistor Passenger compartment fan regulator is an element of the car heating and air-conditioning system with the help of which the driver can control intensity of air supply through the radiator into the passenger compartment.
Where is the blower motor resistor located on a Ford Escape?
In the 2008-2011 Ford Escape, the resistor is located behind the glove box on top of the HVAC unit air duct. It’s held by two screws and is easy to replace. See the photo. In the 2008-2011 Ford F150 the blower motor resistor is also located behind the glove box, but is installed in the right side of the plastic air duct.
How much does it cost to replace a blower motor resistor?
The blower motor resistor or control module replacement is not very expensive. For example, one of our colleagues had a problem with his 2011 Ford Escape: the fan only worked at the speed 4. He paid $50 to diagnose and $112 to replace the resistor at a local Ford dealership.
Where does the power transistor go in a blower motor?
The power transistor has 4 wires: two come from the climate control system control unit, one is the ground, one goes to the negative terminal of the blower motor. The service manual advises measuring the voltage at the blower motor, then if not OK, at the power transistor and so on.
Where is the AC blower motor resistor located?
The AC Blower Motor Resistor is located on lower passenger side dash and is easily accessible by removing a few screws. Installation can be completed in under 20 minutes and you can save hundreds by doing this repair yourself. Only fits models with MANUAL AC controls and without rear A/C vents in the center console.
Do you need a blower motor resistor harness?
Replacement AC Blower Motor Resistor Kit With Harness – Controls the fan speed in your AC and heating system. If you can no longer adjust the air speed with your AC controls or your AC system no longer blows chances are you need a new Blower Motor Resistor. This COMPLETE KIT includes the Blower Motor Resistor and New Wire Harness.
Why is the blower motor relay not working?
As I understand things – the blower motor relay acts as a switch completing the electrical circuit between the battery, your fan switch, the resistor and the blower motor. It operates when both the ignition switch and fan switch are in the on position. When this relay goes toes up – then nothing on the circuit gets power.
Why is my heater blower on my RV not working?
Some blower problems are the result of a bad resistor but if the blower isn’t working at any speed then that would be unlikely. In my case it turned out to be the relay but on my rig finding that relay was a PIA (ended up being attached to the radiator housing hidden under the chassis battery). Good luck.
