How can I find the correct blower motor relay?
How can I find the correct blower motor relay?
Locating the correct relay can be tricky. Look for terms such as a blower, AC, or cooling fan relay on your schematics to point you in the right direction. Bring your damaged relay with you to the automotive or electronics shop to ensure you’re getting the right part for your blower motor.
Where is the relay on a radiator fan?
The fan relay is often located in the engine bay’s fuse box, but the best way is to check your repair manual to find where it is located. Testing a 4 pin relay is often very straightforward. Remove the relay and give 12 volts to pin 30 and 85. Ground pin 86 and check if there is voltage coming out from pin 87.
How does a high speed cooling fan relay work?
During high speed operation the PCM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. After a 3 second delay, the PCM supplies a ground path for the high speed fan relay and the cooling fan s/p relay through the high speed cooling fan relay control circuit.
Do you need a relay kit for a cooling fan?
A relay kit, our part number CCFKRL, will include everything you need to properly wire up your electric cooling fans, with the exception of additional wiring needed to complete all of the circuits. The first part of the installation is to install the electric fan to your radiator, and remove the mechanical fan.
Where is the fuse on an electric fan relay?
The orange wire on the relay should see a 12 volt signal when the ignition switch is turned on. The other two wires on the relay are the meat and potatoes of the system, with the yellow wire connecting to the battery along with the supplied fuse mounted within 12 inches of the battery.
Locating the correct relay can be tricky. Look for terms such as a blower, AC, or cooling fan relay on your schematics to point you in the right direction. Bring your damaged relay with you to the automotive or electronics shop to ensure you’re getting the right part for your blower motor.
Can a fan be connected to more than one relay?
For smaller fans, both fans can be connected to a single relay as shown above, and the proper fuse should be installed to protect the circuit while at the same time providing enough current to flow without exceeding the fuse rating.
What can a contactor be used for in a starter?
A contactor can stand on its own as a power control device, or as part of a starter. Contactors are used in applications ranging from the light switch to the most complex, automated industrial equipment.
How does a starter work with a manual controller?
STARTERS With a manual controller, the operator presses a button or moves a switch that is integral to the electrical equipment being run. In other words, the button or switch is physically attached to the controller itself, and is not operated remotely. When an operator activates a manual controller, the power circuitengages,
What are the main functions of a starter?
They can also stop them, reverse them, accelerate them, and protect them. Starters are made from two building blocks, contactorsand overload protection: • Contactors control the electric current to the motor. Their function is to repeatedly establish and interrupt an electrical power circuit.
Why does my blower motor keep blowing fuses?
Relays are a vital protection against electrical surges. When the relay receives a jolt of strong current or simply cannot manage and distribute its load, it will send excess current into the fuse. This forces a shutdown which protects the entire system from electrical damage. Thus, blown fuses could be a sign of relay issues.
What do you need to replace a blower motor?
Allen wrenches, a deep-socket set, a small flashlight, and a few screwdrivers might be needed to navigate through the motor’s inner workings. The connector itself is usually a small black box with wires of various colors running from both ends.
What does a blower motor do in a HVAC system?
A blower motor is a mechanism that allows HVAC systems to distribute heated air. This piece of equipment makes it possible for structures of all sizes to maintain a comfortable indoor climate.
Where can I get a blower motor replacement?

Where is the blower located on a Ford Escape?
It’s all jammed up behind the center console and dash. Access to most of it is from the footwells on either side (pull pedal assembly or glovebox and body control module behind that depending on exactly what you want to access).
Do you need to remove dash to remove blower?
Details depend on exactly which version climate control you have. Total dash removal seems only necessary of you must remove the ENTIRE blower plenum assembly (not likely, you need inside of it, not to remove it).
