Where is the blower relay?
The blower motor relay is generally located in the under-hood fuse box or in the under-dash fuse box. A blown fuse can mimic relay failure. A failed blower motor switch can also give many of the same symptoms.
Where is the blower fan resistor located?
It's located inside the dash, often on the opposite side of the steering wheel or inside the engine compartment on the firewall. A blower motor resistor or a blower motor control module is the part that controls the speed of the blower motor.
Does a blower motor resistor have a fuse?
A fuse is often located on the resistor board. The fuse only protects the low and medium blower speeds. High speed will still work if the resistor fuse is blown.
What is blower resistor?
The blower motor resistor is responsible for controlling the blower motor speed. ... The change in resistance controls the current through the blower motor, which in turn limits the speed that the blower motor spins at.
What does a final stage resistor do?
The final stage (or blower motor) resistor controls the speed of the blower motor in your heating & air conditioning system. Faulty resistors can cause a list of erratic issues, from the fan running when the car is off, to only having one fan speed available.
Where is the blower motor fuse and relay?
The blower relay is located near the front of the fuse block and is labeled "Blower." Inspect the center of the relay. If the metal rod inside is broken, the relay will need to be replaced.
Where is the blower motor switch?
The blower motor is the electrical switch on the interior of a vehicle that allows the driver to control the vehicle's heating and air conditioning system. It is usually built into the the same control panel that houses all of the AC system controls, and is labeled with numbers and symbols to indicate blower fan speed.
What relay controls the blower motor?
The blower motor relay controls the current used to power the blower motor, and is subject to the constant on and off switching. Over time, it can eventually wear out.
Is there a fuse for the blower motor?
Many vehicles have two fuses for the blower motor, one in the interior fuse block and the other under the hood. The blower motor is usually under the dashboard on the passenger side.
How do I know if I need a blower motor or a resistor?
Typically, if the fan will work on some speeds but not on others, the resistor is suspect. Okay, let's say there's no melting going on, but your fan doesn't work on all speeds. Typically, if the fan will work on some speeds but not on others, the resistor is suspect.
Why does my car blower fan not work?
If little air is coming through the vents (hot or cold), then it could be because the blower motor for the fan or a switch or resistor that controls fan speed isn't working. Another cause might be that the electronically controlled “blend doors” that direct air flow are stuck or broken.
How can you tell if a blower fuse is blown?
How to check the blower motor fuse? With the fuse box located and the blower, motor fuse identified, go ahead and remove it and check the filament. If it's broken, the fuse is blown.
How do you check a blower motor fuse?
Use voltmeter or ohmmeter to check for a blown fuse. If you find one, replace it. Start car and see if blower motor works. If fuse blows again, check for loose circuits.
Where is the fuse for the blower motor on a 2004 Pontiac Grand Prix?
The Pontiac Grand Prix has a blower motor that is regulated with a fuse located in the fuse panel inside the glove box.
