How do you bypass a blower motor resistor?
Difficulty Remove the negative battery terminal. Locate the blower motor resistor on the passenger side under the dash board. Disconnect the electrical connector to the blower motor resistor. Remove the screws or bolts to the blower motor resistor and remove the resistor.
Where is the HVAC blower motor 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.
How do I test a blower motor resistor?
Place one lead of the Ohmmeter on terminal 1 of the resistor. Place the other lead on terminal 2 and check against specifications. If this circuit is open, showing infinity on the Ohmmeter, the blower resistor must be replaced. Move the lead from terminal 2 to terminal 3 and check this reading against specifications.
Why is the blower in my car not working?
If the blower doesn’t receive power, check that the blower fuse isn’t blown. A blown fuse often indicates an underlying problem, so never replace one with a larger fuse to prevent it from blowing out again.
Why does blower motor resistor keep going out?
The blower motor appears to be defective here. When the brushes wear out the motor draws excessive amps which could cause the resistor to burn out. Before making further replacements remove the motor and check it, especially the brush assembly. This is the most likely reason for the resistor to fail repetitively.
Is there a fuse for the blower motor?
The blower motor is powered by a fuse-like device called a relay. If your heater or air conditioner does not blow air through the vents, this could indicate that the blower motor fuse has probably blown. While replacement is easy, the exact location of your blower motor fuse may vary from vehicle to vehicle. Step 1
Where is the resistor for the blower motor located?
Two individual resistors make up the blower motor resistor assembly on your Chevy pickup. As you’re probably already aware, these resistors are located between the A/C-Heater control panel and the blower motor . The purpose of these resistors is to reduce the amount of the blower motor’s current that’s passing through them.
Could You Tell Me the location of the blower motor resistor?
Find the blower resistor and detach it from the rest of the circuit. For the precise location, consult the repair manual for your car’s make and model. Some common locations are near the blower fan motor, under or behind the dashboard, around the passenger footwell etc.
