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.

Will a blower motor work without the resistor?

If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed. The heating and air conditioning systems may still function at one speed, however the resistor will have to be replaced in order for full functionality to be restored.

How do you remove an AC resistor?

Difficulty

1. Remove the negative battery terminal.
2. Locate the blower motor resistor on the passenger side under the dash board.
3. Disconnect the electrical connector to the blower motor resistor.
4. Remove the screws or bolts to the blower motor resistor and remove the resistor.
5. Installation is the reverse of the removal.

Is there a way to 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. Move the lead from terminal 2 to terminal 3 and check this reading against specifications. If this circuit is open, showing infinity on the Ohmmeter, the blower resistor must be replaced.

Why is the blower in my car not working?

After removing the blower, you might find a squirrel cage so clogged with debris that the motor can’t operate. In other cases, a broken wire, rusted connections, or a disconnected pigtail assembly might be the issue. If the blower doesn’t receive power, check that the blower fuse isn’t blown.

Can you replace blower resistor?

Remove the screws that secure the blower motor resistor to the housing, and put them someplace safe. At this point, you can remove the resistor from the housing. Put your new resistor in position and connect the wire harness to the blower motor resistor. Then engage the wire harness connector locking tab.

What to do if your heater motor resistor is failing?

If your vehicle is displaying any of the symptoms above, or you suspect that your blower motor resistor may be having an issue, have the vehicle inspected by a professional technician, such as one from YourMechanic, to determine if the component should be replaced.

What does it mean when a blower motor resistor fails?

In our case the ohmmeter shows open circuit, which means the resistor has failed. Sometimes, a blower motor resistor might fail due to problems with the blower motor itself. This means after replacing the blower motor resistor, check if the blower motor runs freely and doesn’t make any noise.

Why is the resistor on my Ford Escape not working?

For example, as you can see in this photo, the blower motor resistor in this Ford Escape has failed due to corrosion. If the resistor shows no visual damage, the resistance between terminals must be checked and compared to specifications. If the resistance is out of specs, the resistor must be replaced.
