Does blower motor resistor affect AC?
The blower motor resistor is an electrical component that is a part of the vehicle’s heating and air conditioning system. It is responsible for controlling the blower motor’s fan speed. A failed blower motor resistor can cause issues with the operation of the entire heating and air conditioning system.
How do you reset the blower fuse on a HVAC?
How to Find and Reset your Furnace Motor Blower
- Step 1: Turn off the power to the furnace.
- Step 2: Remove the blower compartment cover.
- Step 3: Make sure the blower is completely cooled off.
- Step 4: Locate the reset button.
- Step 5: Press the button in (assuming that this is your issue and that the button has popped).
What does an AC blower motor resistor do?
Blower resistors are resistors which are used to control the fan speed of automotive blowers. The fan speed can be changed either by switching the blower resistor resistance mechanically using a rotating lever, or electronically by the air conditioning system.
How do I know if my blower resistor is bad?
What are the symptoms of a bad blower motor resistor?
- No Air.
- High speeds only.
- Low speed only.
- Fan won’t turn off.
- Blower motor works on some settings but not others.
- Smoking vents.
- Burning smell.
Why is my AC blower not working?
However you want to word it, if your indoor fan isn’t working it could be several things. Try setting the thermostat fan switch to the “on” position. Feel for air coming out of the vents. If it is in the air conditioning mode, check for ice around the evaporator coil and on the refrigerant lines at the indoor unit.
Can you fix a blower resistor?
The resistor module is easy and inexpensive to replace. It’s then typically installed in the ductwork, near the car blower—either under the dash or under the hood. (Refer to a service manual to locate yours.) Purchase a new resistor module at the auto parts store (usually less than $25).
What happens when a blower motor resistor fails?
The blower motor resistor is the component directly responsible for controlling the blower motor fan speed. If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed.
What are the symptoms of a bad heater motor resistor?
Symptoms of a Bad or Failing Heater Blower Motor Resistor. 1 1. Blower motor stuck on one speed. A common symptom of a faulty blower motor resistor is a blower motor that is stuck on one setting. The blower 2 2. Blower motor does not work on certain settings. 3 3. No air from the vehicle’s vents.
What does the resistor on a heater do?
It is responsible for controlling the blower motor’s fan speed. When fan speed is changed via the knob on the instrument cluster, the blower motor resistor changes setting, which changes the speed of the blower motor.
Where is the blower resistor on a 2017 Chevy?
Hit the A/C button, compressor is coming on, so not a low Freon issue. On the 2017, I located the blower resistor plugged into the duct on the passenger side, upper left area of the foot area, was surprised to find out that it could be accessed without even removing the cover for the blower area.
