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. 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.

Another symptom of a faulty blower motor resistor is no air from the vehicle’s vents at all. Power to the blower motor is fed through the blower motor resistor, so if it fails or has any issues power can be cut off to the motor.

If any of these resistances show an open circuit, then the blower resistor desires to get replaced. Know what fee you should pay to get your automobile constant. The average cost for a blower motor resistor substitute is between $80 and $150. Labour costs are envisioned among $35 and $80 even as elements are priced between $50 and $75.

Where to check the blower motor relay on a Chevy?

Thankfully, it is fairly simple to tell if the relay is malfunctioning and to install a replacement. The blower motor relay is located in the under hood power distribution center and is simply labeled “Blower.” It will only take a few minutes to inspect and replace the relay if necessary. Open the hood of your Chevrolet vehicle.

Where is the blower control switch on the dashboard?

The blower control switch on the dashboard controls the circuit flow of the blower motor to adjust the voltage from low, to medium, to medium-high, to high. When on high, the circuit bypasses the blower resistor.

Why is my blower motor not working properly?

This is a classic blower motor resistor problem which is common on older cars and trucks that use manual fan speed switch controls. This problem will also occur on climate control systems when the speed controller has burned out omitting full power to the blower motor. This can also occur with the ignition key off.

Where is the blower motor under the hood?

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.



How to notice bad resistor in Toyota blower or fan?

How to notice bad resistor in Toyota blower or fan. Issues in fan or blower speeds. – YouTube If playback doesn’t begin shortly, try restarting your device.

How does a relay work on a blower motor?

Finally, with the fan switch on the highest speed, the fan motor is receiving system voltage (14.5 with the engine running). Some systems will energize a relay when the switch is set at the highest fan speed. The relay then closes its contacts, feeding full voltage to the fan, because a relay can handle the current better than the fan switch.

Where is the resistor on a Toyota Camry?

The resistor should be off to the side connected to the same group of cables that connects to the blower motor. To remove it, simply disconnect the cable harness then remove the two Phillips head screws. Then you need to wiggle it out from the compartment. Figure 1. Blower motor resistor is to the left of the motor.

How do you replace the blower motor on a Toyota Camry?

Once you have this panel out of the way, you should easily see the blower and the blower motor. The resistor should be off to the side connected to the same group of cables that connects to the blower motor. To remove it, simply disconnect the cable harness then remove the two Phillips head screws.

The blower switch and its gang of resistors are wired so that when the blower switch is set at the lowest speed, the maximum amount of voltage is dropped and the least amount of current is fed to the motor because it is passing through an entire series of resistors – for our purposes we’ll say there are three resistors.

Resistors have it rough. They always have electricity flowing through them, and the voltage can change sharply as you adjust the strength of the blower fan. If a motor finds it harder to move because of jamming or worn bearings, it can raise the resistor’s temperatures to dangerous levels.

What kind of resistor does a heater blower use?

Types just controlling the fan speed generally just comprise of a few wirewound power resistors (or one resistor with a 3 or 4 windings), which have the effect of regulating the motor speed by reducing the voltage available to the fan. These types always include a thermal trip, which will permanently blow if the rated temperature is exceeded.

Find the blower resistor and detach it from the rest of the circuit, Once the resistor is positioned and detached, it is often possible to say whether or not the resistor has burned out or not judging by simply looking at its condition. A burned out resistor needs to be replaced via the correct alternative.

CASE 2: All circuits tested had continuity where indicated in the test steps. This is good and is the correct and expected test result that tells you that the blower motor resistor is OK and not the cause of the blower motor speed problem. If your pickup’s blower motor resistor passed this continuity test, you can stop here.

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.

What usually happens when the blower resistor assembly fails is one of the resistor’s wires burns ‘open’. So, it’s a good idea to remove it and visually check that both resistors are not burned ‘open’. If any are, then there’s no need to do the continuity tests below since you’ve found the problem.
