How do you know if your blower motor is bad? How to remove a blower motor? Problems with a blower motor resistor are common in many cars. What is a bad resistor?
In some cars, a failed blower motor resistor can cause a heater fan to. However, other factors can cause the blower motor resistor to fail prematurely.
In that case, the blower motor resistor will fail repeatedly. Around $cost of part,and just phillips screws to remove under the glove box,near the floor. Locate the blower motor resistor. It is connected to an electrical connector that has (or 5) wires. Other plugs in the same area have only 2. Sounds like you already know this.
These instructions should work for many other GMC vehicles such as Jimmy, S10. Remove the electrical connector, retaining screws and the old resistor module.
Swap in the new part and reinstall the screws and connector. Most car manufacturers use a. Refer to the wiring diagram for your vehicle and check for continuity on all three resistors and speed switch setttings. Blower motor resistor has repeat failures. Check for full airflow at the vents.
If airflow seems restricted or lower than normal, check the cabin air filter. When you turn a knob to produce more air flow for heat or cool air, the resistor adjusts the electrical resistance to control the power sent to your blower motor. Since the blower motor and resistor are working almost constantly, it can wear out over time.
The blower resistor is connected in series with the blower fan. This means that the current running through the blower motor , and thus is speed is controlled by the resistor value. The user chooses a suitable fan speed by using a selector to connect one of the resistors in the blower resistor pack. We have the best products at the right price.
A faulty resistor loses power at different positions on the switch. High blower speed has direct power to the motor from the switch. If there is no power indicated on high blower spee the problem is most likely the switch or the fuse.
If there is power indicated on high blower spee but not low or mid range, the problem is the blower resistor. Get a free detailed estimate for a repair in your area. The classic blower motor resistor is a block with various resistors inside it that will switch power to the blower through different resistors based on where the blower switch is placed.
Every time you fiddle with the fan speed of your car’s air conditioning or heating system, you change the current that flows through the blower motor resistor on. How does the heater blower motor resistor work? The air conditioning and heating controls allow you to switch fan speeds — and the blower motor resistor controls that speed once you select it.
