Why does my Dodge Ram fan only blow on high?
This feature is not available right now. Please try again later. If your Dodge’s heater or AC fan will only blow on high, or if it intermittently works on low but then stops, it is very likely your heater resistor. A cheap, easy to replace part, that anyone can fix. Loading…
Can a Ford F-150 blower work on high?
The net should explain how to check the resistance of the contact points once out of the vehicle. And yes, the resistor is bypassed with the fan is on high. You should check and make sure the blower motor is working properly, not jammed, or any obstructions preventing the free movement of the blade/fins.

Are there any downsides to increasing fan speed?
One major downfall to increasing fan speed (above the system requirements) is you will flash heat the air in the house and satisfy the thermostat too soon. The unit would then be cycling constantly and you will not feel comfortable.
How does the speed of a blower motor work?
This means that the current running through the blower motor, and its’ speed is therefore controlled by the resistor value. The user chooses a fan speed by selecting a speed which then connects one of the resistors in the blower resistor pack.

How does a 3 speed blower motor work?
Older style blower motor resistor with exposed resistor elements. The blower motor resistor is what’s responsible for giving you three blower speeds. The resistor block contains three different high resistance coils. Think of these coils like a filament in a light bulb.
Why does my Ricks free auto blower motor not work?
A clogged cabin air filter reduces airflow through the ducts, increases current draw on the blower motor and can cause blower motor resistor overheating and premature failure. If you replace the resistor and it burns out again, check the current draw on the blower motor.
How to prevent repeat failures of blower motor fan?
Plus – Tips To Prevent Repeat Failures! If playback doesn’t begin shortly, try restarting your device. Diagnostic training videos and content hosted by ASE Master and L1 Certified Technicians. Our goal is to teach you ways to be quicker and more efficient in your diagnosis by implementing different techniques and tools.
Why does my blower only work on high speed?
If your blower only operates on its highest speed, chances are you have the series type of blower motor resistor. This is the most common failure mode. To repair the problem, simply replace the resistor block.

Why does my AC fan only work on high?
If your speed selector for your AC or Heat only works on high, or low, or if its missing any particular speed, this video will show you how to fix it once and for all. This is a fix for 2nd generation Dodge Rams (1994-2001-2002 2500/3500) Loading…
Do you need a blower for a new air conditioner?
Having a blower that matches your new air conditioner is necessary to maximize your system’s efficiency, reduce your energy bills, and extend the life of your new system. To see how much it would cost to just replace the air conditioner versus replacing the entire heating and cooling system, contact Service Champions for a free estimate.
What causes a blower motor to not work?
If the blower motor resistors’ internal components fail it may cause the blower motor to malfunction, or not function at all on one or more of the settings. This can also be caused by a blower motor switch, so a proper diagnosis is highly recommended if you are uncertain of what the issue may be.
What are the symptoms of a bad blower motor resistor?
No air from the vehicle’s vents. 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. A blower motor without power will not be able to produce any air pressure,…
What’s the best speed for an AC blower?
Because this process is complicated, working with an expert in AC repair and maintenance is a worthwhile venture. What is the Recommended Speed for Your Blower?
How to determine the speed of an air handler blower?
The first step is determining the current speed of your blower so that you can see if it matches the speed recommended for your model. To calculate your blower’s speed, you will need to measure its external static pressure (ESP). This reading will indicate whether your system has blocked registers or dirty filters.
How much air handler speed does an AC unit need?
For peak performance, most AC manufacturers suggest that 400 cubic feet per minute (CFM) per ton of air conditioning should be used, meaning that 800 CFM should be moving through the evaporator coil for a 2-ton system, and so on.
