Car Blower Not Working On All Settings

Blower motor does not work on certain settings Another common symptom of a faulty blower motor resistor is a a blower motor that does not function on certain settings. Another symptom of a faulty blower motor resistor is that the blower motor cannot operate in some settings.

A C Blower Problem Jefferson Talledo S Blog

One of the first symptoms of a problem with the blower motor relay is a blower motor that does not function at all.

Car blower not working on all settings. On all systems a failed blower motor is least likely. This will cause the blower motor to operate incorrectly or not at all in one or more settings. If a cars blower motor doesnt work at all there are several components to be checked in the system.

Many many times a car or truck will come into the shop with the customer complaining that their blower motor doesnt work or only works on high speed etc. That means a trickle out of your vents instead of the rush you asked for. -replace your blower motor.

If your cars blower has only 4 or 5 different speed settings it likely uses a simple electric resistor to control the fans speed. Nay sugesstions on why fan does not work on settings 1 2 or 3. If the resistor fails generally the blower will only work on select speed settings.

The ac heater fan only works on selector switch setting 4. It is very likely that the blower. It is the blower motor.

I am pretty sure that it is not the relay since it is working in every setting but high. The resistor limits electrical current so that the blower operates at the correct speed. This one has been a big issue over the years.

Firstly remove the glove box by taking out 5 screws 2 underneath and 3 on top BLUE circles. I own a 2005 jeep liberty. I would check the blower switch to ensure that the contracts for the high position are closing.

What is happening to them you ask. Not including the gentle breeze from the off position. In a situation where the motor doesnt work on any speed the most likely causes are.

Blower motor doesnt work in certain settings. 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. Blower motors generally dont fail out of.

Remove the glove box and look for the wires connected to the heater control module RED arrow remove 2xTorx head screws holding the module in place Remove the connector block. If the blower motor. If there is power on one end of the blower fan fuse but not the other then the fuse needs to be replaced.

When it does happen youre left with a miserably underpowered heat or AC system. Check the fuse for power on both ends using a multimeter. If it works on some settings.

Get a new resistor here. The lower speeds are accomplished by running the power supply through various resistors that drop the voltage which makes the blower turn at different speeds. The blower motor resistor or blower module gets hot as it powers the fan so often times they can burn out causing certain speeds of the fan in your car to stop working the fan can be stuck on one speed only work on high speed or not work on any settings.

Blower motor does not work on certain settings Another common symptom of a faulty blower motor resistor is a a blower motor that does not function on certain settings. This is usually the case after a blower resistor failure on one or more speed settings. Do not do this- if your heat or ac is not blowing AT ALL.

A blown power supply fuse a bad motor ground connection bad motor speed control module or a failed motor. One of the most common problems with an automotive climate control system is a lack of blower pressure or no blower at all. In this video I show the quick step by step process on how you can fix the interior blower motor not working on number 1 2 and 3 speeds in this vehicle whic.

As the relay is the switch that supplies current to the blower motor if it fails internally then power will be cut off from the blower motor circuit causing the motor to no longer function or blow any air from the vents.
