Why is the heater speed control not working?

Why is the heater speed control not working?

Aircon models are diffrent as they fixed directly in front of the motor on the lefthand side using 1 torxbolt.They also have a 5 pin multiplug where as the standard heater resistor has a 4 pin.This is probably down to the fact its connected via a relay which starts the blower motor at a low speed when the aircon is switched on.

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…

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.

What should the speed of a blower fan be?

Blower fan speeds 1,2,3 packed up simultaneously. Resistor pack is accessible from footwell of car. Remove 4 pin black plug on underside of blower. Then slide and pull out resistor pack.

Why does my blower fan not work on high?

Blower Fan Works on High Only 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.

What do you call the fan that spins the heater?

When the heater or air conditioner in your car is turned on, the fan turns on pushing the air from the car vents. The motor that spins that fan is called a blower motor.

Can a blower fan change speed on its own?

You can have it on auto or non-auto; the fan speed starts changing on its own. Like a ghost is hitting the button, beep,beep, beep, beep, so on and will continue making the beeping noise that you hear when you hit the button until you manual stop it. Than sometimes it doesn’t stop.
