could be one of two problems either the switch for the fan motor or the motor itself u would need a 12volt test light to check ground one side light and touch the switch connector wires one by one until light comes on this is the main line then turn switch to the 1st speed u should get a light on another wire if switch is working repete for all speed selection if it works then the motor is bad

2002 Dodge Stratus heat/air blower motor only runs on high #4 setting


this is an indication that the blower motor resistor is bad and needs to be replaced. the system is designed to always work on high if the resistors go bad.

Kia blower motor


Not sure I follow your question. If the blower motor runs at high speed on all fan settings, there could be a short in the controller. The fan control and ac-heat control are separate circuits in the controller.

2006 silverado 5 speed heat, the high speed is not working. I do have the 4 lower speeds


The switch, high blower speed relay or the wire harness at the blower motor has gone bad. The highest setting 5 has no resistor, so the blower runs on high but the high current flow ends up burning up the switch's contact on that setting or the relay and may be the resistor wire harness at the blower motor has gone bad. Common would be the switch it self, if the switch is good. Then it's going to be the blower relay or wire leads at the speed resistor by the blower motor under the glove box by the passenger leg compartment. Keep me posted, be glad to help you get your Silverado running 100% again soon.

What's causing my 2005 E-250 blower motor not to work.


does the motor not work at all or only on high setting? if only on high setting, i would recommend replacing the blower motor resistor. if it does not work at all, i would check the blower motor fuse first, if that has power, i would unplug the blower motor, key in run, and turn the fan on, then check for power at the blower motor connector, then check for ground, if both present, then replace the blower motor.

Heater blower only blows on low


This could be a few different things:

1.Check the power and ground connections on your blower motor, corrosion can cause high resistance and a slow blower speed.

2. Check your available voltage at the blower motor on the different settings. it should vary with high supplying 12volts, make sure to do this check with the blower motor still plugged in.

3. Connect the blower to a 12v power source and see if it runs at high speed.

If all else fails i would check your resistor pack, i would not suspect this because when it fails you usually just loose all speeds except for high, but it could happen.
