Heater fan works sometimes?
Not knowing what year, make and model you have, I would suspect the heater fan switch and or electrical plug to the switch is at fault.
What could be wrong if the front defroster and AC on a 1991 Chevy Corsica are not working and it seems to be the blower motor because when you turn the setting to heat it works?
Replace your heater selector switch
Why does the fan for heating and cooling only work on the highest setting in your 2001 Mercury Villager?
If the fan in your 2001 Mercury Villager only works on the highest setting, it’s likely due to a faulty blower motor resistor. The resistor controls the fan speed, and when it fails, it often defaults to the highest setting as a safety measure. Another possibility could be a problem with the fan switch itself. Checking and replacing the resistor or switch should resolve the issue.

Cycles it on and off based on attached thermometer setting
2001 dodge 1500 ac and heater flow regulator switch does not work. works only on defrost?
2001 dodge ram 1500 ac and heater flow regulator switch does not work. works only on defrost. How to fix?
Why does your heater ac fan only work on high all of a sudden 92 S10 Blazer?
sounds like the resistor board has blown, on the highest setting it has no resistors, hence the reason it still works
Why does blower for ac heat works on only on highest setting for a 2001 Toyota Highlander?
Sounds very much like the speed switch may be faulty, or the ocntacts need cleaning.
Heater motor only works on high speed in 2001 ford ranger?
Normally when a heater blower motor only works on the High setting, it is caused by a defective Blower Motor Resistor Pack. The fix is to, Replace it. In very rare instances it can also be a defective blower motor speed control switch, but rarely.
Why will the heater in a 1996 Grand Am with 4 pos heater switch not work on HIGH but it works in all 3 other positions?
Your heater switch may not need to be replaced. The heater high position is controlled by a fuse under the hood. Until you find the fuse and replace it, your new switch will not work. JRR.

Have you turned the control from Pilot to On? Have you increased the temperature setting?
What would cause the heater fan rear defroster to not work on a 1991 Chevy caprice the heater fan only works on the highest setting?
If the heater fan on your 1991 Caprice only works on "High" the problem is more than likely the resister assembly in your blower circuit or poor connections at the resister assembly. When the switch is in the "high" position the current does not flow through the resister assembly it flows directly to the coil of the blower relay. When the switch is in "low", "medium 1", or "medium 2" position the current flows through 1, 2, or all 3 of the resistors in the resistor assembly which results in the 3 different lower speeds. Check the resister assembly and replace if needed.
Why does heater motor only work on 4 on 1997 fiesta?
If the heater motor in a 1997 Ford Fiesta only works on the highest setting (4), it is likely due to a faulty blower motor resistor. The resistor controls the different speeds of the blower motor, and if it fails, it may only allow the highest speed to function while disabling the lower speeds. Additionally, issues with the wiring or a faulty switch could also contribute to this problem. Checking and replacing the blower motor resistor is usually the first step in resolving this issue.
