Why are my fans blowing hot air?
Your fan is fine it’s just the climate and maybe your own body temperature. If the air is hot and humid a fan will blow hot air which blows heat away from your body but air could be hotter that even a fan cannot offer the cooling effect.
Can a climate control fan only blow defrost?
SilveradoSierra.com • Fan Only Blows Defrost, Won’t Change To Floor Or Vent. : Climate Control Fan Only Blows Defrost, Won’t Change To Floor Or Vent.
Is the fan speed control a variable speed?
Is your fan speed control a variable speed or does it have individual set speeds that can be selected for example, Off, 1, 2, 3, and so on? Just the blower is intermittent, not the compressor. Fan speed does not have set speeds, it’s more like a rheostat. It has the rotary control.
What causes front blower to stop blowing cold air?
Outside Temps above 90 degree F. Vehicle is being driven in the city, all systems appear to be normal. Randomly, the Front Blower Motor will stop moving cold air. Rear A/C controls continue to work fine and cold air is blowing out well.
Why does my air conditioner fan run all the time?
A defective thermostatic switch could make the fan run continuously, reducing the coolant temperature to the point where you can’t get enough heat into the interior. If the fan runs all the time, including from a cold start, you might have this problem. Solution: Getting the thermostatic switch replaced should resolve the problem.

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.
Is there a problem with the HVAC blower?
The resistor that controls the HVAC blower motor (front) has failed and I need to replace it. Can … read more I had a problem in which the fan control dial would only work at level 4 (Max level) blowing out the maximum of heat or cooling.
How does a different fan speed switch work?
Those of us that have a discrete number of fan speeds have a set of resistors whereby the fan speed switch selects a different resistor and thus a different fan speed.
