The resistor module is easy and inexpensive to replace. Sometimes blower motors and or their resistors will fail and stop pushing both hot and cold air through the vents. 1 blower fan problem. The best setting for diagnosis is fresh air not recirculated with the air blowing out of the center vents in the dash and the ac turned on.

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. If the fan is damaged and does not operate at full power it will not cool down the heat coming from the refrigerant. If you are feeling air and the blower motor is allowing the fans to produce air at all speeds you next want to feel the actual force of the air coming through.
