Cause it was installed wrong

heating and cooling fans are generally one and the same. changing freon doesn't always fix the problem... did you have the system pressure checked for leaks first.
Second determine if the vents are opening properly (switching from heat to cooling) basically when you change to cool it closes air access to the heater core.

Sounds like the air "blend" door might be inoperable. This door opens and closes a specified amount to regulate the amount of either cooled or heated air, as requested by the climate control unit. If the door is continually in the position which is bypassing the heater core (cold setting), the air will not get warm regardless of the condition/operation of the heater core. I'd suggest having this component checked.

The problem is a bad transistor in the resistor module located in the air duct behind the glove box. Just replace the whole module. Mine was only $17 and a ten minute job.

I just replaced mine and had the same problem. If you look at the new one, you should find a small hole at the base of the metal tube. Using a mirror, I located the same hole in the one in the valve cover and inserted a pointed awl into it and was able to pry it out. Do it slowly since you are prying against plastic. When inserting the new one, I found that it should not be inserted as far the original one was and has a gentle snap.
