Climate control switch only works on high

My climate control switch ony works on high for some reason. It just started doing it. It does not matter if you have the heat or A/C on. Has anyone else had this problem and if so what did you do to fix it. Any help would be appreciated.

It's probably the blower resistor that quit working.Common failure on many GM vehicles.Part #15818910,$42.19(plus tax) if you're out of warranty.

Fan motor resistor is fried. Have the resistor replaced and Do a search on butyl patch water leaks and make sure yours isn't leaking there. If it is, it will just fry the resistor again.
