My interior fan only work on the highest setting 4. 1 2 3 settings do not work. The AC will come on at the 1 2 and 3 setttings but the fan is off untill I turn it too 4 which is blowing me away my AC is super cold/. What is the problem? I have changed the headunit and still same problem.

 

you blower motor resistor is bad.It costs about $40 and can be changed in like 5 minutes. some people on here like to "repair" them and if you do a search you will find that info.
