A/C and HEATING Problems
#1

Hey guys! I am new here but it is because I have had some trouble with my 1998 blazer. The heating and A/C can only work one at a time. What I mean is that only one can be in the engine at a time. In the fall, I have to take out the ac and put in heating and vice versa in the spring. I do not know why they can't work when they are both plugged in.
