A friend of mine has a diesel 1987 sdl and it needed a ac evaporator. So I put the evaporator in and everything went smooth. My problem is that I wen to test the heat and ac and I am having problems. The heat doesn't get hot and only comes out of the defrost no matter what button I use. Now when I kick it over I ac it will work wherever I put it. What could I have messed up??


After messing with it for a
Little bit I couldn't get the blower to shut off no matter what button I hit. I had to turn the key off. Any help would be helpful
