Lately i've noticed that my a/c on my 190e 2.3 1987 wont blow cod air. There are three
buttons to control the temp on this car,one is for the recycling of air the other is the a/c button and the other is the i believe heat button but im bot sure.
Now when i depress the a/c button nothin happens, infact the car gets real hot.When i depress the the heat button the car surges and it beins to get cool but not cold.
with that button depessed it will blow cold while the car is not in motion.When i begin to drive it seems to get warm. I dont understand. Can u help?
I checked to see if it was a fuse but its not. So what could it be.?
