My air conditioning on my 89 190E w /2.6 enging stopped working today.
My wife had the car today and said it was working fine when she went into a store. When she came out no AC. I set the temp all the way down until it locks in like the manual says to do, press the button for cooling, press the AC button, fan speed on high and nothing but hot air. I can hear something engage when I press the AC button. Motor slows a bit. Please help as I have no idea where to start looking!!
