I own a 02, W163 with heater problems “82K”miles. It is running fine except heater started to blow cold air. I read threads about actuators not working correctly. The AC always works and gets cold. The heater on the other hand starts OK then blows cold air. I already check & replaced anti-freeze, replaced water pump & thermostat (3 hr job). I checked actuator motor behind glove box (working as planed). :surrender: What is my next step? Any good advice is greatly appreciated.
