No Heat - 1990 300SE - PeachParts Mercedes-Benz Forum

Help! I get only a trickle of heat with low fan and EC setting. Using the full fan or auto setting just blows lots of cold air. First MB so I am learning. Any recommended places to troubleshoot? Thanks, Joe

Try searching the forum with mono heat valve. There are many simular posts with the same results, you need a new mono heat valve insert.
