so just this morning i woke up early and it was a bit cold and i go on to turn my heat up and nothing :/ blows cold air... so with that said the thermostat is stuck open am assuming.... and i don't know what kind to get, summer is coming and live in FL... also what is the regular running heat on these cars??? mine is staying on the next line up of 80° and falls down a bar or two goes back up etc...

any help would be appreciated
and any idea were i can source a thermostat other than dealer???

Maybe the heater valve? Here is a link that I found: https://mbworld.org/forums/w211-amg/...ed-advice.html

It's a bit complicate to work on because it such a tight squeez. The valve cost $42.00. If you decide to do it yourself make sure to get cold beers ready cuz you might need it..LOL

I did it myself with no issues at all. Maybe 45 mins. to do. I believe there is a how to on it.
