Houston we got a problem… Weird heating behavior.
Is there a way to reset the Climate Control? When it is cold outside my car heats up well with both sides blowing hot air. When the outdoor temperature gets to like the 50’s-60’s Fahrenheit. the passenger side then blows out less hot and comfortable air. My driver side switched from hot to extremely cold and both sides are synced to 80f. It’s not hot outside it’s now 60f so why does the passenger side blows lukewarm comfortable air to accommodate for the outside temperature change while the driver side just jump to extremely cold A/C. But if I turn the heat up a few degrees both sides gets back hot like it supposed to? Do y’all suspect the heater control valve flap for the drivers side is defective? I don’t have a coolant leak.

Would need to check actual values but either that side temperature sensor or heat blend flap has a problem.

Same brand so I think that should work, I got one that works with the phone that was like $100. And with Amazon you can always send back.

If you really want to do this you need Xentry and Benz Ninja or you can learn how to operate the Xentry system.
I will say that when the temps go to 50-60 the system really does not know what to do.
I usually keep mine at 75dg in the winter.
Mine heats up so nice when its cold, but when its like you describe the system blows coolish air out and actually makes me chilly.
My S430 did the same thing.....
May be a Benz thing.
