Air Conditioner Problems
I have a 98 E320...Recently my air conditioner isn't working properly. The left auto climate isn't blowing cold air. Only the Right side is. Does anyone know what could be the problem?
thanks

Run the diagnostics

post the values 1-8 and the errors.
You either are low on r134a or a stuck duo valve both easy to rectify.
Diy's on www.benzworld.org w210 diy section
Or someone will tell you how to give the duo valve a thunk or add r134a.
Or wait until later and pm me.

Hot and cold
I rebuilt my duo valve (Heater valve in Stealer lingo) due to a broken valve stem with the pop rivet repair (Excellent) idea.
Checked coil resistance across each solenoid 23 ohms, checked voltage 13.2v. Passenger side still 58F drivers side 85F ambient 94F...no change!
Put a shut off valve in the forward upper inlet to the dv coolant supply line to the valve, to stop the coolant reaching the heater.
No change
DTD checks Ok with only E232 pressure switch showing.
Sensor data
1-46
2-38
3-31
4-29
5-27
6-52
7-15
8-60
Any ideas going forward?
