Hi all, I have a 2002 Phaeton DP, and the dash air has never been cold...only mildly cool. I know that is subjective, but for a comparison, the a/c in my 2009 Ford F-150 runs twice as cool as the P...

Once the engine is warm checking the outlet air temp is not going to tell you much as the heater may have hot water going through it. Checking the temp in the first couple minutes will. If the heater hoses in the dash are only warm it will be defeating the AC. Putting a manual shutoff valve in a line is the easiest solution if the electric motor is not shutting the water flow completely.
I rarely have to run the generator and roof ACs BUT I have a shutoff valve and I bypassed the defrosting relay so my compressor runs all the time. Taking the plug off of it and putting a fues in the plug is all it takes. In the East when the air flow decreases I shut the AC off for five minutes to let it melt the ice. Out West I rarely have to as the lower humidity takes longer to ice up.
