I would imagine icing inside a line
would show an unusually high high-side pressure?
The icing is not inside the line, it's in the airflow path.
If you have enough water inside the system to freeze, you've
got a serious problem!
Airflow naturally reduces when the fan speed goes down, you're

The fact that the compressor stays engaged suggests its not the air temp sender?

With a guage - Low pressure or even vacuum on the low pressure side. On
my Subaru when its evap temp sender wasn't working the low psi side
would frost all the way to the compressor!

Could your temp sensor be monitoring the temperature under the dash, and
shutting down the A/C when it got to be cool and comfy under there?
Maybe a little smoke near the sensor intake grille to see if it gets sucked into
the grille?

On my '95 E300, the AC starts out strong, but after about 20 minutes it
is noticeably weaker and eventually it fades completely away (goes from
very cold to cold to sort-of-cold to ambient).
On my '95 E300, the AC starts out strong, but after about 20 minutes it
is noticeably weaker and eventually it fades completely away (goes from
very cold to cold to sort-of-cold to ambient). AC compressor clutch is
staying engaged.
Could this be a leaking monovalve insert? Next time I can play,
