I have plenty of airflow coming out of the vents.

Charged my SDL up with 134 instead of duracool after compressor swap
this year, it cools down to the 40's. Just put a used compressor on my
85 300D and converted it to 134, it drops down to 38, YES THIRTYEIGHT
degrees vent temp with 85-90 outside temp. I dont think I have ever
seen 134 do that before.
Kaleb and all,
All this talk about temperature drops is irrelevant unless the air
volume is taken into consideration. Consider that an evaporator coil,
clogged with leaves and trash, will naturally exhibit a colder leaving
temperature at your nozzles. So just having cold air will not be
satisfactory if your volume of air is down. Also, when you compare,
you must take into consideration what the inlet temperature is to lyour
evaporator. Here in Phoenix, when I start the car and it is 130
inside, I will be tickled if it comes out of the nozzles at 80 degrees
initially. A 40 to 50 degree drop across the coil is about all you
can hope for with acceptable air volume. If I am on recirc, I know the
air will gradually get colder on each pass that it makes through the
evaporator coil.
I am currently looking at the blower circuit on my 116 after finding
that the maximum voltage reaching the blower is 9 VOLTS, this with the
engine running and about 13 .5 volts at the alternator. Air flow is
way down. I ran a heavy jumper from the alternator block to the fan
connector and that baby really took off. So I know there is room for
improvement.
The servo was bench tested and runs cleanly to the end of travel, both
ways. I suspect the climate control push button switch has begun melt
down and is building big resistance. I think this failure occurred
shortly after I bragged up how good my system was running to JER
Never, ever brag about how good something is working without copious
amounts of wood to knock!
