A couple of point not mentioned by others:
1. Most AC systems (auto, and home) only say they will give 20 below ambiant.
So if you hit 90, then 70 is about right.
2. Do you have the air system in recirc (max) or vented? If not in
the you are mixing ambient with the cold air and decreasing the temp. drop
you can get.
3. How big is you S10. Did they only make that in a standard truck
cap, 1 seat?
I too am very susceptiable to the heat. Over 75, I sweat just
It's not uncommon for me to be outside working in shorts and T
shirt in 40
deg weather. I have a 95 Voyager van with factory 134a. During the
summer, typically in the 90s, I get in the van and am hot. Turn
the AC on
Max and still die. Maybe by the time I get to where I'm going
I've started to
cool off. I've had the system checked several times.
4. Is the 68 deg in the cabin or in the air vents. The plenum temp should get
down to about 40, but the cabin temp will be in the 60s due to head load
from the roof, and glass.
