If the throttle linkage is adjusted correctly, perhaps the switch is sticking. I would think a spray of electrical contact cleaner should help.
Good Luck. It is too hot already to start having A/C problems!
Thanks, John !!! Yes, I know it's already too hot here for AC problems.

Yesterday, I was waiting in the parent car line for Middle School to let out at 2pm. All of a sudden, I notice the AC was starting to get warm, looked down at the temperature gauge and it had crept up to that mark between 80 and 120 (is that gauge linear? Would that be 100C?).

I definitely need the aux fan to come on sooner. I wonder if I have a "lower" temperature aux fan switch somewhere. Here are the different configurations and what some other forum members have done in the past:

603 Aux Fan Switch (mounts on the dryer, correct?)
Red: 006-545-42-24 (100/110)
Green: 006-545-45-24 (105/115)
Grey: 006-545-61-24 (105/120)
Blue: 006-545-64-24 (105/128)

The first number in parenthesis is the temperature that the aux fan engages at high speed, and the second number is when the AC compresor will cut out.

HitMan_X installed the red one
gsxr installed the grey one

Oh, WAIT a minute. Is the temperature/aux fan switch (green in my 87 Champagne) in direct contact with the R134A ??

Hmmmmm......
