First, a big Thank You to Jim Clayton for sharing the important pages!
After a drive through 95-F weather today, I've been giving some sweaty thought to this service advice. My car is in the 650's and I just had a peek in the A/C housing to find that I have the newer-style probe, and it's in the right place on the evaporator.
However, it was sitting about 1/4" away from the coils, making no contact at all. A gentle bend put it in touch with the fins, and a dab of silver thermal transfer grease seemed like an appropriate embellishment.
Tomorrow I'll find out if it fixes the situation.
