Anyway, on the SR5, engaging the defroster does indeed engage the AC, and the little light on the AC switch is automatically turned on.
On both Base models, however, engaging the defroster also engages the AC (verified by the tach and by visual inspection of the AC's clutch), but on both of them the little light on the AC switch does not light!
Any other Base owners notice this? If it were just one of them doing this I'd suspect an electrical fault. But with both doing it? (Yes, the little light does come on when the AC button is pushed.)
It's no big thing, just a curiosity. Likely just a minor difference in the code in the chassis computer.

The AC light should stay off in defrost mode (for both base and SR5 models, '96-'00) even though the AC system is turned on. There is a diode in there that keeps the light off but still triggers the AC amplifier to be active. I'm surprised the '00 SR5 does turn on the AC light... Does it still use the lever style controls of your base model trucks? In '01, the SR5's (no more base model) used semi-electronic controls that might act differently.
