Re: 2001 A/C diagnosis - what does it mean?
MAX ac has to do with the air flow in the cabin ... it is only cabin air being recirculated ... no outside air. The inside fan will speed up on this setting ... has nothing to do with electrics ... just the air resistance being much less when only cabin air is being recirculated.
As far as the radiator fans are concerned; I would have expected the fans to be on hi anytime the ac is on ... no matter what else ... but I'm not familiar with your year model, so this may not be true. But please don't let some intermmitant condition such as burned relay contacts or loose wiring fool ya.
