My 75, my 79, and my 88 do not do that. Still have full control over speed. MAX A/C is the same as regular A/C except it is in recirculate mode. Withthe cappy 134 it's always set on max except when my wife over comes my nasty start and smokes in the truck. Then I roll down her window and put it on regular A/C so it draws from the outside and doesn't circulate the smoke into the blower box.
