On my 1990 jeep, the A.C. was working fine when suddenly we noted no more cold air blowing except thru the defogger vents regardless of vent lever handle position. then noted that the cold air did blow strong thru the dash vents when throttle was let off at speed, i.e. at increased engine vacuum the vents did work. when throttle was opened and accelerating, the vents shut again, i.e. poor vacuum level.
thus it appear there is an issue with the vacuum operated vents. on first glance, no signs of busted hoses or vacuum canister.
wondering if there is a common failure point(s) where I should check first?
thanks!
