ok here it goes got a working 97 2.3 shifts good,cold a/c but..... when i take off my blower on the a/c stops blowing hard untill the truck reaches around 40 mph or i let off the gas,as soon as i do it blows cold and hard again,and if im doing 40 or above and i press the gas to pass someone,the blower goes down again and i cant feel the a/c thru the vents until i let off the pedal back to normal,now i thought it might be vac. related but i checked all i could and nothing seems bad or disconnected,and since it was shifting good i didnt think it was related to the shifting vac. any ideas guys im stumped. thnx b.b
