You need the dealer consult scanner to readjust the aac valve . It probably is sticking or the air regulator is wide open. the dealer can solve this for you . Its kind of hard to adjust at home or impossible, really. Or you could have a vacuum leak on the intake or ,brake booster hose, etc. rubber it pretty hard at 175,000 miles . Good luck with that .

so the scanner i need is it available any where else cause nearest dealer 60mi away or is there a way to adjust the valve you mention? the throtle body area looks good as do the hoses but i did notice that even though the light for the ac comes on nothing happens no cooling or increase in idle? im not sure but i think someone else talkes about some kind of relay for the ac and idle
