My A/C has been recharge with freeze 12 and works fine till I go up a hill and give it more gas then it blows hot air until I'm over the hill.

I looked for leaks in the vacuum hoses and have not found any and looked for the vacuum reservoir and cannot find it and maybe someone took it off, might add one but wait till I hear from you. Thanks, Bert

Brett: When you say resevoir, are you refering to the cooling system or the AC? There isn't one for the AC. As far as the problem, is the compressor still cycling when it gets warm?
