Steve, Hopefully you remember me. I have asked you tech questions in the past but it has been awhile. Hoping you can help me with this one. My A/C sounds the same and does not increase when I go from Regular to Max. It seems as if I should hear and feel a difference going from regular to max. I have checked a lot of things with no luck. Checked all vacuum lines, vacuum reserve "ball" the flapper door (and arm)behind the glove box. All looks ok with those items. Can you point me out on what else I can try considering these symptoms. Air comes out in correct vents and comes out cold also. Thanks in advance for your help? Kent Buckles
