Did the 134 conversion back in 99, ac has been blowing warm for past year decided I was going to fix it. I bought a recharge can and filled but the ac compressor is clicking, no cold air blowing. As the compressor clicks the rpms go up and down, I hooked up a gauge too and pressure goes up and down with clicking. It is fully charged. I really don't know much about AC system so any help would be greatly appreciated. Yes I did a search under this topic before posting so save that bit of wisdom for yourself-I also checked out article on regal web by Jim t-maybe I missed something. Thanks
