So after 4 years of never running the A/C (truck sat dead) and the past two years since with no working A/C (no freon in system), I finally broke down and converted to R134. I had a local garage around the corner do it for around $350. All components checked out and the standard drier\oring\fitting changes were made. No leaks yet and there's already dye in the system in case one develops. It's cold. Nice and cold. It's also pretty damn loud for some reason. The problem I'm having is that at idle at stop lights, the temp coming out of the vents rises considerably, and then gets very cold again once I start moving or if I race the engine a bit. Is this normal operation or should something be "kicking in" when I'm at idle? I swear I remember that six years ago, I'd hear something click when at idle and the rpms would actually climb like the idle was faster............
