Hi Folks, On Sunday my son and I went to the local air show for some high-speed entertainment. When we left, I wanted to cool down the '91 Carat as "fast" as possible so opened the doors, cranked the engine up and turned the AC and fan on max. About a minute later I had some unanticipated enterntainment when I heard a pop at the rear of the cabin and hissing sound (not unlike a bicycle tire going flat) for about 2 minutes. Once I assured myself that I really didn't have a flat I guessed that the sound I heard was my AC system dumping all the 134a (yes it was converted by the PO using the kit) into the van. Whatever my van was leaking smelled of rubber - not burning rubber, but just like air that has been in a tire (thats tyre for Clive and Andrew ;-) ) So, A) Amongst other things, I'm an HVAC moron, if you can, and will, help me with this - please feel free to break out the finger puppets. B) Is there a safety relief valve in these AC systems that will go, or am I probably looking at a blown line, hose etc. ? TIA Barry 1991 Vanagon "Sauna" |
