---------- FOLLOW-UP ----------

QUESTION: It is 2001 Chrysler town & country van with flex fuel engine.
He pulled out the a/c clutch relay and clutch doesn't release.
it just keeps pumping and building pressure and frost on a/c lines. He lives in Florida so can't visit your shop. Do clutches sometimes stick and can they be released?
Thanks,
Rick

Answer
unplug the connector at the compressor  then see if u have a a wire issue  like a short to power where it not suppose to have one. most of the time the clutches will not work at all  I have not seen one stick and stay on. When was the condensor replaced any way?  oh and  in 11 years I have not replaced an evap in an RS mini van yet. The condensers always leak at the pass side lower end.
