In general that would be a loss of vacuum to controls but confused because the vacuum sources are not where you were working TMK. If you have trouble finding a vacuum break somewhere hit back and let's see what magic we can do, T

PS: I own one of those as a plain C/K 2500 with 5.7 and A/C so I could go look but it's no where near my computer

Sorry I'm lost with this problem. It started right after another repair that would make anyone think that was the cause but might not be.

There are a few MVAC dedicated sites (Motor Vehicle Air Conditioning) sites that may do better that I can myself and NOTE that this is my FAVORITE site but we need to cooperate sometimes.

Http://autoacsystems.com/tomgreenleaf More than just me....
WWW.ACsource.com Nacho there would know in a heartbeat!

WWW.ackits.com

All of these are sign up sites but have the best of the best for MVAC. Hey -- don't get me wrong -- CARJUNKY will rule the web for cars if it doesn't already but if we don't cooperate we all lose!!

Bon chance mon ami, "Good luck my friend" T
