 your posted #'s are NOT right and would normally indicate an undercharge. The real problem is why? Is it leaking?

Hit back my home site or I'll keep at this here - great site. --T

Yes it was leaking the evaporater was replaced .Also the compressor bearing was rumbling. So the compressor and expansion value were replaced along with the receivier dryer. After charging with 24oz. of r134a low side is 80 and high side is 125 I initialy thought the expansion value was stuck open so I replaced it a second time now I am thinking the compressor must be defective what do you think? any comments appreciated!
Thanks
Rick

My chart shows 24oz is right.#s Still off. I'm here most of the time but will mention two A/C only sites for possible more help as you have me stumped.

HTTP://TomGreenleaf.autoACsystems.com and Hit "Cool Zone"

WWW.Aircondition.com go for "bulletin board"


I'm loyal to THIS site but these are A/C only places and might have your answer. Come back here soon if only to say hello! Good luck with the fix,
