Hey and thanks, takin a shot U can help. hot air on a hotter day, tried to add 134 wouldn't go. had a shop check it out. static pressure over 100 on both sides, comp clutch engaged, same psi, no noise, tubes/hoses hot! 1K job they say. another shop check, same thing equal pressure on both sides maybe a bit higher on low side, low side did go down a bit when ac turned on. So had evacuated and checked for black death (debris) ***** and span! They all say a new compressor, drier, etc but won't say that will be all to it! Since the expansion valve is an easy change on these wouldn't that be a first to change?
