I have a 92 Buick Century that has been converted to R-134 refrigerant. The car has a lot of miles but is in decent shape and is a solid farm/work car. The issue with the A/C is that it works fine when the RPMs are up but at idle and slightly higher it does not cool. What has me stumped is even at idle the clutch on the compressor is engaged and it is turning without kicking in and out like you would expect to see if the freon was low. It will put out cold air within seconds of revving it to about 1500 rpm and works fine at highway speeds. I have not had many vehicles with air conditioning because I tend to drive old, worn out stuff but here in hot, humid SE NC it is a wonderful thing from late March to November. Does anyone have any ideas? I have talked to several folks and have gotten a lot of head scratching. Does anyone have any ideas? I would greatly appreciate the help.
