No cooling - pressures seem OK and compuressor run 15 Years, 9 Months ago
I recharged my R134A system on a 1993 Isuzu with no cooling. The compressor sounds like it is running, the low side presure is about 75 psi and the high side is about 250 psi. There is no cooling at all.

look for the a/c cooling fan. and make sure you made a good vacuum, at least 30 minutes. if that fails, try changing the dryer and doing a good vacuum.
