1997 Saab 900 Q&A

1997 Saab 900 Question: AC is not cooling. Added freon twice. Mechanic says there are no leaks.

Compressor seems to be working but does not cool. -
Answer 1
Not enough info. When the compressor'seems to be working' what do the high and low side pressure readings do? that is only a small part of the diagnostics needed , but would be very helpful info.---You stated r-134 added twice EVAC & RECHARGE each time? or simply adding more to the system the second time? Overcharging can cause no-cool conditions also. -
