Why would the blower and compressor work fine on an 1997 Acura 2.2 CL but the air conditioner not blow cool air prior to this happening there were no signs of it being low on frion?

If the blower and compressor are functioning but the air conditioner isn't blowing cool air, it could indicate a refrigerant leak or a problem with the compressor itself, such as a faulty clutch or internal failure. Additionally, issues with the expansion valve or a clogged condenser could restrict the flow of refrigerant, preventing the system from cooling properly. Electrical problems or a malfunctioning pressure switch could also disrupt the cooling process. It's advisable to have the system inspected for leaks and proper operation.
