when i turn on the a/c the compressor starts an you can hear it running, but the air never gets cold, it seems like it tries a little. but it never comes out cold. it just blows hot air, do i just need freon? or could there be another problem?
air conditioning, compressor works but does not blow cold air, just stays hot on 1999 Nissan Pathfinder
you either need freon or your system needs to be recharged
Take it to a qualified mechanic to check it over, probably just needs to be evacuated and recharged. Professionals should handle A/C, it is not something for a home mechanic. If the compressor is engaging then most likely it's just a low refrigerant charge.
