Having problem with my A/C blowing hot air. I don’t know what to do next.

• The compressor clutch is engaging.
• Changed the ac compressor relay, that didn’t work.
• Ac is charged with refrigerant.
• Both fans are working.

Would love your advise on what could be the issue and what to do next.

Thanks in advance.

Good morning,

Can you give me the high and low pressures of the system while the AC is on? You can rent a set of gauges from a parts store if you do not have one.

The other possibility is the blend door. that is common but needs to be confirmed.
