HVAC problem - Passenger side vents ice cold air, driver side vents hot air




315 000km (about 195 000 miles)
When I put the AC on full blast, the 2 passenger side vents will blow ice cold. However, the 2 driver side vents will blow much warmer air. Has anyone belt with this issue? Now, I'm not very familiar with the HVAC system in cars. Could this be a low refrigerant issue? No CEL or codes whatsoever.
Thanks for your help/suggestions.
