Okay so I have a 2007 Hyundai Santa Fe. The passenger-side AC blows cold air but the driver side AC is blowing hot air what’s going on?
Does it have separate controls for passenger side and drivers side temps? The most logical problem would be in the zone temp blend door controls. And you need a technician who knows these systems.
