Do you have the automatic temperature control system that allows driver and passenger to set to different temperatures?

Is so, a blend door motor could be at issue in the dahs.

If not, it's also possible that the air conditioning system could be slightly undercharged.
ok i was leaning towards a door motor/actuator problem,so tell me how to retrieve fault codes from hvac module.
Iam getting part tomorrow to try .look for answer tuesday11th.
