AC problem

[richcarcrazy]

The ac a lot of the time will blow cold on the driveside center vent but not cold on the passenger side. Also the ac in all the vents sometimes won't blow cold at all and constantly vary on how cold it is. What can I check? Is there a sensor for this or a valve or something else?

Do you have the automatic cabin temperature contol feature?? If so, the system will adjust temperature to maintain the set temp.
