You need to first check that you do not have any vacuum leaks and then check the a/c / heater door operations, if all are working then its possible that you have a slightly clogged heater core.........
Dual Zone Climate Control: -It is possible with dual zone climate control that every passenger in the car can have separate air conditioning temperature.
Inside the passenger side tire...
It is for dule zone climate control
Actually, I have a 2002 Ram 1500 Sport (new body style, 2nd/3rd gen 'not sure which') and it has dual-climate control. I've also had a 2000 Grand Caravan that had dual-climate control as well.Answeryes starting in 2008 model year Answeryes starting in the 2008 model year If you have two temp controlls, then yes you have dual climate control.
Not sure what you're asking, but dif this is happening all the time, you might have a dual air control system. You can adjust the temp for the passenger and the driver, and the control may be faulty.
Maybe because your climate control system needs to be repaired....
The heater on a 1999 Caravan doesn't have a heater valve. The temp is regulated with a blend air door that is controlled by the body computer and climate controll head.
Could the heater door actuator be bad? What is the cost to replace? This Grand Prix has a dual-zone climate control and when the AC is on, the passenger side vents often change to heat when the control is still on cold.
because someone was fiddling with the passenger climate control and now that baffle has stuck in the cold position . I had a 1997 buick lesabre which had the climate control functioning until a friend started adjusting it a few times then it became stuck in the cold position but only for the passenger side It is likely a mechanical bind in the baffle .
Up under the passenger side plastic protector - almost behind the glove box. You will see the air tubes & wires running into a black box there - that is the climate control module.
When i disconnect my battery and reconnect it and then turned my heat on it works for a minute. And then it seems like it makes heat on the driver side and air-conditioning on the passenger side. It has climate control for the passenger.
The powertrain control module is one of many electronic control modules on a 2003 Dodge Caravan.
