Why does your 2004 dodge caravan cool on passenger side but not drivers?

Answer 1

Many modern vehicles have separately controlled temperature zones (driver/passenger/rear passenger). The two front zones are usually controlled by two sliders one immediately above the other (top slider for left side/bottom slider for right side) on the center console heater/ac control pad. For both sides of the front to be cold, both sliders must be slid right. For the driver zone to be cold and passenger zone hot, the top slider must be to the right and the bottom slider must be left, and so on. If the problem doesn't appear to be related to the slider control position (as described above), then the slider control may be faulty, the air duct damper it controls may be faulty, or the air duct may have become blocked or disconnected. Also check that the vents in the dash have not been closed off. If the vehicle does not have separate temperature control zones, then most likely either the air duct has become blocked or disconnected. Also check that the vents in the dash have not been closed off.
