Heat comes tru passengers side console vents and normal thru drivers side

SOURCE: 2002 Ford Expedition Climate Control System

you have a loss of vacuum. There is a small diameter black plastic tube from the engine compartment that feeds the climate controls. Check at back of control head, or there is a plastic connector under dash were other color tubes join to operate the other actuators of the system the black tube must have vacuum when engine is running. check under hood the black tube is spliced. separate the tube and check for vacuum The tube enters the firewall near the heater hoses.

SOURCE: A/c cold on onside not the other.

sounds like a cracked vacuum line... or a bad vacuum control box getting the settings confused check there first.. (hot air from outside is being forced in on the one side because one vent is open, cold on other then when on normal when both outside vents should be open 2 arent and one is)

SOURCE: air conditioner not blowing cold air

go to a parts store such as Advance Auto Parts or Auto Zone and buy the A/C recharging kit they have with the rubber line and connector that connects only on the side that you need to recharge your system. If you can put air in your tires you can out freon in your a/c system.

SOURCE: 2003 Ford Explorer XLT Air Conditioning vents blow hot and cold

It sounds like the control motor switching from hot to cold is stuck halfway in between the two temp settings. You will have to take it down and replace it, it is mounted under dash passenger side near the blower motor.
