A/C Only works on drivers side

Yesterday the air-conditioning stopped working on the passenger side of my car. The blower works fine, with the same amount of air flow as the drivers side, but no cool air comes out. Changing the temperature setting has no effect. We were only able to cool the passenger side by putting the A/C on max, so no outside air came in - eventually the passenger side was blowing cool air. The temperature outdoors was in the 70's.

I'm having a similar problem.  I was with out  heat had a clicking noise coming from the dash changed blend door actuator still no heat so I changed the heater control valve have heat only on passenger side only if I'm using the dual setting for my heat if I turn dual off then I get heat to drivers side.  I have a 04 mountaineer 4.0l awd.
