You have a dual range HVAC system. It has two blend doors in the HVAC box, and only the blend door for the driver's side is working properly. You will have to troubleshoot, and possibly replace the blend door actuator for the passenger side.
I had the same problem with 2004 Expedition. Changed the actuator for the blend door. This is the one that determines the air temp (cold ---- hot). Purchased Actuator from Advance Auto Parts and installed. I was able to install this pulling out on panel, but it's tight and you will have limited movement and sight. It started clicking again in about a year. After reading other solutions, I realize my Blend Door may be hanging at times. It currently only clicks on coldest setting. If it's moved off of cold a little the clicking will stop. I have also noticed if the setting is not moved in just the spot and you use other electrical current such as windows or brakes it will click because of voltage change and will need adjusting more. I have to adjust this setting in the front if set on front controls as well as the rear if set for rear control. It works fine on Warm or Hot setting. I plan to check door binding when I have time. Good Luck
you need to put gauges on it and see what the pressures are to see if the compressor is working while your waiting for that is the compressor running? is the large ac pipe cold?is the smaller pipe hot?
We had this problem on a 2004 Freestar, and the expansion valve was plugged next to the rear evaporator. The expansion valve allows the freon to flow through the evaporator and cool it. I replaced it and it works good.
