If it were me, like I have done with both of my 9900's, I would go ahead and replace the evaporator while you have the HVAC housing opened up and since you will already have the expansion valve removed the evaporator comes out super easy.

One thing I forgot to mention, have you inspected the operation of tht Recirc/fresh air door and actuator to verify it's proper operation? I have found plenty of 9900's with broken Recirc doors. The attaching point for tht actuator is plastic and it gets brittle and breaks off allowing the door to fall into the fresh air tunnel. When the Recirc door cannot close properly the hot outside air is being allowed into tht HVAC housing and the evaporator has a hard tg cooling that hot outside air hence the warmer temps from the panel vents. Just a suggestion for you. Let us know what you find.
