Ok, just wanted to make sure. on the single zone system. it only has one temp door to adjust temp from hot to cold. on this vehicle, if blows warm on one side, and cold on the other, the only thing it could be is the freon is not flooding the evap core correctly. this is almost always a charge issue. either not charge enough or over charge. I have also seen where dirt and debris plug up the evap core, and not allow the air to blow across all the core fins. by factory spec on a 95 degree day, the pressures should be low side 41-47 and high side 210 psi. here is a picture of the temp door. I think at this point, I would evac and recharge the system to the proper level.

you may have fixed by adding some freon, then you may have just added a little too much. these are very sensitive to a proper charge level. like I said before, 90 percent of the time, it is a system charge problem, either too much or not enough. that is why I think it is a good idea to completely empty the system and charge to the proper level,
