Anyone? 03 4R AC blows hot on driver side cold on passenger side

I've seen this question posted but no replies on solution. Has anyone experienced this problem and found the fix? My '03 has 115k miles, bought it new and the only problems I have had is with the AC. Had a bad relay that caused the flashing AC light and now this problem that occurred a few days ago...otherwise an outstanding product from Toyota and yes I will buy another when I am able to wear this one out.

I have the same issue. Sometimes the AC light flashes and doesn't work at all. Then it just fixes it's self. Now, like you, the AC blows cold on the passenger side and warm on the driver's side. I with I had the solution.

I had someone on another site tell me it was the air mix servo. There is one on each side and apparently easy to get to but I have not had luck locating yet.
