Sorry to bring this old subject up.
But my 2003 4runner driver side has only warm/hot hair blowing. Passenger side is blowing cold air.
Now, from what I read and googled, It sounds like its the air mixer servo (blender door?) is the problem...
But others have suggested checking the freon levels.
Now if it is the servo, since its hot on the driver side, should i check under the driver side or passenger side dash??
Kind of strange for this to break... I wonder if it has something to do with bringing my 4Runner to the mechanic to change the cabin air filter a couple of weeks ago.... Also the big white plastic thing (Cabin Filter Fan??) is starting to make more noise.. before it was silent but now there is a noticeable sound coming from it especially if i turn the fan all the way up.
Last things mechanic did:
Change Cabin Filter
Air Filter
Oil change.
