Passenger side stuck with HOT air only

[BruceAlmighty]

A couple of weeks ago I caved, and went to my dealer to fix inoperable "request buttons" ( the little rubber buttons on the outer, front door handles). The solution was a new Keyless Entry Set, and one interior antenna, for about $950. Well, now my A/C & heater blows only hot air from the passenger side. I'm convinced the mechanic broke something under the dash, but am helpless to prove it. I know that the right blend door is not working….according to my local stealership. Part not in stock, so I came home and took it out and cracked it open to test the electrical motor…it works OK. So now, I'm looking for suggestions on where else I should look for the easy, cheap fix…i.e. fuse….or accessible temp probe? The Mazda Owners manual lists the fuses, but several of them are "…fot protection of various circuits."
Does anyone have a detailed list of fuse assignments? Is any of this info available on the diagnosis program hidden in the Nav system?

Thanks.

There was a guy (real specific right?) on here with this same issue a good while back. It ended up being like the flap or something. I think there is some flap or actuator that opens and closes behind the dash and that was the source of his issue, and I don't think it was that huge of a deal to replace.
