If it includes vent location, it's most likely the AC Logicon.  If it's heat isolated, it could be just the air mix motor.  Resoldering of the AC Logicon is pretty straight-forward, except there are a LOT of soldering points inside the unit - concentrate on the main harness plugs and the faceplate IC board.  Removal of the unit from the dash is a bit complex, especially for the first timer.  If it's just the air mix motor, it's a remove and replace affair under the dash.

1) You need to remove the plastic cover on top,center of the dash; remove the single bolts/screw under it - you should be able to remove the metal panel now  Be warned, the plastic vent pieces are going explode and turn into tiny pieces of plastic when you distrube them.  Once the metal panel is removed - you'll see the plug in the center, mounted vertically.  Unplug and pull through...
2) Some say you can actually snake you hands from under the dashboard to remove the plug.  I have never done this myself.
Otherwise, there's another option - pop the AC logicon open and unplug the wiring harness from the IC board.  This leaves that harness inside the car, and lets you take the rest of the AC Logicon with you...
Once you get the AC Logicon out, concentrate on the main wiring plugs, where they meet the IC boards.  Also, redo ALL the solder joints on the face plate IC board.  This will solve the problem 90% of the time.
