AC/Heater control valve :Lancer 2003 Misubishi

The sliding switch on the console is stuck in the cold position and the knob is pulled off. Use pliers to jiggle the switch as best you can. Feel under the center console and you probably will find the cable that is hooked up to the flapper. You'll know because when you jiggle the cold/heater switch at the upper console, the cable will move slightly. At the hookup of the cable to the flapper down under the console (passenger side) try to work the flapper loose to the open (or close) position. At the same time work the sliding switch (with pliers). The flapper will come loose and function properly. Try not to knock of the AC button like I did in the process. It flew off some where under the passenger seat. I'll find it sometime before summer. Ha.

Replace the knob, this doesnt have some valve you can just change to make it switch,this is a blend door with electrical actuator that moves the door from hot to cold air and also turns on or off ac depending on if that has a separte switch else where on control,you would have to remove the actuator and move the door and then some how jam the door so it doesnt move, i think its easier to replace the knob or use plier to twist the shaft of the control where the knob did.
