05 No Ac Air on Driver's Side Vent

:screwy: O5 Buick, Terraza will not blow AC cold air on driver's side. I believe the problem may be the blend door actuator or blend door. Has anyone experienced the same problem.

Does anyone know whether the dash must be removed to replace the blend door actuator?:banghead:

i have the same problem and yes the the dash has to come out. I found that if you if you roll the drivers side to cold and then passenger. then roll drivers side back then passenger side it works, good luck
