I think my heater control unit is broken. I am able to get the driver's side heat to work by removing the blend door actuator behind the glove box and turning the white plastic knob that it connects to by hand. This works to direct the heat thru the driver's side system but the passenger side is still cold. I can feel the passenger side actuator if I reach up behind the heater unit against the firewall. No way of getting it off without pulling out the dash.

From diagrams and the fact that there are 2 actuators, I am guessing that these blend doors are independent. Someone else wrote that they had a shop manually open and close BOTH doors without pulling the dash. How? My guess would be that they drilled some sort of access hole and plugged it up after making the adjustment. I'm cold and about to drill a hole in my heater duct so I can get to the passenger blend door. Can someone advise if this will work? or should I try a new control unit?
