Mode door actuator for vent problem, temp/blend door actuator for passenger side. Fix your town on your posting, it says Potwin Ks.

First time on this site. I was hoping it would only b one actuator but I had a feeling it was two. R both of them on passenger side? Hard to change?

Not really. The mode is fairly easy beside the gas pedal. Temp for pass is harder. Have to get to top of heater box with the dash out of the way.

OK last question. I'll start with mode since its easier and I need it more. Is the drivers temp actuator by the mode? If they r I don't wanna take out the wrong one. I looked up there and thought I seen two different actuators

Sorry I have a cold not thinking to straight. Watch them and change the driver temp and see which one moves and the other one is the mode. I think the mode is the one closest to the dash.
