Most likely the whole dash carrier I would have to look it up but more likely then not. Before you start riping things apart what is the problem your having that you think its a blend door issue?

Heat comes out the passenger side but not the drivers side
Will not switch, Just stays on passenger side

For the dual climate control you have two blend doors with two different vacuum actuators controling it with two different temp sensors for each side so its more then start tearing stuff apart.I also posted how to retrive codes thats are starting point let me know if you have any codes.

Thank You,
Will try to get codes first.
Fan controls has button for up or down, not dial. Will this proceedure still get the codes? Do not get F or C flashing on display.
