I need to find the blend doors and the blend door actuator, where are these things at under my dash?

Are they relatively easy to get to? I need to verify that my blend doors are working properly before it gets cold again.

I have dual climate controls
Do you
have the same problem?

The blend doors are going to be in the HVAC case, or HVAC module, whichever you call it. The actuators(right or left) appear to be accessible either behind the glove box(rh), or on the left side with removal of the lower insulator panel. Are you having concerns with operation, and on which side?

Here is a guide to help walk you through the repair with the locations of the blend door actors in the diagrams below.

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?

You have dual temp auto climate control correct where it reads out each sides temp settings? For the dual climate control you have two blend doors with two different vacuum actuators controlling it with two different temp sensors for each side so its more then start tearing stuff apart.I also posted how to retrieve codes that are starting point let me know if you have any codes.
