Blend door actuator problem

Recently all heat and A/C started blowing only through defroster vents/no air coming through both dash and rear vents. Could this problem be solved by replacing the blend door actuator on the passenger side? If so, how is this actuator accessed in the dash? Appreciate any guidance you can give to solve this problem..

Thanks,
Larry D’Angelo

Hello,

Yes this does sounds like you have a mode actuator that has gone out. Here is a guide to give an idea of what you are in for when doing the job:

Here is the location for your car (below) I have included all blend door actuators for future reference. The first one it he one you want to do. (mode)

Check out the diagrams (below).

Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken

Yes, I reviewed the schematics provided but I am still unclear as to which actuator controls air direction in the cab and the correct part number associated with it? I just want some verbal clarification that this particular actuator is the one to the far right near the passenger window post? I have seen several iterations of this on-line which adds to the confusion. I would appreciate a little more information just to be clear.
Thank you for your assistance.

Hey Larry,

It is the mode actuator that is closest to the gas pedal #7 in the diagrams. Look under the dash on the drivers side about the throttle pedal and you will see it. Move the seat all the way back before you begin. You might need a 5.5 mm or 7 mm socket to remove it.

Ken:

The diagram shows #7 as “mode actuator” - would I not need to replace #8 which is described as the “re-circulation actuator” if my dash and rear vents aren’t circulating air? The diagram is not real clear as to how/where to access #8? Am I correct that the re-circulation actuator #8 is what needs replacement? If so can you please elaborate so that I can replace the right actuator? Thanks in advance for your continued help!

It avoid confusion remove #7 and then turn the system on and work the pivot by hand to see what it does. I believe it is the mode actuator that is causing the problem but this will confirm the issue. #8 is the left side temperature actuator.
