Hi,

I need to confirm. Are you referring to the mode door actuator? That is the actuator which determines air flow direction.

If that is what you are referring to, yes it will need removed. Actually, the manual indicates removing the IP (instrument panel) carrier. I have done it without. Lower the co here are directions for replacement. The attached pics correlate with the directions. The last pic I attached shows location of the actuator I'm referring to.
