Blend door Actuators

I have searched and not come up with anything. How many blend door actuators does my jeep have? One person told me 2 and another said 3....



Thanks

Directly from the FSM...


*****
BLEND DOOR ACTUATOR
DESCRIPTION
The blend door for all models is actuated by an
electric actuator, while the AZC system uses 2 separate
actuators to allow the driver and passenger to
select individual comfort levels.

*****

To finish that statement: The manual system uses 1 actuator for the blend door and it is also electric but the manual system also uses 2 vacuum actuators to control the heat/defrost/floor doors (aka mode doors) and 1 vacuum actuator for the recirculation door.

The AZC system has a total of 4 electric actuators a) blend doors (2) b) mode doors and c) recirculation door.

That would be correct. The electric one was the blend door and two of the vacuum actuators were on the drivers side of the HVAC sub assembly connected to a bunch of levers - those were the mode doors. And the third one was attached to the front passenger side of the sub assembly - that was the recirculation door.
