Automatic or manual HVAC ?
Air Distribution
The HVAC control module controls the distribution of air by the use of a mode actuator. The modes that may be selected are:
• Defrost
• Defog
• Panel
• BI-Level
• Floor
The mode actuator is connected to the mode door by a cam type linkage system. Depending on the position of the door, air is directed through the HVAC module and distributed through various ducts leading to the outlets in the dash. If the HVAC control module detects a fault with the mode door the HVAC control module will try to drive the actuator for a predetermined amount of time, to defrost, which is the defaulted position for the mode door actuator. When the mode switch is placed in the defrost or defog positions the A/C is commanded on and the recirculation door is moved to the outside air position to help reduce window fogging. A/C is available in all modes and recirculation is only available in the panel and bi-level modes.

On the automatic HVAC the whole dash does not need to be removed !
Caution: In order to avoid actuator damage, DO NOT apply power to the actuator when it is not installed in the HVAC module.
Preliminary Procedures
Remove the instrument panel insulator - right side. Refer to Instrument Panel Insulator Panel Replacement - Right Side.
Remove the instrument panel (I/P) compartment. Refer to Instrument Panel Compartment Replacement.

The dash doesn't need to be removed for manual HVAC either ! Take out the glove box an the insulator panel ! Do you know what the insulator panel is ? There could be a video on youtube ! This repair would only take a half hour at most .

The Acadia's battery is beneath the floor behind the front passenger seat.
Slide that seat all the way forward, then open the rear passenger door. If you've got a floor mat directly behind the front seats, it will have to be moved aside. There is a panel on the floor with one screw holding it closed. Remove this panel to access the battery compartment.

remove any blanking plugs in door trim at arm rest and handles. Remove the window winder . Using a flat blade insert between the door trim and the door and twist until the retainers jump out Repeat all the way around the door. With the glass all the way down lift up the trim and push outwards at the top and it will lift away

You have to remove the door panel to access the wiring harness from the mirror to the door switches

Try spraying contact cleaner to your on/off sw., turn the sw. on & off 5 or 6 times, also try spraying the door button sw.

On the front corner of your Acadia's middle row seats, you will notice a plastic covering - pull on it - the plastic pin holding it back will fall off, and you can then remove it. Now, the bolts that need to be removed to unmount the seat, are clearly visible.
Also, experts recommend that it would be best if the doors are removed to give enough space to manage the task. Removing the doors may take you about 10 to 15 minutes, whereas seat removal can take 20 to 25 minutes.

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door
