Rear AC Making Thumping Sounds when i unlock the door
 

Hello, i am trying to find some instructions/video on how to remove the back panels inside the rear right hand area of my 2013 Dodge Journey SXT. every time i unlock the doors there is a thumping sounds coming from behind the 2nd row seats...

The dealer told me it was the rear AC actuators and wanted to charge me over $900.00 for the repair... I asked what the parts costs were compared to the labor and he told me the parts would be less than $40.00 the rest was labor.

I have looked online for a video of how to remove and expose the back panel, but i am not able to find anything. Does anybody know of a way to remove this back panel and expose these actuators so i can replace them or am i stuck with the dealer charging me $900 to fix this?

thank you,
Fred
