I'm t'shooting a Vissani wine cooler (I believe Danby Appliances is the manufacturer).

I hear the very clear sound of gurgling from one specific location in the back of the appliance. I want to access this area to investigate the source of the noise. The back cover appears to be Plasticore. I cannot remove the sheet metal case nor the plastic interior.

I need to see the refrigerant line in the area circled in red. I prefer not to cut into the Plasticore, since obviously I don't want to nick the refrigerant line.

Feel free to post suggestions on how I should access this area.
