Possible A/C - Vent issue... Insights?
Issue cropped up this weekend while camping.
Pulled into the spot. As I was maneuvering to find the optimal spot I had the vent on (dash vents) to cool off. I leave the engine running as I leveled, put the slides out, etc. When I switched off the engine, a "hiss" or more like very low "AM radio static" sound came from under the dashboard... on the left side, where the back-up camera speaker resides. I checked the volume on the rear camera monitor, it was all the way down/off. The static sound remained for a few minutes and then fell off linear until we could not hear it anymore.
Additional tid-bit: I notice my fan(a/c compressor?) for the vent - A/C comes on every once-and-a-while while driving and the vent A/C is not "on".
Any help/insights would be appreciated!
