A potentially forgotten fuse is designated as "MODULE 6," which is a 7.5A fuse. The description is so ambiguous that it may have escaped your notice. This is located over your left knee.
Nonetheless, this fuse is not exclusive to the rear air system; so, if it were malfunctioning, you may encounter many other concerns, including one that is certain to be present in your trim level, the "Front Seat Warmer Control Module." It may be an inappropriate time of year; nonetheless, are there any concerns about that?
