Follow-up: I checked and the 7.5 amp (compressor?) fuse was blown - I
didn't replace it as my wife had an appointment with the dealer the
next day. The repair ticket listed low freon as the problem and no
mention of the fuse replacement. Should I be concerned?

Yep. Perhaps make a call to the service manager and ask the following
questions:
-- Why is there no mention of replacing the fuse?
-- Was there any effort to locate the cause of the blown fuse?
(Hint-- it won't be caused by low refrigerant since the system will
turn itself off in this event)
-- Did the effort to locate the cause include a check of the field
coil resistance as specified in TSB 07-97-003?
If you don't have an account at hmaservice.com, register for one. The
TSB doesn't really say much other than the field coil resistance
specification for several newer models. Regardless, it'll help if
you've read it and understand its relevance. Every single vehicle (to
which the TSB applies) I've encountered with the 7.5A A/C fuse blown
needed a field coil. Typical resistance readings for the defective
field coils were around 2 Ohms.
