One thing I do know is that refrigeration air conditioning is not as
efficient out here in the dry desert heat. Since the task is to remove
moisture, its hard pressed to find any out here :-) I might guess that
your car has a smaller interior, and is better insulated? <shrug> Just a
thought

When I lived in NJ, I could make it snow in my car :-) Out here, UT,, I
get mostly cool air when the temp hits 100.
