No, I will do so this weekend. Your kind of temperatures are not imminent up here so I'm in no great rush. I checked to see if the air stopped flowing through the centre vents when I'm driving when I turn the system off, and it does stop. Whatever that means.

I checked while driving yesterday and the air temp went down to 49F at a steady 2100 rpm. Is it reasonable to expect low 40's ?


P.S.
Found the thread. Thanks!
