That happens to me in my '03 Ram, and Nella's 2000 GMC van. Sometimes I get so cold, I stay in the roundabout for a few laps just to get warm again!!! It's been happening for years in my vehicles, but I thought it was just me!!
Same thing happened with my '06 Ram. The door in the ac/heater box broke and it got fixed and think it's doing the same thing. I hear something thumping down there as the AC compressor kicks on and off.
