Here's an interesting one....
So we took our our "new" 99 Suburban on the family's first "road trip" in it down to Oklahoma City over the weekend. Only 120 miles one way, but it was out of town...
Anyway, over the weekend we had a big cold front go thru and dropped our temps from 100+ down to the 80-90s.
I figured, as thirsty as this thing is, let's run with the AC off for a bit in the evenings. We'll just use my old friend - the vent.
Interestingly enough - on 2 occasions now - after turning the AC switch off and backing the temp control out of the "MAX" cold postion to open the vent, the fan will run for a bit, and then cycle off for a bit, and then cycle back on eventually.
Now, we don't have the temperature set climate control system - it's the 3 knob - fan control, cold to hot control, and "where does it hit you" control set. If it had a temperature setting like my buddy's 2002, I would expect the fan to be controlled automatically, but this....
It seems automatic, but I'm not seeing anything about it in the owner's manual (that I just got via Ebay!). Maybe I'm missing it?
I can force it on by cycling the AC on, but that kind of defeats the purpose.
Any ideas?
After GaryL's cogent description of the "magic mirror" operation, I am quite hopeful someone's seen this behaviour before!
Thanks all!
