Re: Climate control gone crazy (archive)

I recently noticed that when my climate control was on, I had cold air coming out the dashboard vents and hot air coming out the floor vents. Is this normal?
It was terrible today, the first cool day in ATL since April. I had cold air blowing out the dashboard vents (at a fan speed of 6-7) and hot air blowing out the defrost vents (at about the same velocity/volume). They were apparently fighting one another. I tried adjusting the temperature to stop the madness, but that didn't help. I ended up turning the sysstem off for several minutes and then back on (much like when my computer crashes - though I didn't hit my car), which seemed to work.
What's going on here?

I have heard of this before - but not experienced it myself.

Your system lost control of the flap positions.

Re-booting caused it to re-set it's program.

The control of the vents differs depending on whether those flaps are set to "Normal" or "Hot Country" in the "Car memory" function.

Report it - have them look for faults, and also have them do a readout on how your vents and blower are set.

I personlly recommend setting the vents to "normal" - to get "some" A/C cooling out the lower and defrost vents.
I am not sure about the blower setting although it seems to provide more varied speeds when set to hot country.
