I notice that really only the driver side full heat or full cool click works. Anything inbetween is really nothing special... and the dualzone for the passenger is bunk as well -- more psycological than anything.
The dash climate control (center vent), sometimes works in selecting fresh air or heat, though it's more hot or semi-warm, really (if heat is on).
So is this climate control thing bunk?
I understand that if I set the driver to full cool, there is no heat for anyone else if they try. Conversely, if it's set to full heat, the only 'cool/warm' control is the center vent. What is gradiation between full cool and hot supposed to do on the driver/passenger side?
