I'm working on a 2007 RR:
A few weeks ago, the climate zone buttons quit operating normally. I can still hear the blower motor running and feel air coming out of the top of the dash, as well as below down by my feet. However, I can't enable/disable the zones using the buttons on the front fascia. All of the lights still iluminate (fan speed ****, zone buttons, max cool, etc.) but do not have any effect.

I am curious as to if anyone else has had a similar issue! Thanks!
