I've 2007 XC90 and experience very strange problem. This problem happens to me two times. The 1st time in February '07 when I took my new car from the dealership:-) and 2nd time now, October.
The problem description: All AC control buttons including air flow are frozen. This means whenI press anyAC buttons or even try to change Fan speed they are not responsive. When I stopped the car, remove a key and insert key again and start the car the problem goes away. In other words when I "reset" the car everything works normal.
Of course I couldn't prove anything to the dealership. They justwere not be able to reproduce the problem.
If somebody else experiences the same problem with this vehicle?

I am assuming you have the 3.2 I6 this is a common problem. They may not be aware of this yet. Take it back and have them perform a ccm upgrade. If they dont know about it here it is

CPS Plus, No CCM function after engine start

DESCRIPTION:
Intermittently, The CCM (Climate Control Module) may not function after engine start. No

This may happen due to a fault in the signal communication from the ECM (Engine Control

ignition key is taken out and re-inserted after 10 seconds. To prevent this symptom from
occurring, an improved ECM SW has been developed. Only SI6 engines are affected.
