My car has been throwIng error 2600 With message 'Temperature flap servo motor rear right'. It is a 4 zone climate car. Recently found out that if I have heat blow into the car, the rear center vents do not blow warm air out of them, even if I put whole system in mono mode (entire car vents blow same temp air out of them).
So I suspect there is a problem with a flap controlling how much warm air is getting into rear of the car.
Based on that, have some questions:

1. Is that temp controlling flap located at front of car or in center console facing back seats?
2. If front, how hard to get to?
3. If rear, how hard to get to?
4. Anyone know p/n & price for the component failing? Really interested in resolving after Christmas break.

My car is 05 CTT.

Appreciate help. Thanks.

 

Does anyone have a link or info on removing rear driver trim to expose the rear Ac units? That is what I have to remove to get to the servo motors for inspection. Thank you.

 

Getting ready to tackle this job. Wondering if there are any refreshed DIYs to gather as much intel as possible. '04 Cayenne TT hvac is on the fritz to say the least. Any help is appreciated.
Thanks
