both left and right temperature controls are set to 64 degrees. left side is very noticably colder than the right side. both at the center vent and each side vent.

what is the cause? servo? and is it a servo buried above the glolvebox.

thanks

There are many servo valves and a control unit, I would suspect the control unit, i had 3 on my 04S since new

The actual valves are not pleasant to work on, why are you setting to 64 ?

Im have the same problem too, when I put the temp to HI for both sides, the left side blows very warm as expected but right side is still ice cold.

This is a common problem with a lot of Cayennes.

I have had the same thing on my 04S coupled with the "gerbils (or hamsters)" rummaging around in there at all times.

Very annoying and expensive to "fix" according to some.

I don't know if Porsche has a real fox for it or if they are just throwing new parts of the same design at it or not.

I have read that some have opened the box and lubricated the actuator arms and that has helped with the noises.

I have this problem also, but only the right center vent is warmer. I am wondering if it is worth the $$ to fix.
