I have a strange problem in my heater / AC on Cayenne S 2004...
First in the morning when I head to work, the fan does not blow air at all.
Not even if I put it on MAX manually or anywhere in between.
After a couple of hours or so, standing in the parking lot, the fan starts working when I start the car again.
When it starts working, it works the whole day thru. No problems. But the initial startup seems to be the problem.
What can be the cause of this?
The car works otherwise 100% but the heater fan issue is truly annoying!
Any help / ideas would be highly appreciated!
