What causes a Porsche air conditioner clutch to slip?
Clutch turns but slips. If the front hub on the compressor seems to “slip” (we are not discussing the belt here) you could have two potential problems: The air-gap between the faces of the front hub and pulley is too large. This does not happen often on it’s own, more probably if the compressor was overhauled.
Why is my climate control not working on my Porsche Cayenne?
A common problem in the Porsche Cayenne is a condition where the climate control fan suddenly starts working intermittently, only at one speed or not at all. The variation in the speed of the fan is controlled by the blower motor regulator. Once the regulator fails, a single speed fan is commonly the result.
To trouble shoot the Porsche air conditioning system can be simple, then maybe not so simple. And you don’t want to hear the cliche “take it to a qualified Porsche technician”.
Can a Porsche Cayenne HVAC fan regulator be replaced?
The regulator controls the fan speed of the blower motor and can fail after many years of use. Thankfully, replacing the blower motor regulator is an easy fix, usually taking no more than an hour. In this article we will also cover the steps involved with removing the blower fan itself.
