Why did my AC stop throwing cold air?
There are a couple of reasons for ice buildup in your AC — dirty coils or filters resulting in poor airflow, or a lack of refrigerant. If that doesn’t get the unit blowing cold air again, it could be refrigerant levels are low (see below).
Where is the evaporator located on a Porsche Cayenne?
Evaporator: The evaporator receives the cold liquid from the expansion valve. The evaporator is usually located inside the car under the dashboard. When you turn on the A/C fan, it channels air over the evaporator, cooling the air; this air is then blown through the vents of the car.
Where are the air conditioning hoses on a Porsche Cayenne?
Shown here are the low (green arrow) and high (yellow arrow) pressure ports. Unscrew and remove the black plastic protection caps to access the fittings below. If you are using a set of air conditioning manifold gauges, connect the low and high side pressure hoses to each port.
Is it possible to trouble shoot a Porsche air conditioner?
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”.
How do you change the refrigerant in a Porsche Cayenne?
Luckily, replacing and topping off refrigerant is a relatively easy process. Begin by starting the car, turn on the A/C system and fan to full blast, and let the car run for about three minutes. Following the instructions included with the kit, connect a new can of refrigerant to the hose/gauge assembly.

Why do I have trouble shooting my Porsche air conditioner?
For R12 systems, if you see a strong stream of small bubbles you are low on refrigerant. With R134a systems or conversions we are not to concerned with refrigerant flow observed at the sight glass because the flow can be cloudy and little if any (with R134a you are more concerned with pressures and temperatures).
