Where is the blower motor on a Porsche 911?
On the 911s made after 1978, Porsche installed a separate blower motor in the engine compartment to give an extra push to the air that’s channeled to the cockpit. This blower motor is connected to the air intake of the fan through a plastic hose that often develops cracks over the years.
Where are the flaps on a Porsche 911 heater?
Exiting out of the front end of the heat exchangers, the warm air enters what is known as the flapper boxes. These two boxes, located on opposite sides of the car, control the flow of hot air into the cockpit. They have flaps inside that are either open or closed.
When to replace a Porsche 911 heater hose?
If the heater hoses that connect the flapper boxes and the heat exchangers are broken or ripped, then you should replace them with new ones. Be sure that you only use high temp heater hose, as most other ordinary hoses from hardware stores will melt when exposed to the high heat from the heat exchangers.
What was the problem with the Porsche 356 heater?
With some of the Porsche 356 models, there were problems with the European heat exchangers rusting through the pipes. This caused the exhaust to become mixed with the air that was fed into the engine compartment. As a result of this, a few people died from breathing in exhaust gases.
Where does the heater start on a Porsche 911?
If you have an open-air car like the cabriolet or a targa, then you will immediately recognize the importance of having a working heated defroster on a humid day. The source of all this hot air starts in the engine compartment. Depending upon which model and year you have, the orientations of the hoses and blower motors may vary.

Why is my Porsche 911 heater leaking oil?
When the car warms up, this oil will start to burn and smoke, and you can actually have smoke coming out of your dashboard vents if you are not careful. With this in mind, it’s a wise idea to repair all of the oil leaks that might drip on the heat exchangers before you activate your heating system.
