Engine lid fan always on with Aerokit?

I own a 2005 997 S. In preparation for a future installation of the Factory Aerokit, I had my local Porsche dealer use the PIWIS tester to code my rear wing to be fixed. It no longer goes up and down. The kit is not yet installed and I have found the strangest thing. The engine lid fan is always on, except when the car is off. It is near 40 degrees here in Nor California, so I know the car is not running hot. The radiator fans at the front of the car are not always on, just the lid fan. I used the harness with part number 99761267071 per the instructions for aerokit installation and the fan continues to operate. I searched and checked all those sensors and grommets and such as per Loren's advice.

So, those with a dealer installed factory aerokit, can you all check and see if your fans are always on, too.

Thanks for the help,

CP

hey CP,

I just had my car at the dealer for the exhaust recall, and had them deactivate the >75mph warning light associated with the fixed wing.

The fan is still on all the time so I am assuming this is normal.

Anybody else with an aerokit ever checked this?

Thanks for the response Raffi. I was beginning to wonder if anyone was going to chime in. I checked with a few others with aftermarket fixed wings and they also have their fans on at all times. This must be a normal occurence. So, I guess that if you either code the wing out or switch the harness, then you will have the fans on at all times while the car is cranked.

thank you

On the 996, it is NOT normal to have the fan on all the time. I am not familiar with the operation on the 997, but I would be very surprised is the fan was designed to be running at all times. It would interfere with engine warmup on cold days. Check your relay's map. If there is a relay for the fan, then it is there for a reason.

The fan on my aerokit only comes on when it is suppose to.

I have an '05 997 w/ aerokit and my fan also only comes on when it is supposed to.
