Hi I am trying to find the engine compartment fan relay for my 1999 cab 996 2 wheel drive.  I can't find it behind the back seats under the carpet as the convertible top is there.

 

My engine fan is not coming on.  The fuse is good and the fan works.  I am guessing it is the relay?

 

Does anyone know and maybe with pictures?

 

Thanks

Chris

On cabriolets, the number 2 relay panel is mounted to the rear of the roll over protection frame.  You need to put the top in the "service" position to gain access to it.

Thank you for the quick response and you are correct.  I had to call Porsche and speak to a tech.  The relay seems fine.  I should have taken a picture for the next person.

 

Any idea when the engine fan comes on?  The engine is running around 180 and still no fan.  Does it have to get very hot before the engine fan comes on?  Any insight would be appreciated.

 

Thanks Chris

The engine bay fan rarely if ever runs.  There is a set of parameters.  I'll try to find them and post.
