My current car is a 2006 c4s. Recently I have noticed that the driver side radiator fan is running. Now I have noticed that the passenger side radiator fan never turns on. Is there a fan for this side of the car? I have contacted Porsche but haven't heard back yet. They said the trouble light should be on if there is a problem. No problem light, no problem. Sounds like no fan is running to me.

A trouble light will NOT come on if the fan is not working. Yes, there is a fan on both sides. You can pull the wheel, and the fender liner on that side and spin the fan to see if it spins. My guess is it is either seized up, or the shaft has broken.

Actually you may be able to just unbolt the bottom of the fender liner and reach up and spin the fan from undereath (car not running)
