Greetings -

My wife's R52S Convertible is having an interesting issue and I'm hoping I can get some thoughts here as I have never encountered this before.

As soon as you turn on the car her high speed fan comes on and it will continue to run until you shut the car off. This is not dependent on the A/C being on or the car being hot. Both her low and high speed fans do work when I supply them with power, and her power steering / and PS fan work as well. I have checked all the relays and none seem to be stuck and all the fuses look good as well.

Thoughts anyone - I'm stumped on this one.

Thanks,
Chris

 

Low coolant levels. Top off and check for leaks.
