I am wondering if low freon would cause the fan to run without shutting down even with the key off? I believe I read somewhere that low coolant would cause this. I don't have a clue. This is my 1st Volvo. Any suggestions would be greatly appreciated. Thanks

 

Volvo exclusive (to my knowledge) feature called afterblow. The fan will run on a cycle to dry out the A/C evaporator to avoid a mold issue. A quick google search or a search of the forum will confirm this for you.

 

I want to thank you for your input. It just seems to me the fan would eventually shut off. I realized the problem shopping one day. I left it alone overnight and it was still running the next morning. I had an appointment at the VA the next day and it continued to run. I finally unplugged it. Thanks again.

 

Aaahhh. Didn't understand the length of time involved. Many first time Volvo owners mistake the afterblow feature for a fan issue. In your case I would suspect a stuck relay or the sensor that determines when the afterblow kicks in being faulty. I have no personal experience trouble shooting this, but just based on my basic knowledge of electrical systems.

 

Thanks again for your help pkrface. I really appreciate your help. Have a great 4th of July weekend.

 

What fan are you talking about. The fan in the engine compartment or the blower motor?

 

The engine cooling fan behind the radiator. Thanks for your help.. I appreciate you taking the time to look at my post.

 

Replaced Cooling Fan Assembly. I could not just replace the module. Problem solved.
