The cooling fan in my 2002 Volvo S60 appears to be stuck on. It's been running for about 45 minutes (although I've tried to restart the car a couple of times in that period, without it un-sticking the fan). I understand it can run up to 6 minutes after the car is turned off; however, it's obvously been much longer than that. My local Volvo service is closed and AAA will only tow me to a repair facility for the morning; however, I'm worried about the fan running all night. I know nothing about cars, except that I did manage to get the hood open. I can feel the cool air from the fan, but can't see any parts moving in it. What should I do?

I had the same problem and it will eventually run the battery down. It is easier to disconnect the power to the fan than the battery post. The fan connector (wire bundle) is just above the fan just aft of the hood lack. It isn't hard to find. There are two very large wires one is red and white wire. Simply release the connector lock by pressing down on the lock and pulling the connectors apart.

Being able to disconnect the fan will allow you to park your car without having the battery drained. Just remember to connect the fan when you are driving the car otherwise you might overheat the engine, especially in stop and go traffic. I did this until I had the time and money to replace the fan assembly.

Basically, there are four things (ECT senor, A/C pressure sensor, ECM, or fan controller) that can wrong and cause this problem, but most likely it is the fan controller itself, which cannot be bought separately. You must purchase the full fan assembly.

The dealers will want over $400 just for the fan assembly, however I have found it as low as $220 on the web. Be careful when you order one to make sure it has the controller attached, as I had found some that didn’t have the controller. I had the same problem and it will eventually run the battery down.
