On hot days when its around 100* out and I turn the car off I notice that the engine fan stays running for several minutes...I assume to cool the engine off. Its an '02 so i've had the car for several years but just this year I've also noticed when its very hot, after I shut the car off, sometimes the fan to the inside of the cabin comes on full blast also. It must come several minutes after shutting off as I've never witnessed it come on, but I have came back to the car (up to 30 minutes later) to have the fan running and blowing outside temp air in there. I have to put the key in the ignition for it to shut off. I'm worried this will kill my battery if I happen to not notice it. Anyone familiar with this problem? Help is appreciated!

 

Nevermind, I found the answer in an earlier post! Looks like its designed to come on to cool the interior.

Glad you found that thread - I think it's actually designed to remove condensation from the evaporator to avoid the possible build-up of mildew. Regardless, it's nothing to be concerned about (although it is concerning to many Volvo drivers).
