Cabin fan runs a long time after shutting off
I think I posted this once before but can't remember.
Our 2002 S60 has a odd thing happen after shutting off the car. The fan that is meant to cool off the cabin after the car is turned off runs a LONG time. Tonight my wife got home from her commute, shut off the car, came in the house and we decided to make a run for some wine and stop off at the mall. We were probably gone an hour, we arrive back home to hear the fan is still running.
I told her to get in the car and turn the key to position #2, don't start the engine and then remove the key. The fan stopped. What would make this happen?

But doesn't an hour seem kind of long?

pkrface is right. It's called Afterblow and is totally normal. Certain conditions, including battery voltage, must be met in order for it to activate.
Just because you came out to the car an hour later and it was running does not mean it was running that whole hour.
There used to be a bulletin outlining the exact conditions, but the site is down right now so I can't look for it.

Yeah I can't remember if it was running when we left. If not it could if started running sometime after we left and had only been running for a short amount of time.
I guess using battery voltage is better than having an evaporator rust out.

I consider it to be over engineering and probably not necessary. I have six cars and the 2002 Volvo is the newest one. The oldest is a 1990 Jaguar. I've never had any rust destroying the system and not had any odd smells. The 95 Caddie will freeze your head off and is all original equipment.
As my wife says -- It is what it is. Nothing I can do about it. My bigger fish is getting the SRS light turned off after I install m newly repaired DIM. UPS tracking shows delivery today. I'm just picturing a match between me and the Volvo dealer.
