you have a short somewhere it kills the battery after sitting all night make sure no lights are staying on for example you glove box light if it doesnt shut all the way light could stay on and you dont even no it.

TURN OFF IGNITION!!!!!
Look under hood and take off the cover on driver's side electrical box aft of air cleaner. Find the ECM fuse and remove it for a couple of hours.
Alternate is to undo battery ground cable in trunk for a few hours.it is off until the computer sees the problem again. so it there is something that needs to be fixed then the light will come back on

Not True. I have a 2004 S60 and a std features is that the blower motor will run from 10 minutes to an hour after the engine has been turned off, This is to dry the evaporator in the dash and avoid musty odors.

If it drains your battery dead there are possible issues; 1) a weak battery that needs replacing or 2) a faulty power stage/transistor unit ont he blower fan.

The transistor unit has power and ground and a digital signal from the control unit. When the transistor sticks, the the blower will not stop when the ignition is turned off.

If you are talking about the thermo electric cooling fan, its operation is independent of the car's electical system. It is switched on and off by the engine temperature. When you park, the engine heat soaks upward to heat the thermostat turning the fan on. It will run until the engine cools down and the thermostat switches it off.

is this a t6? if so yes. turbocharged engines have more horsepower than naturally asprirated engines, a turbo charger works like a supercharger by forcing more air into the intake, while a super charger is usually belt driven a turbocharger is exhaust driven, it will be located in the exhaust pipe or exhaust manifold and is turned by exhaust gases passing thu with the opposite side connected to the air intake pipeing, some have the intake air piped thru a intercooler which is mounted in front of the radiator(cooler air is more horsepower)
type 2002 s80 volvo in your search bar and you can find a ton of info

Weell it sounds like you have the days old problem Pepole dont know how to look after there cars.
The muck you still have in the engine isent doing it any good and so you have to get rid of it all, as its in the engine block and is got to go ,,so drain a little of water out and put in 1/2 a cup of washing up liquid in the radiator and start the engine and let it get hot and take the reves up to 1000 rpm now and then to keep the water going around the system, after about 1/4 hr turn off,,stand for 10 minutes ,,and then remove the cap slowly and then take off the Bottom hose and let all water out also take off Top hose at the engine end and put the house water hose in the top and turn it on till all water comes out clean. Then put hose up into the bottom hose and do the same again ,and the same in top again.Now with a clean engine you can do the same to the new Radiator and wash out all gunk .then check the thermostat and make sure its 100% (any doubt through it out) and take note how it comes out so you can fit a new one the same way,
Now refit both hoses and fill with coolant or antifreeze and TURN on the heater to hot before starting as you also have to get out the air from heater when it was drained and you will trap the air which might cause you code problems..
But now try service light reset
1,,Turn Ignition to Number 1position.
2,,Press and hold "day counter"reset button and turn
ignition to II(second) position,hold down for about 12 seconds.
3,,Afterservice light flashes,release button,there should be 2 beeps confirming reset was successful.
Let me know how you get on .. Ron

find cooling fan relay and replace it

disconnect the battery for 5 minutes or use a scan tool, the scan tool is prefered method.

IT SOUNDS LIKE A PROBLEM IN THE ACCUATOR MIGHT NEED ADJUSTMENT OR PROBLEM IN THAT CIRCUT
