You are in the Volvo XC90
What is this discussion about?

My wife once left the car key in the ignition of our 2005 XC90 2.5T. (Engine and power were off, just not pulling the key out.) The battery drained and the car would not start the next morning. Called the Volvo emergency service who sent a service truck within minutes. After jump started the car, the guy said to let the engine run for an hour to recharge the battery, and then go to the dealership for check up. We did just that, but the service department in the dealership did not do anything. They said that as long as the car started with no program and there was no warning or error message in the on-board computer, everything is fine. That was well over a year ago, and the recharging of battery appears to have taken care the problem.

You might Incidently put your headlight switch into Parking mode, and have your parking lights on overnight.
I've done it a couple of times.

Yeah, she might have. The service guys said that some kind of electric or electronic stuff would still be on by leaving the car key in the ignition. However, it is hard to imagine whatever that was would drain the battery overnight.
#987 of 1505 2004 2.5T FWD, 63k miles---a few questions
Mar 11, 2007 (8:20 pm)
Hi, I'm new here. I just bought a (used) 2004 2.5T FWD XC90 with about 63k miles on it. I had the 60k mile service done on it and it checked out great. It was kept in beautiful condition by the previous owner.
I've only owned it a week and am wondering about a few small things: I just noticed a humming/chiming/whistling sound when I turn the car on. It is constant. Kind of like a very distant hum that mimics the "door open" chime. Also, I noticed that the air is "always on" and I'm not sure if this is how it is supposed to be. I can always hear the air system even if it's completely off. I didn't notice this the first week or so of driving it but I thought that maybe it was because I always had the music on.
Another question I have is about the heating system. The air doesn't get "hot" until it is at 86. It is warmish but definitely not hot until cranked all the way to the right hand side. Is this normal? It works, but...not really well.
I LOVE the car, just want to know about these issues. Thanks!

um... there is a button to turn th AC on and off... it stays on all the time so that the car can maintain whatever temp you set it to automatically... BUT, if you want just the heater, turn the ac off via the AC BUTTON lol... you're heating conditioned air... and killing your mpg a little bit.
Mar 12, 2007 (10:59 am)
I probably didn't explain it very well--I know where the AC button is, I have it off unless I want to cool the car or am defrosting the windows. The heater, though, doesn't really get hot unless turned all the way to the right.
What is more frustrating is the constant buzz and feeling like the air system is on even when it's not.
Is this just normal for a Volvo? I'm sure the low buzz isn't, as it would drive people nuts! But maybe I need to not worry about the air coming through the vents (when I close the vents I don't get air but can still hear the system).
I took it to the dealer today to deal with a few recall issues and a rear bulb...they'll listen to the air system at the same time.

I think it was the Parking light.
My battery was drained in 3-4 hours, when I accidently left the headlight switch in Parking position at Mammoth Ski Resort. I went back from the slope for lunch, and could not get my car going. Had to search for the jumper cable, etc., etc.
I do not believe that anything is on, when you turn your car off, even if you leave the key in the ignition.
Other possibility is the engine cooling fan. It stays on for some time, if engine is hot. And if your battery is already weak, it can drain it out. It has happened to me on my S80 after 3.5 years of service. I just replaced the battery, and everything was OK again. However, there could be a problem with the fan's relay, so I will ask the dealer to check it out.

Do not listen to this advise!!!
The system is smart enough, so it does not cool and heat at the same time.
The AC dehumidifies the air coming in. Windows will be de-fogged my faster and stay clear, if you keep the AC on.

The system actually control the temperature of incoming air, so if the temp. control is set to 72, the incoming air, once desired temperature is reached will stay at 72.
The buzz is not normal, probably something is loose in the dashboard.
#993 of 1505 one more question!
Mar 12, 2007 (10:05 pm)
Is it normal to hear the fan on after turning off the car, removing the key from ignition, etc?
Not a big deal but I noticed I could hear it whirring for a few minutes after I turned it off today.
It that is normal, I won't worry about it.
