The vent fan running all by itself is a cabin ventilation system feature that controls the humidity level in the car. Not to worry, the gremlins have not taken over the car.

Hey, here are a few bits of info that helped me, I've owned and loved 3 Volvos myself and they've become "the family car." First, the bad is that, provided you take the Volvo path, be aware that repairs do cost more. The catch though, is that, in my experience, they require much fewer trips to the shop. On top of this, the cars computer system seems to provide ample warning as to when something's going to go. Any V70 you buy (N/A or Turbo) is going to be a 5-cylinder, telling the difference between a 2.4T and a T5 is simple, the car's insignia will have either under the "V70" in the back. About the cost, 14,500 seems a little steep for a '01 V70, I'd expect to pay that much for a T5 or an AWD... Look around a little before buying. overall, the second generation V70's are strong cars, they look as though they'll be replacing the reputation of the previous 850's. I might also add that NEVER, EVER have any of my three Volvos left me stranded, my most recent V70R (1998) started in -35 the other day. I hope my ramblings will help you make a good decision!
**V70R AWD = Love

You do realize that you're responding to a 4 year old post?

Hi,
I just bought a Dec 2000 XC V70 and same vent fan going off out of the blue. So you say this is normal? I was afraid it would flatten the battery one day. What I did to stop it was unlock the car, started it and turn it off. Then it stopped. So its a dehumidifier that is part of the volvo feature?? Wow what technology then !! Cheers

The way I understand it this is a feature which is designed to dry off the evaporator coils and the entire sytem which collects and drains the condensate water from the a/c system. This reduces the growth of mold in the a/c system.
Try it and see how long the fan runs. If it would run and not shut off, then this would drain the battery, but probably you would find that it shuts off in a few minutes.
What some people used to do was to turn off the a/c condenser (but leave the fan on) about 5 minutes away from final destination to allow the evaporator coils to warm up and shed all the water. Presumably this would expell all or most of the water from the air handling box too. But the Volvo automatic system may do a better job or at least an acceptable job without the operator having to go through this.

Thanks mate. I am glad it was a special feature and a good one at that. I live in Sydney and always have the AC on. I will monitor the fan next time it comes on after I park it in the garage. My previous cars would normally leave a pool of water after the AC is turned off. This is my first Volvo so still learning. And its a damn fine car too and you could say I am now a Volvo convert! Its just that the first time it happen I thought it was an electrical fault somewhere that started the fan. Thanks again mate it is appreciated. Cheers

If this system is working as I think, you will still have a puddle of water and in fact it should be a little larger due to the fan expelling all or most of the water on the a/c evaporator (i.e. cooling) coils and in the condensate collection system. But it would probably not be noticeably larger than without the system.
I don't know if this is true, but I have seen it written on this site that the cars come from the factory with this system disabled by software and it is up to the importer or dealer to enable it. The story is that some US dealers neglect to do this and so the feature is never operational becasue the car owner isn't aware that it should be there. But why this feature would be disabled at the factory is not clear to me. . .

Hi mate, thanks again for the info and will see how big a puddle I get when I get home tonight. Which model Volvo do you own? Like I said this is my first one as I have always own Australian or Japanese cars and this is my first Euro product. Have always stayed away from them due to maintenance and ownership costs. But this one came along too cheap to refuse($12k below local market value!!) and I figured I have nothing to lose in the short term. But it has changed my perception of the Volvo and it is a damn fine car to drive. The fit and finish is just excellent and for its age it is drives better than my 2 year old Holden as the Volvo has 161000kms on the clock but feels and drives like a new car. Credit to the previous owner who'd serviced it and God knows what it'd cost him as it was always by a Volvo dealer! Cheers

Mine is a 2004 V70 US base model with 5-spd auto as the only extra. It was a hand-me-down from my wife who moved up to an XC90. I gave away my beloved 1991 Dodge Spirit (100 hp, 5-spd manual) to a good home. I had owned the Spirit for 16.5 years.
My V70 has the naturally aspirated (i.e. non-turbo) 2.4 L 5-cyl rated at 168 hp. It was also serviced at the dealer under the 3-year free maintenance deal then standard at the time of purchase. It's got less than 40 000 mi on the odo (64 000 km).
It's got great highway fuel economy--30 to 34 mpgUS (equivalent to 36 to 41 mpgUK and 7.8 to 6.9 L/100km). But this good fuel efficiency comes from low ground clearance and was apparently partly due to the OE tires being of low rolling resistance. The first highway trip I took after I replaced the OE tires I got only 29 mpgUS (35 mpgUK). I have scraped bottom on some rough roads I have gone on.
Your XC70 has considerably higher ground clearance than a standard V70 and AWD too. I assume it has the turbocharged 5-cyl rated at about 210 hp. So it will not match the fuel efficiency of a standard V70, but is a more rugged vehicle.
In the late 1960s I lived in Fiji for two years, worked for Australians, and got plenty of time in Australian cars of the day. A 21st century Volvo is a far cry from a 1960s vintage Australian or US car.
