Window Won't Come Back Up 2000 V70

[D.D. Pallmer]

My 2000 V70 (with AWD) has a driver's side window that won't come back up.
At least it didn't for 2 days. It finally rose yesterday. It's not clear why
it stopped and why it came back to life. The car is 6 years old with about
40,000 miles on it. It doesn't get driven all winter (we go to Florida and
the car is up north) and when I got back last week it started doing this.
Also, the electrical "dummy light" on the dashboard was intermittent. I
disconnected the battery while we were away because in prior years it
drained and died.

I had exactly the same happen a few months ago.
I was sat in the passengers seat and operated the electric window to raise
as it was down a little.
To my amazement the window just went down and stayed down.
I took it to a Volvo dealer who reloaded the software £20 UK........ $ 35
and the car was OK and has been since.
This is what Volvo told me, it could have been caused by power lines etc or
a strong magnetic field caused by a such as a mobile phone mast telephone
exchange.
