Since January 2001 I have a V40 1.9 TD (115 HP). It has ECC and Aircon.

Despite that in rain or cold wheater (especially with 1 or more passengers

in the car) I cannot keep the innerside of

the windows clean (damp on it).

I've seen a note from Volvo at my dealer that this problem is known and is

due to a software bug. As far as I understood,

they do not intend to improve this.

The solution they gave in this note was to use the defroster for a couple of

minutes. I tried this a couple of times and it is

only a temporarily solution.

Putting the airstream to the front windows and the fan on 3 improves the

situation a little bit for the front part of the car.

Has anyone faced above mentioned problem as well ?

I used to have the same problem with my 2001 Phase II T4 until I got the advice to keep the air vents in the mid console closed and the ECC on auto. It's actually in the users manual if you look for it, and it works just fine.

Good luck!

I have a 2000 V40 2.0T with ECC and don't have that problem at all.

The only ECC software problem I have heard so far (but perhaps others here know more) was about th evaporator freezing up in warm and humid conditions. A software update fixed that.

You are sure that the re-circulation is 'off'? Perhaps it's stuck closed? Do you hear a sound difference if you put the blower on '4' and press the re-circ button?

Re-circ should only be used for a little while (5 to 10 minutes), or you will see the inside of the windows get wet as the humidity from the breath of the passengers gets recycled over and over again. The A/C will try to dry it, but it may not cope completely.

Unless you live in Arizona or something where it's so hot outside that the A/C can't cool the air coming in from the ouside enough to keep it cool :-)

Are you keeping the A/C switched to 'on' in 'auto' mode? Should pretty much always be set to 'on'. That's also stated in the owners-manual. If you run everything in 'auto' in cold and humid conditions (spring, fall) then you should keep the A/C to 'on'.

If you don't run it in 'auto' then you should put the blower on '3' or higher, select air to foor-area and front window and set the temperature to 24 degree-C or higher. You can leave the A/C to 'off' in that case, but you may get a first blast of humid air as the evaporator dries off.
