Been ignoring this issue for a while but it's been annoying in the cold
weather. The center dash vent always vents cold air even with the heat on,
this is not normal is it? Should I be looking for a cracked vacuum hose
behind the dash or is there something else that can cause it?

That problem is very expensive to fix. You should sell that car to me
right now!!  :-)

Seriously, is this your first Classic 900? That is one of the great
features of the Classic 900.  You can close the center vent if you don't
want the cold air.  However, you can use the other vents to keep you
feet and body warm - and have cold air directed to your face to help
keep you alert.  Does this car have a working AC system?  If so, you
would have noticed this is the primary vent for the AC.  Again cool air
can be directed to your face to help keep you alert.  I miss this
feature as well as the big front windshield when I drive other cars . . .

This is a really good feature. I miss it since I got my 9000.

It really does help keep you alert when you're tired but you have to have the
heat on to keep you from being frozen.

I have no idea why it's been discontinued.

I still don't consider it a good feature. It would be if it could be turned
to warm air, but freezing cold air blowing in in the winter is *not*
something I find pleasant.

I agree.
This time of year I always have a cold right hand. Left side is OK as I can
direct the warm air flow to my left hand on the steering wheel.

Four options
1. As stated before - you can close the vent
2. Re-direct the vent
3. Wear gloves (a good one since the steering wheel is not heated)
4. All of the above

Or just drive the Volvo on cold mornings and have nice warm air blowing on
both hands...

I love the C900, I really do, but this "feature" has to be the most silly
design decision on that car, all they'd have had to do was provide a warm
vent on the passenger side of the steering wheel and I'd be happy, one more
vacuum flap and a bit of ducting is all it would take to be able to choose.

Does anyone know how the 240 produces heat so quickly? It is great, but
the Volvo is rear wheel drive.  The C900 does much better on snow and ice.

Dang, I know I can close the center vent, but I like to have a vent on each
side of the steering wheel blowing on my hands to warm them up in the
morning, oh well. Yes it has AC but it doesn't work, that's still on the
list.

Absolutely.  It's a design feature that I sorely miss with my 9-5.  Didn't know
how much I missed it until I got back into a c900.  The idea is, cold air
in our face keeps you not drowsy.  Toasty warm with cool air in the face works
very well, and I wish I had a way to do it with the 9-5.

Guess what? My 528 has it! In fact, you can choose between cold and warm
air on the centre vent (independant of the rest of the temperature
controls). I choose cold, because like you I like the combination of
cold air in the face + warm surroundings.

(grmpf...)

But we never disagreed on the design and engineering of those cars, it was
the attitude of the people that drive them that give the brand a bad name.

As before, I know exactly what you're saying.

I don't drive when I'm drowsy unless I absolutely have to, and if I do I
just crack the window for some cold air.

James,

Look at the heater distribution diagram. There are 2 heat selections (on
my '91 at least). The one which is just a down arrow is heat only and no
center cold bypass. The one with the down arrow with the small block
above it is cold air in the center vent. This is in the owner's manual,
though they may have changed this around over the years.

And here, I thought my issue was solved!!!

I've got a 1998 9000CSE.  It blows cold air (even in winter), unless
you set the temp to HI.....  Then, you get way to warm...

I noticed that the cabin air sensor fan is rubbing and will be repl
it...  

Any other ideas???
