RE: Hot E28

	Tony - 

	Only the center vents in an E28 blow cooled air. If you open the
center slide control, you mix outside air with cooled air. The coolest
air will be achieved by closing all the slide controls, and turning on
the AC.

	The heat from the steering column is a mystery. I found that
there was a rubber plug missing from the firewall, and that allowed
outside air to come in from the engine compartment. I replaced the plug.

	I've posted problems about internal heat in my 87 535is before,
but I've 
	discovered more sources of internal heat lately.  Usually after
driving 
	for about 10 minutes (or 5 minutes on highway), the steering
column 
	becomes extremely heated, so hot that my knees can feel the
heat.  The 
	panels around it are fine, but the steering column itself is
really hot.  
	Another source of heat is the fan that turns on when the AC is
on.  This 
	is the fan that's below the temperature controls and behind the
ashtray.  
	When the AC is not on, it emits heat.  Of course when the AC is
on, the 
	heat goes away.  Lastly, the lower vent blows out heat when I
turn on 
	the fan even with the temperature set on 67.  I tested this by
closing 
	the top and middle vents and just letting the lower vent blow.
It seems 
	it blows out heat regardless of the temperature control.  I know
setting 
	the control on 67 won't actually give me 67, but I don't expect
it to be 
	as hot as 85.
	I'd appreciate it if I can get some help.  Personal emails and
postings 
	on the digest are all welcome.  Thanks.
