now that i have it starting <new relay & glow plugs> am having trouble
getting heat to the cabin
thermostat is fine gage reads 80C
air has always blown out of the dash so i close it off with the slides
in the winter.
the door is open by the foot peddles
<propped open> it will blow warm air but not hot till i turn the car
once restarted it blows hot then cools a
bit once you get it up to speed.
is there a damper door that mixes the out side air with heated air & if
so where is it hiding?
i don't want to pull the console off as it's an 82 and god knows what
the auto speeds work & the AC in the summer is fine as the mono valve <i
am guessing> closes the flow of coolant when the dial is turned down to
the blue section
and the rear dome lite cover . does it just pop off
there hot but will check any way.
it seems like after a min or 2 the air cools
also on the hottest setting with the fan
on low it stays hot.
makes me think its mixing cool air with the hot.
any repair books i can get?
will buy one
the case, minus a few cans!

My understanding was this pump is only to help cool the vehicle during
hot soaks (ie the car is shut off)?
Some people seem to eliminate or bypass this aux. pump...
Don't know for sure, but hoping T.G. or someone with more
knowledge(then me) can explain this.
The aux heater pump is there to circulate cooling water through the
heater core when the car first starts up. The idea is to get heat to
the cabin faster. From what I've seen on my 300SD, it only seems to
make a noticeable difference if it's real cold, the car is started and
instead of driving off, you wind up either idling or moving slowly.
Otherwise, as the engine speed increases to normal driving speed, the
aux pump really isn't needed and it shut off after the coolant reaches
a high enough temp.
After I bought this car, several years ago, I had problems with the AC. What
I found was enough to piss off the pope. The local "Foreign Car Experts" had
fixed a broken control valve by wraping a rubber band around the flap arm.
When the rubber band broke, .... well you know the rest of the story.
