I still haven't fixed mine, 'cause I can't seem to find the time to put it
back together. I figured out that the fan was dying, but there may still be
other issues to resolve once I get back on the project. I bought an Audi
Quattro wagon to drive in the meantime, and its ACC works just dandy

With regards to the fan fuse? Easy, it's either in the fusebox or not. If
not, it's unmistakable---on my car, it's a big steel-colored strip fuse with

Crazy how these things go together in bunches. I've been experiencing the
same things that Casey has. A couple of days in the last few weeks the fan
has come on, but it seems if I touch the fan buttons it stops and I'm back
to only forced air. Not a problem on the highway trips, but not good when

Weird stuff, isn't it? Looks like flocking made f
well thats the evaporator, not the heater core, but yes it does need to
be cleaned. They sell a cleaner for that.

Well, I pulled the blower (without the benefit of a manual), and the brushes
and commutator are toasterrific. What's even more disturbing, is the huge
amount of grunge-buildup on the heater core fins. It's almost entirely
occluded any passage of air through there. It looks a lot like the texture
Yikes, Casey. That's a scary photo. And I thought my 300E was bad!
What I did to clean the fins was use a shop vacuum, and a toothbrush,
to scrape and suck away as much as possible, without pushing it
further into the core. I then used a foaming evaporator cleaner from a
local HVAC supply store to

That's certainly one symptom. Full heat can be another.
A failed electrical portion (or wiring thereto) of the
monovalve would do it.

Casey,
Are you getting any fan output at all? If not, I'd check the fan fuse,
which is either a 25A fuse in the fusebox on early 87's, or a 30A flat
strip fuse outside the fusebox on late '87 models. The monovalve and
vac system default into full-heat mode, but if there's no airflow from
the fan,

Jim,
On your website you mention that full heat all the
time regardless of temp. settings, buttons pushed or
vehicle speed could be a symptom of monovalve failure.
I've been expereiencing this for the past two months
and was wondering what else it might be. I was under
the imporession that a fa

Ah yes, I forgot one little detail...my fan has been making some ominous
noises as of late--sorta like a jet taking off. I assumed I'd still receive
some semblance of heat, even if the fan went completely TU. Is there any
reason to buy the fan motor with both the squirrel cages attached,
especial
Bad temperature sensors. You can check them from the right hand
connector on the pushbutton unit. A bad aux pump can cause all sorts
of trouble, too, but shutting off outputs all the time.
Default is full heat with low or no blower and full defrost, so if you
are getting hot air out the winds

Ah, so I'm presently experiencing a complete failure with my the climate
control in my '87 300TD, which sorta sucks...you know, being that it's
sub-freezing and all. Right now I'm getting no heat or fan output at all.
I thought the default failure mode would kick the mono-valve wide open,
