Description of 300CD Climate System

It will be time to troubleshoot my 1985 300CD AC and climate system. My problem is that I don't understand the components and working principles of the specialized climate control system. Where can I find an overview of the system that explains all the components and their function in the system?

Their java app is flaky, but I can get it to work on my laptop.

Post HVAC Fun

What you have is called the 'Klima II' system and it's a pretty good one once it's sorted out .

First things first : ? does the fan come on automatically? or only if you push the far left button ? .


The fan motors are usually dead now, new isn't over $100 or for $15 and a few hours of careful work you can return the old stiff original one back to life by cleaning , installing new brushes (need to be soldered) and properly lubricated ~ most just slap in new brushes and wonder why it don't work right and why it blows fuses every so often...

Fix those two things then look into the monovalve, this controls the flow of hot coolant , you should be good to go, lots and lots of older threads on AC & HVAC repairs & service.....
