Another AC thread

[haromaster87]

Hey Guys,


So I'm ready to get serious about getting some AC in my 1984 300D. I have been reading all I can about the AC systems in these cars. I can't pretend to understand the system well yet, but I'm working on it. Right now, I'm getting familiar with the engine bay stuff, but I am at a loss with the control components. At this point, I think I'm going to need some advice catered to my situation, hopefully with you guys and some elbow grease, I can get some AC!

So my current system. I have the climate contol style with the dial and the horizontal buttons, like this:

It has the air sensor on the dash as well. Right now, I have all of the vacuum disconnected from the climate control as I did it to eliminate shifting issues. I am aware that I will need to reconnect this and make sure the dash vacuum pods and lines are all tight, correct?

I'm also pretty sure my compressor is shot and that end of the system will need to be replaced. I will probably get the sanden compressor kit from the member on here to replace the compressor and I'll replace the lines, drier and check valve while I'm at it.

What it does now, it blows. It seems my blower motor is okay. When I press any of the climate control buttons, the blower motor kicks in and hot air blows out of the all of the vents. That's kind of where I'm at now.

I'm guessing I need to check out my monovalve too. I see that pop up in a lot of reading.

I know it's not much to work with, but like I said, this is where I can use some help. What additional components are there in the AC system that I need to check? Is there a way to test my control unit? I'm not necessarily looking to restore every function of the climate control. If I could just set it up to blow cold air when one button is pressed, and hot air with another, I'd be happy. So based on what I have so far, where should I go from here?

Thanks in advanced guys!
