1981 to 1991 Mercedes Best Upgrade for the Automatic Climate Control 

Thanks again for looking out for us lost souls that refused to think are cars might be a little obsolete

Just wanted to say thank you for the vast information/knowledge your channel provides about these vehicles while I can still post a comment as many of your comments sections are disabled and I can probably guess why. These videos will eventually become time pieces themselves. Stay blessed.

Great video - I can’t say enough good things about the folks at Klima. I used their parts and know-how to rebuild my old 240D AC system years ago - top notch parts and people, all around.

I’ll never find day where these cars aren’t fascinating to me! Thank you for all you do Kent!

I installed one in my w123 two weeks ago and it is fantastic

The Fuse Holder at 6:28-6:45; protection fuse for your New Climate Control panel very interesting!

Nice info. 👍 The new HP heater valve is going to be a big hit.

Thank You! I’ll look into this klima control and seeing if the local guy knows about this.

Thanks for walking us thru the climate mono valve, Kent. My r107 heater is currently working great, but I’m going to take a look at the mono valve and I’ll know what to do when/if there’s a problem. As always, your enthusiasm for old Mercedes is contagious!

Going to order the klima mono heater valve replacement today. Tired of no or little heat from my 126 300SD 1983. My most favorite car I have ever owned! Will never sell this diesel antique. I love this old turbo diesel, still get 23 mpg with over 300,000 miles. Had to replace the odometer plastic gears, so no telling actual millage! It's a tank, but rides and handles like new. Of course I have spent a lot of time working on this old beauty!

Hello from Wisconsin Thank you for your new video I will definitely get some parts in the near future. So far my 82 300d with turbo @ 260k is working great thanks in part to all your help

I'm so ready to try this kent...

That broken pin at 5:38, I did that. lol

Thank You! My 88 560sl is in need of help. Klima control I’ll look into this.

Nice solution Kent. And you are always laughing in your video, funny. 🤣👍

Thank you Kent.

Thank u Kent

I wish there was an alternative for my climate control and my ignition for my 98 w210 wagon.

... but what an update versus the Auto Temp II systems from 76-81!

Hi Kent

Thanks for the info. I've had my 88 560SL for just over a month and the heat was great. Today about 15 minutes into my drive it quit. When I stopped, I restarted it for the heck of it and the heat came back. This wouldn't be the valve would it?

I've purchased Klima's Sanden Aircon kit to replace the terrible factory air conditioner compressor. They have a high quality bar and don't like Chinese parts. I feel confident they will only supply quality parts.

So 85 380SL. Heat would be fine at startup but fail after about 8 miles. Did some research and thought it "might" be the monovalve, so I put in a rebuild kit. Now no heat at all. Reads 28 volts at the connector, no matter where the temp dial is. Thoughts?

What about an early 1984 wagon, does it use the same Bosh or something else

Hello Kent and thank you for your many videos and advice. I am looking to purchase a true love of mine. A 1983-1985 300D. Do you have anything available?

Of have a question, are in general, the W123 300 diesel and the W126 diesel the same?

Hi Kent my w124 has a delay with the climate control it takes about 30 minutes to switch on have you experienced this problem?

Does anybody make a kit to just install a regular 240d style climate control in dash?? Knobs? Something normal? Thanks

😎👍

Does this new Klima valve work with the w126 windshield heater? Also how hard is it to install behind the w126 300SD false firewall?

Hey Ken, do you work just on your car or would you be able to work on my 1998 Mercedes S600?

MAY FRAND YOU GOIN TO CON VEIINS ME TO GAT .A MARSADAS. IM THE KEIN ABAUT A 420 SL. .ILIK THEAT CAR .IM LOOKING FOR A 1989. .HOUP .I CAN. AFOREIT . TO GADIT AND THEAN KEPEI T GOING . .🤗👍👍👍
