glad I could help! saving money and helping people keep their s class w220 on the road is my goal..

Hehe. I try one viewer at a time … thanks for watching

Well. You probably have to check and make sure the ac compressor is activating or not .and then does the engine fan cut on. After that its a good idea to check the amount of r-134 is inside the system.. if that all checks out correctly. You can rest / delete the climate control error codes. And see what happens.. If all else fails. Hooking up an advanced Mercedes Benz obd2 scanner into the car and review climate control data will point out further issues. The computers coding/ algorithms are essential to the operation of these cars .. so be prepared for 👨‍💻.. hopefully this helps you

@@piscatawaymechanic I did everything you said. It has good cold now. Appears to have a small leak. I will watch it this week and see how bad it is and get some UV die . Thank you so much, May God bless you.

сначала надо проверить коды неисправностей. я покажу вам как в этом видео

You should do a fault code check, which is done using the actual climate control buttons. This test will show and issues you are having within the system. I show in the video series. Doing the fault code check is the only way to know what needs to be fixed.

That code. Is ac refrigerant r134 pressure at 0. Could mean your empty on refrigerant need a recharge , or a small hole has developed somewhere in the system ( dye test can locate it) , or your ac compressor is failing and can't compress the refrigerant any longer. Good time to go to the dealership or a good seasoned Mercedes technician.. they can run test with accuracy on their diagnostic tools.

I can try to help u.

@@piscatawaymechanic error 1417 and erorr 1269?

Now im not 100% sure this applicable to Asian or European Mercedes models. But those codes are B1269= communications fault of a/c bus w/ control unit b31/1 (acc multi function sensors) B1417=(left duo valve ) heater valve fault

It looks like code b1256 is bad evaporate temperature sensor .. you could replace it and erase the code and check and see what happens. If the code comes back again or not or if it solves the problem .. because the thermostat will have a obd2 code for it. And the cars temp will run hot or cooler sporadically. As the first sign of an issue

if the codes come back the problem is still there ,so more investigating is needed. there could be broken vent flaps. but check

if u go thru my videos i have one that show how to get any fault codes from the climate control unit. and another with all the available code meanings on another video. if ur here in the (usa 🇺🇸 models ).. thats the best way to start with any issues..

kzfaq.info/get/bejne/f71ld7ejr8qWmIk.html check out my video here. tap the video description box.. where i have listed all of the know climate control codes for the w220. hopefully that helps u.

With these cars You have to go down a check list.. #1 check the error codes coming from the climate control unit,#2.is the a/c compressor working (is the clutch engaging also),#3.is there ac fluid in the system,#4 check for leaks anywhere in the system ..#4 does the engine fan engage,,#5 any blown fuse …. If all else fails , you’ll have to take it to a Mercedes Benz mechanic to have them diagnosis it

@@piscatawaymechanic I just changed the control unit at the top , followed all your instructions, i will check and see if i can find out if the thing needs to be recharged
