I spent more than a month on and off researching the issue, buying parts, using different HVAC tools and diagnosing tools, this is going to be a super handy and essential 15 min video for your HVAC system as usually fixing these types of faults is not going to be cheap. I recommend you to watch the entire video and I hope you like it and learn something new. Cheers, Max.
Good info, thanks for sharing. I noticed you are using Foxwell scanner to monitor the AC compressor, can you share which model scanner you used? And is it enough for average diy maintenance on these cars?
Hi Max, wish you can teach mechanics how to fix cars properly! The Zoyi oscilloscope you have, does it export data into laptop? Its screen may be on the smaller side so my eyes may not see clearly. Amazing presentation as always 💯
Thanks Brian. Zoyi 703s can export images to sd cards. Has dual channel and is a handy tool for fields. For more information search the model number provided, there are tons of reviews out there. Cheers Max.
Hi Max, thanks for another interesting video. You seem to have more tools than the average dealership! I have a similar but different problem on my 2006 CLK350. The AC works, as does the heater, but it doesn't seem to have any temperature regulation. It is either full cold or fully heat. The only way that I can regulate it is with the fan speed. Any ideas?
Will the solenoid go bad entirely or may it retain some residual function (but not work fully)? My AC in my CLK works, but it is not working wonders in terms of generating cold air. There appears to be sufficient refrigerant in the the system and the cooling performance might be normal; I'm just not sure. Flaps are also OK, i.e., I don't have the infamous clicking noises from the dashboard.
Everything is possible. Depending on what position the solenoid gets stuck. Best would be to diagnose using a good scanner to check the evaporator and all the ducts temperature.
@@BenzAddiction Thanks a lot, for the reply! I have two very good scanners (Benz-specific ones) and they don't show any fault codes. The air temperature responds to dial operation, i.e., when I reduce the temperature on the controls, the air gets colder. The cooling performance is just not "blowing me away." :) I've heard that one shouldn't use Japanese cars as a benchmark as they have wild AC cooling performance. On another European car I owned, the cooling performance was similarly "weak" compared to Japanese cars. When you say "check ... all the ducts temperature" are you suggesting a real thermometer to measure the ducts, or are you talking about read out values shown by a scanner (live data)?.
Hello Benz Addiction WoW - you have some amazing easy resets on your channel..! Please if you cud direct me. My 2011 A-Class has a problem with the park light ( called main beam by some ) that stays on for no reason. All light switches are off in the car. Yet beam is permanently on. We removed the bulb to stop the LIGHT from draining the battery. I see on line many have had this problem. But no full answer other than it can be the SAM Moduel Can you advise. Thx - Rosemary
@LimitlessLovve Hi, not very familiar with A class, but yes, most of these headlights are controlled by the front SAM module, I suggest you to diagnose using a proper scanner before attempting to replace anything.
@@LimitlessLovve Not necessarily, it is recommended for the Mercedes-Benz owners to have a scanner. A Mercedes dealer usually charges more for such complicated fault, a good Indy mechanic if you know one might be way cheaper.

@@RobInAus Hi mate, it probably is the AC flap actuator not working
I have a 2006 Sl500. So, it probably is clutchless? Thanks!
Definitely,. You are welcome.

Yes, the EU A/C might not compete with some Japanese ones. But it should be adequate. Yes check the temperature on the scanner.
@@BenzAddiction Thanks!
@coolcat23 You are welcome.

Thankyou Benz Addiction. Does that mean it need to go into Mercedes Benz workshop ..?
