A/c problem
Hello. I have a situation in the car.
I checked with the Mercedes dealership and found a problem.
cause: air conditioning does not work. the representative told me so:
the needle compressor is electric and is powered by a large hybrid battery. but that hybrid battery has 3 valves, and one "does not open" and does not send the command to the air conditioning compressor (the compressor works has been checked). the problem is that I did not identify the defective part / valve as part / part code. those there didn't have an electrician licensed to work on hybrid cars and they didn't help me.
how to proceed to identify the piece any advice is welcome.

Alex,
Is MB hybrid a 126 volts ?
Also this one : http://assets.mbusa.com/vcm/CAC_RAPM...HybridFAQs.pdf
I suggest if you are dealing with voltage higher than 48V and more so above 100V, do be very careful and STOP........if you are not well versed with at least a 220/380 Volt home use.
I googled Romania is a 50hz 230/400V , same as my country.
Stay safe........

Thanks a lot for the reply. I'm careful. and honestly I'm not going to start solving the problem myself. we ask if you have ever heard of such a problem and if that "valve" changes easily and can be found to buy for replacement. because I know it's no joke with these batteries and it's pretty dangerous to walk there. thanks for the advice and opinion.

The PDF file I linked shows how the HVAC works, as it is also the battery cooling system.
Paper page 10
I think what you meant by :
the needle compressor is electric and is powered by a large hybrid battery. but that hybrid battery has 3 valves, and one "does not open" and does not send the command to the air conditioning compressor (the compressor works has been checked).
Those 3 valves could be Y19/1 High-voltage battery cooling system shutoff valve and Y67 Rear air conditioning refrigerant shutoff valve and maybe inside the item 2 - Fluid reservoir there is a solenoid/valve too.

as an add-on ... the MB people who checked the problem told me that the battery is in the parameters. they also checked the cells and they are ok. and only the "valve" that starts a / c would be the problem.

Thanks for the info because I'm putting everything in order now and you'll know what to ask for. And yes, in Romania there is a problem with these electricians for hybrid cars, even electric ones, because they are not very. but I hope to find. I will try to get in touch with those from MB on Monday, in the hope of a quick appointment, I will let you know and I will keep you informed of the problem.
