Хорошо сделано, ещё лучше было бы разобрать старый компрессор

[@jacobramos8868]

El a puesto un nuevo compresor... Sale en el video

I just bought a wagon one of these! I noticed when I start it, there is a whining noise. Seem like it’s comming from AC. Hoping I don’t need to replace stuff

Welcome Can I use R134 gas instead of R12?

My '91 300E is making this loud screeching noise when I start it in the morning. It goes away when I rev it. Could it be the same fan clutch?

[@charlesmathews36]

My AC fan is very loud and squeaky. How do I change that?

[@confortvoyage8653]

Hi dear plz can you give me reference of compressor of w124 in denso mark ?

[@biopump2000]

So, how do you diagnose that your compressor is not engaging? And you also said that your wires were not getting power here 2:35 - so, I'm a little confused. Did you have wiring problem as well?

[@IgnatBK]

I manually ran 12v to the compressor while the car was running to see if the clutch was activating and it was seized that’s how I determined a bad compressor, the no signal to the compressor was due to the switches which I replaced, also check that your car is holding Freon or vacuum before you diagnose further could just be low on Freon.

Na zatarty kompresor , układ montujesz nowy kompresor ? . Nie masz zielonego pojęcia o klimatyzacji a myślałem ze tylko w Polsce jest tak . Możesz nazwać się wymieniaczem . Widziałeś jak twoja maszyna do serwisowania klimatyzacji wygląda, dosłownie jak by ją ktoś z śmietnika wyciągnął. Zaczynam tobie współczuć , jeszcze wrzucać to na yt brawo ty

[@HybOj]

question is, if trying to unstuck the compressor would be even possible... and economical. Im not so sure the old one had any life in it

I have oil pissing out of the small radiator just in front of the left front wheel. The AC has not worked in over 15 years of ownership. Is this dangerous? Thank you.

[@IgnatBK]

Yea replace the radiator

[@samanbehnam7359]

On my 124 (1994) I charged the system and worked fine but overnight all the Freon was gone. I shined a black light next to compressor and no leak Under the car on the passenger side transmission tunnel I see a lot of Freon near the condensation tube Does this mean the evaporator inside the cabin under the dash is leaking or the expansion valve has failed ? I don't smell Freon inside the car.

[@IgnatBK]

Could be run a vacuum test if you can and try to find the leak

[@samanbehnam7359]

@@IgnatBK if the evaporator is leaking it should show when the AC system is connected to the charger correct ? Last time it was connected to the AC charger the technician said he does not see any leaks.

[@IgnatBK]

@@samanbehnam7359 sometimes it only leaks when you pressurize the system I’ve had that happen before

[@samanbehnam7359]

@@IgnatBK I'm hoping it's the expansion valve otherwise the evaporator replacement is difficult.

[@Rimvydas_Pocius]

@@samanbehnam7359 For me its evaporator radiator is leaking. :( I will try to fix this winter.

Łatwiej zrobić to na sterowniku pin 5 i 7. Nowy komoresor po zatartym bez płukania układu? 😂Powodzenia. Gwarancja do bramy potem się nie znamy. 🤣🤣Test szczelności wakum? Gdzie azot lub mieszanina? 😂😂 Dramat.
