W204 air con

[legend]

Hi guys.

Couple of months ago, when I sent my W204 to my regular workshop for a routine servicing, I mentioned to the boss that my aircon is not very cold compared to my previous ride. More specifically, the air coming out from the vents is not strong and it is definitely not very cold as well, especially when the car is stationary. Having said that, the boss recommended me to do an aircon flushing. Thump chest and said that sure can see the difference.

 

Anyway, to cut a long story short, I did aircon flushing (no use)followed by replacing the compressor (improved the air flow but still not cold) then the cooling coil (still not cold and worse, air con breaks down after 1 week)and lastly replaced the condenser. (Aircon temperature still not to my expectation). Now I was recommended to change my aircon blower as well!?

I would like to check with the bros here, how many bars did you use on for your air con and the temperature you used when you are driving in the afternoon time? For me is 3 to 4 bars and 17 degrees in the afternoon. Morning would be 1 to 2 bars and 18/19 degrees.

Hi, 

Need to separate  air flow rate & temperature , the air coming out can be strong, but not cold .. or vice versa .. 

if it's air flow issues, then it has nothing to do with compressor ... it's related  to aircond filter (blocked), or blower/vent opening.. item that can affect 'air path".  .. if it's temperature issues, then it has to do with compressor, cooling coil , thermistor related item 

Since u have changed compressor but air still not cold enough, not sure u have explore .. there is a themistor (sensor than measure cabin room temperature) + small fan (that help to suck air from cabin to thermistor) , that locate inside the front indoor light cluster (near to reverse mirror area) .. if the thermistor issues, it'll send to wrong temperature info to computer & regulate wrongly

Hi bro Catfish

Could not be the thermostat or aircon filter as I have also replaced them earlier. Is it true that conti aircon is inferior compared to japs ride?

my experience with driving 2 w204s, the air con is very good. It takes less time to cool the whole cabin down even though park under hot sun.

w204 aircon is good. maybe air con gas leaked?
