The fans run?

The fan runs for? not at maximum speed

The fan runs for? not at maximum speed

Hello, the fan could be normal, I do not know in detail the mercedes, but it could be that the need for concurrence of the request for the climate and for the engine for which is active the maximum speed.
you can do some test, to a minimum when you attack the air conditioning to low temperature feel the compressor "attack"?
Starts on and off at short intervals, or remains for an extended period of time?
in the cockpit, you should see to ear a hissing sound from the bridge, you feel it at regular intervals or continuous? If at regular intervals, " ok, if you whistle long low of gas.
You say that the gas ? ok but have you tried to do a test of the pressures? it could be that you are missing a 30ina of grams for which the minimum does not reach the working pressure.

I hope this information was useful.

Greetings

I hope

The compressor attaches to continuous to with regard to the gas ? just been recharged.. But if the car and stop no air comes out cold only if he walks

freddyecu
Another thing of the problem the fan was accelerating now, however, no

if from a stop and accelerate? hold on a few sec on the 2000/2500 rpm and see if it decreases the temperature, doesn't it ? said that as soon as charged it is in place, sometimes get the wrong quantity? gas, gi? happened several times, lathes, 50g of gas in ir? and everything works to perfection.
for the fan you should check in traffic when the engine gets to temperature, as I said, perhaps do not reach the temperature for which the second speed.
P.S. don't look at the temp in the cabinet ? fake, when you get straight, and the hand actually? you are at 70? c.ac T water

You if accelerate works the amount? gas messi 850gr

You if accelerate works the amount? gas messi 850gr

you have the frame?, any model I have read leads 950g, probably something is missing, and the minimum can not lead to the exercise of the pressures, you should return from those who have reloaded and fargliele control to a minimum.

I'll try 950g, and still fact-checking the pressures.

sorry if I'm intruding but I comincierei to check the pressures ,which pressures you to both the low and high

I had the same problem on my Volvo, have fixed by replacing the radiator fan under warranty.

Pierchip
The symptoms were exactly those described.

tecnoracing
if you connect the pressure gauges and check the pressures you notice if the fan cool enough the condenser cio? if the high-pressure arrava 20 and normal that you have a problem cooling the high-pressure should not exceed 14 max 15 bar if off the fans you get to 20 and the compressor goes into stall correct me if I'm wrong

Those cars are very sensitive to the amount of gas in the air conditioner, and a difference, even minimal, can? give it to malfunction.

In addition, there are versions that mount 750g and versions that stick in 850, you can verify the label located on the box the cabin air filter located on the battery compartment. If you put 850 in the car, that mounts to 750 up too much pressure and it goes into the block, the climate.

Also you must tell me if you have the manual climate control, with knobs or the digital one with lcd display. In the second case, it could be another problem then I solve it like above, I will illustrate how to solve.

have you checked the compressor ? see with pressure gauges pressure if the compressor at the minimum speed to pump the gas usually are their

How to describe the problem needs to increase the rpm of the compressor to make it work then ? a lack of gas.
It had been the opposite of that? that worked to a minimum, and then acceleration to accommodate travellers, it would be an excessively large quantity.

freddyecu
Tried 950 gr and ? worse then ? been loaded to 750 gr all ok, the problem was that he was 100 gr in ir? ...

also check the sensors-pressure gas to me on an audi to become crazy, changed the sensor, everything is ok

franco-electr
according to me, should first accelerate from a standstill to see if it starts to cool down if it is not ,it is definitely a cooling problem or an excessive amount of gas

et600
frankly wrote that he solved and the problem was the excessive amount, it is useless to continue to churn out the diagnosis when she posted the solution, no?
