C180 ac hi, my father own a mercedes c180 w203, the problem is the air condition will blow warm air when the car is not moving/ moving slowly, but it works perfectly/blow cool air when the car is moving fast. So, Im just wonder what is the problem? i went to a several mercedes workshop, some of them said it is a fan problem and others said compressor? how do i fix this.? can you please help me?

Hi there

BAS is the Brake Assist System and if there is a malfunction it would only come into play in an Emergency stop while applying full pressure. BAS applies full braking force because people tend to lighten up their pressure on the pedal in these situations. I would suggest that the best thing to do is go to a Workshop or Service Center and have it checked out. Please remember to put a good rating on my profile.

Kind regards

HI, giving the compressor 12v directly is not the way to go as you are bypassing the entire fail safe cercuit. it seem to me that your ac gas is low(can be checked via ac pressure gauges) wich means you have a system leak sumwhere. as soon as your hi/low pressure switch(depending on system) detect inferior pressure to the spesified pressure ,the ac compressor voltage is cut in order to protect the pump from seizure.

Or perhaps your evaporator(small radiator like unit behind dash) can get freezed up caused by either too mutch system gas(check pressure) or poor opperation of the expantion valve. the evaporator then has a sensor(themometer) wich measures evap. temp and if the value drops below spec (usially round about7degrees) the ac compressor will be cut once again(fail safe)

Maybe your ac compressor overheats due to inferior system oil/oil capasity, also note that only some systems incorperate the function of measuring ac pump temp. then again temp to high= fail safe=no12v to ac pump.

Good luck.

freeze plugs no good

SOURCE: AC does not cool while idling,(blows warm air)

1'st check to see if the a/c belt need's to be tightened,if tight have your ac pressure checked.hope this helps,

SOURCE: AC blowing warm air

When they refilled the refrigerant did they put die in it to check for leaks, it sounds like there may be a leak.
