W124 300CE aircon absenteeism

[LNM]

All

Just solved the buzzing thread thanks to Justin, Ade + Spike. We need an online pint-delivery-system implementing here.

Aircon does nothing but blow imperceptibly chilled air at me even when _both_ wheels are on 18C. Only unix servers can stand this kind of chilling but the interior ceratinly does not go anywhere near that temp even after a 30 minute drive.

I'm assuming that the aircon system needs "recharging" (whatever that is; dumps a load of CFC back into it I presume ?).

I'm also assuming that because there's no option to turn the aircon off, its always on (du-uuh) as in climate control rather than aircon; hence buzzing from blower motor that monitors interior air temp.

If I elect not to fix the aircon, will the aircon pump do less work + maybe gain a few extra mpg?

Could categorically answer my own question by removing the pump altogether and fitting a different poly belt I suppose.....

Your help, is as always, very much appreciated. This is the best site on the web.

are you sure that you have got air con cause usually there is an on/off button with ec on it, ec stands for economy so when the lamps on the air cons off?

Pretty sure; just assuming that it has because how else could it get to 18C and why would it try to minitor the interior temperature?

two wheels, one either side, two knobs, one with fan speed the other with direction of airflow. Unless I'm losing it completely, there's no other buttons anywhere.

I can check for sure by confirming the existence of a compressor in t'engine compartment.

Sounds like you dont have aircon, just the mercedes standard heating / ventilation system - this still monitors and controls the temperature via the pipe etc but will not chill the air in any way. almost like climate control that only allows the car to be warmer than the ambiant temperature. If all you have are two dials marked with temp and two others (fan speed and air direction) then you dont have air con, which is not really a bad thing as my experiance with it shows it causes more problems that it is worth.

Thanks for advice. Again, I need to read the manual. Good thing is though, as you say, its all simpler will use less fuel.

(Stock argument from all of us without aircon!!!)
