SOURCE: My air conditioner won't blow cold air. It just blows air.

Hello I'm a M.B. tech. 1st you need to know why the freon is low. Hopefully it just needs to be serviced. There is a component located in the lf of the engine compartment called a receiver drier. It soaks up the moisture in the freon so the gases can work the way they are supposed to. On this unit there should be 2 switches(I believe they were combined into one switch in 98. 1 switch is a temp switch that operates your electric fans, the other is a compressor cutoff switch. Assuming the compressor is not coming on-take a fused wire and bridge the 2 contacts- If the compressor does not come on at all there is another problem(it is not low on freon. On the condenser there is a high side port(it is the bigger of the 2)By the brake master Cyl.(lf of the engine compartment thereshould be a smaller low side valve in line with the fuel cooler hose. Usually you can hook up a machine to the low port and **** freon in through that port. Assuming you do not have a refrigerant machine. It is very self explanatory on the bottle of r 134a refrigerant which can be purchased at your local auto supply store. I would start with 1 lbs. and add dye with the freon in case there is a big leak. If the system is overcharged it will not cool properly. I believe the system capacity is approx. 2 lbs. Add a few ounces after the first pound until a/c system is cooling properly and the electric fans are also coming on when the system gets to high. If you get a can with a good Gage set on it you should see the high side between 150 and 2000 psi(fan coming on at max. press.) also the low side should read about 35. It is about the temp of the evaporator which is i=located in the dash and the blower blows through this component out through the vents. Hopefully I have been helpful.

SOURCE: need ac reset for a 2003 e320 Mercedes

You could need a recharge of freon or your A/C pump is bad. You can go to your local garage and have them recharge with an aftermaket freon kit or the dealer and have them put it on an a/c machine and really diagnose the problem

SOURCE: Air conditioner blows hot on one side 1999 mercedes e320.

On the 1999 E class this is generally a problem when teh freon level is a little low. Sounds strange to blow cold on one side and not the other but recharging the system is the typical repair. You will also have to find the leak to keep this from happening in the future. There is an updated receiver drier for this vehicle depending on the vin number. The earlier version has a large(about the size of a nickle) sight glass in the top which cracks and allows freon to leak. The new version the sight glass is much smaller, about the sixe of a dime. Recharging the system should be the first step.

SOURCE: 2001 Mercedes S500. Air conditioner won't blow cold even though

I think that this might help you. The a/c compressor is a continuos running type there is no clutch. It has a wobble plate internally wich changes the piston stroke. Screw the genises machine-it is probably only reading a partial on the climate control module. see if you can find the self diagnoses diagram either from the factory or if you have all data. you can pull the codes right from the unit itself and they will be accurate. If you can,t pull codes see if you can get an actual value of the sensors in the a/c unit. You should be able to pull that up as well if not try the genisis. Look very closely at you evaporater sensers(left and right) you will probably see a -40 degrees-that is the sensor default input reading when the sensor goes open. That sensor is used to moniter the wobble plate position of the compressor.

SOURCE: air conditioner isn't blowing cold air

Could be a number of things...electrical connections causing the compressor not to run. Turn on AC and turn your thermostat all the way to visually check to see if compressor is engaged and not just free wheeling. Most likely you lost your refridgerant due to leak in the system...would need to find leak and repair then have your system re-charged with refridgerant. Best case scenario...your system just needs a charge of refridgerant due to not having enough.

Air conditioner blows hot air C180 2006

Taking a week seems a long time, makes you wonder if they dropped a clanger during the job.
Sounds as though they have disturbed a pipe in the A/C system, possibly lost your gas and may need recharging.
TAKE IT BACK to the garage.
Good luck

You may need a mechanic for this.
In most cases the radiator fan is not pulling enough air thru the condenser when you are not moving. Either the fan is not running or there is a blockage.
