    short cycling is usually caused by low level of refrigerant. When the compressor kicks on, it takes the pressure down on the return line and the pressure switch opens, cutting off the power to the clutch. Charge the system one can and it should be fine for a while.

The most common cause for this is low freon.

Need manual for dac 8075ee air conditioner

I split this into 3 sections since I'm verbose.
1. Reasons to use it
2. Theory behind a/c and how it works
3. Steps you need to take

1. This is an easy method of reducing your FE losses due to A/C while retaining some of its benefits. I have to use my A/C when I'm dressed up in a shirt and tie as well as when my wife and/or baby are in the car, and I use this to keep everyone, including my wallet, happy.

2. Basic air conditioner theory: Your air conditining is operated by an engine driven compressor, then two "radiators"; a high pressure, hot one that is warmer than the outside air, and a low pressure, cold one that is cooler than outside air. Thermodynamically speaking, when the compressor does work on vaporized refrigerant to compress it into a liquid, its temperature increases. This is an adiabatic process. The high pressure refrigerant travels from the compressor to the condenser, which is in front of your car's engine-cooling radiator. Since it's now very hot, it loses energy to the outside air flowing through it. After losing energy, it travels to the inside of the car, passes through an expansion valve that allows a small amount of refrigerant to pass through. The refrigerant then enters the evaporator core, an area of low pressure. The liquid refrigerant evaporates, absorbing energy from the air inside your car, and then returns to the compressor.
Your compressor does not run all the time your car is on; it also doesn't run all the time your a/c is turned on. Most cars' expansion valves are thermostatic; they work to maintain a constant temperature within the evaporator core. If the expansion valve only allows a small amount of refrigerant through, the pressure in the high side of the system doesn't drop. A sensor detects this and disengages the clutch on your a/c compressor.
Therefore, if you do what you can to keep the evaporator core cool, you can decrease the percent of time your compressor is running.

3. What to do: Two things will allow you to keep your evaporator core cool and your compressor clutched off. First, always use the recirculate function on your climate control. Already cool, dry air flowing through the evaporator won't warm it up as much as warming fresh air from outside.
If your car doesn't have a recirculate switch, chances are that it has a "normal a/c" and a "max a/c". Use the MAX! This seems counter-intuitive, but since the recirculating a/c works better, it's labeled as such, and it's also more efficient.
Second, once you get your car to a cool enough temperature, adjust the blower fan to the lowest speed setting. You still get cold air blowing on you, but the smaller volume of air that flows through the evaporator, the cooler it will stay.
Using these two steps, you can have your a/c and afford to eat for dinner too

Brake lights on mb ml350 don't work even after installing new bulbs

The brake lamps on your Mercedes are computer-controlled. I would recommend scanning your computer network for possible fault codes.

On 12 year old AC fan works, but there is a periodic muted buzz but compressor doesn't engage.

The hum is generally attributed to the compressor trying to start- being intermittent suggests it is failing and going into a delay via an internal safety switch. Assuming this and the fan you speak of is the condenser fan there are 2 good diagnoses- either the run capacitor is bad or the compressor is locked up. I would change the capacitor and install a hard-start capacitor, if the problem persists it would most likely require a new compressor.

The heater works just fine, but the air conditioner doesn't

The heater works on an electric coil...
The A/C must run the compressor...
If A/C does not work then the compressor is not working...

Our Danby model dpac 11006 was working fine yesterday but came to put it on today just to find out the ac doesn't work the fan still blows just no cool air . we do hear something in and out like a...

The intermittent sound you're hearing is probably the compressor trying to start. This could be caused by a bad circuit or the compressor motor is seized If the latter is the case, it's time to start shopping for a new AC. As the cost to repair would be almost as much as a new unit depending on the age of your unit. However, compressors usually have a 5 year limited warranty. So check you Owners Manual for details. It may still be in warranty.

Hope this helped you and thanks for choosing FixYa.

Look at the wires that go to the compressor and make sure they are not burned off. Inspect the capacitor tops for swelling and loose or burnt wiring. Also check the connections coming from the controls. May have a wiring problem or even a bad compressor. How old is the unit?
