I also had the same problem. a/c system on mercedez s class is very sensitive,  you must discharge the old freon and use new freon as specify on the manual, and precise pressure : 14 bars. you may find the specification under the hood. if the pressure go under 13 bars, the compressor will automatically shut off, and the red light on the EC button will be on.

this is the probleme with luxury cars ...the venting systheme works with vacum and some thime smal electris motor ...if one is broken or a hose craked ...this kind of stuff appens not much to do but to take the under dash apart and look for the problem, it could also just need a little lubrification on all the moving parts !

SOURCE: can't turn off EC on temperature control on a 1997

Press the O button to shut it off or any other button. Usually when the E/C sticks on its an A/C charge or sensor issue so check that also.

The pulley on the air condition has to turn it has a belt on it. The Compressor engages to pre cool the evaporator. Most likely you have a blend door pod leak or leak in the hose or the sampler valve is bad. I would replace the sampling valve behind the glove box/air bag. As that reads the cabin temp and if it thinks the car is cold the heat will stay on because everything is automatic. All vents will blow cold when it thinks its hot and in addition to floor and corner dash center vents will blow cold when it works. If the direction of air is correct then the A/C system may have a leak or need a charge of freon.

There's some rust on my transmission dip stick, what type of sign could this be? And I had the truck running for over 30 minutes idling, should the transmission fluid level be over the cold level and up...

If you are in Park, and running ... there is little activity in the transmission. I would say you are probably "cold" at this point. On the other hand, if you drive around the block, there is a lot of activity in the transmission and you are probably "hot". I wouldn't add any fluid based on your observation today. I would check it again tomorrow and see what the level is.

Here is a tip: Never add all you think you should at one time. It is a bear to get the fluid out and over filling is worse than being a little low. If you over fill, the tranny will whip the oil up into a frothy mixture, the oil will expand and do little lubricating. Frequently, when this happens, the oil runs out the fill tube onto the hot manifold and there is a fire as a result.

As far as the rust goes ... surface rust on the dip stick isn't much of a concern. It would tell me there is no oil coating on the bare metal. When moisture gets on metal - rust. So, how does the moisture get in to do the rusting? When your transmission is hot, the air inside gets hot and it expands. The extra air escapes out the fill tube and in come cases a breather. When you park, the machinery cools down, the air 'shrinks'. When this happens, 'fresh air' is drawn into the fill tube. Sometimes, the cooler air is heavily laden with moisture ... the moisture condenses onto the metal parts (and onto the oil) causing surface rusting. The water that gathers on the surface of the oil will eventually sink. Next time you go out, the machinery gets hot ... the water evaporates and mostly escapes out the fill tube with the hot air. When you turn the machinery off, ... this process starts all over again.

I hope I have addressed your concerns today, and I hope this makes sense to you. Thanks for your interest in and thanks for your visit.

My 1994 Mercedes c220's fuel gauge stopped working

Fuel level sensor is in the gas tank, may be faulty or just dirty, make sure to fill the tank entirely full with premium unleaded, ad a high quality fuel system cleaner / de-gunker, this may clean the sensor enough to feed back to the gauge. It could also be the fuel gauge itself, but that is less likely. Mercedes will be happier with at least 1/4 tank of fuel at all times, and don't skimp on low octane gas!
As for the check engine light, you may have a bad gas cap... believe it or not a gas cap that doesn't seal properly will throw the check engine light. If you get the codes read (for free) at an Autozone or similar parts store it will likely read "evap system" as the problem, which will likely end up being the gas cap.
Take your car to a service center that does a true "flush and fill" of your a/c system. Those little canisters will just waste your money, and they never truly clean and re-lubricate the system like a flush and fill will do.

Im going to live it parked for 3 months

Hi, 3 months is not that long for a car to sit. But yes, turn the air suspension switch located in the trunk to "off", disconnect the + positive from the battery post under the hood, and last fill the gas tank (full) to prevent inner gas-tank corrosion. When you return, connect the + positive to the battery, start the car, then turn the air suspension switch to "on". Don't be surprised if the air bags in the suspension lose some air while gone, the bags are known to leak.
