    Hi, 2001 E320 W210. (European)
    See picture of Control Panel.

    There does not seem to be anything about my particular problem. Climate Control Panel a (2) (Small).JPG
    The Air condition quit. No Power.
    For a long time the Blower has been faulty. I had planned to replace it or at least the brushes.
    The speeds all worked fine.
    The blower would just stop for a while and then start back. Sometimes a few seconds and sometimes an hour.
    The Compressor would continue to run and I would select “EC” until the blower started up.
    The little red light on the “EC” button would come on when “EC” was selected.
    Last week I parked the car and the A/C was working just fine.
    When I started the car some hours later, the A/C was showing no sign of life.
    The compressor would not come on and the light on the “EC” switch would not come on.
    I have checked all the fuses that I could find that said Blower motor A/C.
    I have not been able to determine if there is a “master” fuse for the A/C.
    Also, this car has a single engine cooling electric fan. No Aux fan.
    That fan seems to run at full speed as soon as you start the engine.
    Before I take it to the Dealer, I was hoping to give it another look.
    There seems to be no power to the A/C.
    I know I will have to start from the beginning with the fuses and go forward.
    I am hoping someone might give me an idea that will make the journey shorter.
    I am hoping that if I can restore power, it will come back to life.
    I do not have access to a good code scanner and I think I would need a “Star” scanner to see all those A/C sensor readings because it is not the “Digital” (USA Push button) version that can assess the sensor values.
    I also have a slow leak on the evaporator. It takes about three months to leak enough to require a top-up.
    I am looking at a product called CryoSeal that has been mentioned here.
    I am reluctant to add anything to the system because I have read too many warnings about additives.
    I need more user experience reports.
    Thanks
    Joe

    Regardless of any other faults with your A/C if you have a gas leak you should get that fixed before you do anything else. Continuing to allow A/C gasses to escape to atmosphere with no attempt to fix the fault is plain irresponsible. I know the evaporator is a dash out job and that you may have a very high ambient temperature out there,but these gasses are not good for the planet. In the UK you would not get it topped up in a service centre if the machine picked up the leak. How sure are you that it is the evaporator leaking? and not the condenser, evaporator failure is not that common.

    Thanks.
    Gas coming from the air vents.
    As I mentioned in my post, I am going to fix the evaporator. It might be a seal.

    O-ring failure is usually a result of the seals drying out due to lack of use, which I think will not be the case with your car due to your location. The sealants are not recommended but faced with the choice of pulling the dash out or trying a can of sealant I know which way I would be going. "PASS ME THE CAN PLEASE"
