300SDL air conditioning leak

[Marvin Smith]

My air conditioniong does not work due to a coolant leak. My mechanic replaced the refrigerant in the car and it worked well for about a month - then it quit working. I asked the mechanic if he had used dye to find the leak and he assured me that he had. Hot weather is here again and I still do not have a functional system - what do I do? The car is supposed to go to the shop this week.
