Ask your mechanic if your car has a monovalve control for the climate unit. These go bad in Mercedes as soon as 60k miles. It's basically a thin rubber disk that is moved up and down. Once these rip, the symptom becomes occasional a/c or occassional heat in a hit or miss fashion. The repair is under $500 - or should be.
