MERCEDES GL 450 THE AIRCONDITIONING STOPS WORKING RANDOMLY

2008 Mercedes Benz GL450 • 49,000 miles

AC just goes from blowing cold to normal air temp intermittently usually once a day for 20-30 minutes, then it resumes normal function

I have the same issue with my AC ( GL450 2009), I took it to Mercedes dealership and they too are guessing what might be the problem. They wanted to change teh Climate Control unit for $1700 and that is not guarnteed that will work. Did you find out what was the cause?
