Mercedes-Benz ML500 Problem
6 Reports
Model Years Affected: 2002, 2003, 2004, 2005
Verified
AC system leaks and/or a faulty evaporator temperature sensor can cause poor AC cooling. The failed sensor can prevent the AC compressor from coming on. Leaks cause a low refrigerant level, which reduces the ability to cool.

the AC blows out warm air..sometimes works though...when it 1st started happening, it seemed like if I rolled the window down the AC would start working..
