2003 Mercedes-Benz ML320 Problems

Power Window Main Switch May Fail

The power window switch may fail and the windows will not raise. The main switch at the front center console is commonly at fault. A failed switch will require replacement.

AC System Leaks/Bad Temperature Sensors May Cause Poor Cooling

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.

"No Start" Due to Drive Authorization's Failure to Recongnize Keys

A no start condition may develop due to an anti-theft system fault. If the drive authorization module fails to recognize the keys, the engine will not start. In many cases, a new module and keys will be needed to correct this problem.
