Air Con compressor won't engage - 99 ML 320
Hi, I am new to this forum, and this is my first post. So Hi to everyone out there.
Second, I have a 99 ML 320 - and I am having a problem with the air conditioning.
The Air compressor does not engage when it is turned on, regardless of outside temp. You can turn it freely by hand, so it's not siezed.
Does anyone know what that might be?

Most likely low on gas and when the pressure is low there is a cut out pressure switch that prevents the compressor from engaging. Have the system leak checked, repaired and refilled.
