Q&A

 Master

I presume the fan blower works. The air conditioning compressor has a low pressure switch to protect it from working when the air conditioning pressure drops bellow a certain point. If the system looses pressure the system has a leak and it must be located and repaired prior to just replacing the R134 refrigerant. Air conditioning work is expensive. A shop can't really estimate the cost of repair until they know the source of the leak. The problem can be mechanical or electrical. To diagnose the system repair shop will probably start with a one hour estimate for labor.

Call you local MB sevice dept and refer to this Recall Information. Inform them that your year model is having the same issues. You may be able to have the repairs completed at no cost. If your MB dealer's service dept Is not receptive, contact MB headquarters. I'm having the same problem with my MB and will call MB this week.
