A mechanic friend (not mb mech), checked the freon level and determined that the system was not leaking freon.
But could not determine why the compressor is not kicking in
without hooking up to diagnostic equip, which he doesn't have.

with the system holding it's freon, I don't believe I would have to go to the extreme evaporator replacement route.
So I was hoping a good mech who knows MB can work on the AC without the dealer/srvc prices.

thanks.
