My 1999 C230 was driven through a lot of water recently. The MAF was replaced as well as the the cabin filter. Apparently, water went through the air ducts and was expelled into the interior of the car. The fan would not operate. The dealer changed the MAF, changed the oil, cabin filter, etc. but didn't check the AC. Took the car back and they recharged it. Went to 41 degrees but a week later no AC. I'm taking it back in on Monday.

I need some help because the insurance company doesn't want to pay to fix the AC. It worked perfectly until this water incident. Did the water allow pressure to build up in the system and cause a refrigerant leak? Any theories? Thanks.
