No power to A/C controls...
 

My daughter has an 2002 325i and she is not getting any power to her controls. She said that she ran through some fairly high flood waters a while ago and the a/c stopped working. She took it to a mechanic and they checked all fuses and they said they were good. They also checked the blower motor and the compressor and they checked out good as well.... Any ideas on what it might be?
