Water got inside truck , now air condition won't turn on

Hello, how much water got inside? If you are speaking of a nominal amount of water controlled by cleaning and not freely sprayed, then nothing should have caused your air conditioning to fail. The only thing I can imagine is that something could have caused one of the fuses to blow, so check there first. Beyond that, test your failure by checking the related systems and testing with proper equipment.

Actually there is no repair protocol for water intrusion. Good luck!
