2001 Dodge Intrepid BCM or Ignition switch?

My 2001 Intrepid recently started to shut off the AC, PW, PL at will. After bringing it to my mechanic the codes revealed BCM problems. I just replaced the module and still have the problems. I have been told that the ignition switch if worn can cause similiar problems. The car was stolen in 2005 and the column was slide hammered during the theft. It was repaired. Have you ever hear of this. Perhaps too many keys on the key ring.
