Cascading electrical systems failure on 2003 Ford Crown Victoria

My '03 CV Sport is sending me some bad vibes. First, the blower motor failed, then the power locks, inside trunk release failed, including the outside number pad and remote. I paid for a diagnostic, and they tell me the door control module is bad, but have also been told that the body control module may be suspect. The diagnosticians told me that I need to replace the blower motor speed controller, however the entire HVAC control assembly was replaced last year; only blew threw the defrost. I disconnected the wiring harness from the blower motor and hooked up an auxiliary switch and the motor runs fine, including heat & A/C. What would your recommend ?
