2002 Dodge Grand Caravan electrical system problems

I experienced ramdom failure of the headlights on my dodge caravan. I brought this to the attention of my dealer and they said they "could not duplicate concern". I was told the cause was probably the "front control module" but they would not replace it because they were not positive it was the cause, and because of the cost of the part. After this occured the second time I took it to my own mechanic and he replaced the module at a cost of $307.05. The replacement occured 9/15/2004.

Tl*the contact owns a 2002 dodge grand caravan. When the air conditioner is activated, the passenger side floor becomes damp. Also, the lcd screen on the radio no longer operates. The vehicle has not been inspected by a dealer. The contact was unable to determine the cause of failure. The current and failure mileages were 96,000.
