Various Electrical Issues Due to Internal Body Control Module Failure on Chrysler New Yorker

Instrument cluster gauges, panel lamps, and electric door locks may not operate, and the courtesy lamps may remain on. These faults are commonly caused by "logic lock-up" of the body control module (BCM). If this is the case the BCM should be replaced with a revised version.

My Problem Started in when a Short was found in Vanity Mirrors & Dimmer Turn Signal Switch. Replaced Battery & Dimmerswitch. ABS Trouble Light came on. Now Transmission would not shift out of second gear. But now have several Electrical Issues. Checked all fuses & Relays. Alternator & Battery. All Good. No Poewer to Lights, Power Door Locks & Windows. Radio A/C Controls Radiator Cooling Fans. It seems to be ok after removing Battery Cables to reset BCM. But a Surge or Failure is exploding Bulbs for #3 Brake Light. These Bulbs Blow & all kinds of Problems Start. Car Has New Battery, Alternator & Belt, Dimmer & Head Light switch & Relay for Transmission. I am Checking all Connection for Ground & Contact not corroded or Damage. Has 157000 miles now & has been a Reoccuring Problem. Security System seems to be the weak link. Reset it by cycling key 3 times in left & or Right door. Seems to reset system. Do this everytime Loss of Power or any repair to Vehicle.
