I have a 1998 Plymouth Grand Voyageur with 195,000 km on it. The signal lights stopped working so Chrysler service replaced the flasher, which fixed the problem. After that the 2 interior lights above the console stopped working. A) Could the signal light and interior light problems be related (i.E. Resulting from the flasher replacement or caused by a BCM malfunciton)? They say the interior light problem is a malfunction in the Body Control Module and it costs $1,300 (CAD$) to replace. B) Does this sound reasonable and if so, can BCMs be repaired? C) I haven't replaced the BCM as yet. Since finding this out the delay control on the windshield wiper has ceased to work. The standard 2 wiper speeds still work, however they occassionally decide to continue wiping after being turned off. Does this sound related to the BCM as well or what could it be? D) Is it possible to buy a BCM and install it. How difficult is this and how could I find instructions?
