Turn Signal Flasher Unit Problems of Dodge Ram 2500

Truck was purchased used with 16000 miles. At approx. 20000 miles, an anomaly with the turn signal occurred: a "left" turn input resulted in a "right" turn output to the signals (assumed front and rear). This was initially unnoticed by the driver, as traffic conditions were dense. Upon beginning the left hand lane change, a check of the left mirror revealed a car overtaking on the left. Upon review of the turn signal, it was observed that left and right turn functions were reversed. As this event occurred in dense traffic, the driver was forced to nurse the truck to the side of the road and attempt to rectify the problem. Actuating the high/low beam control (on common turn signal stalk) rectified the problem for the time being. The truck was returned to its home address and then was driven to the dealer to demonstrate the problem. The dealer entered the problem into the system and a replacement control assembly was ordered. The dealer made no attempt to retain the truck due to potential life safety issues associated with the defective signal device. The turn signal subsequently failed in traffic, resulting in a minor parking lot accident. The truck was returned to the dealer and left there by the owner. Upon installation of the new controller, the truck was driven from the dealership and sold. The dealership indicated that they had replaced 4 or 5 controllers in the 2005 series trucks and at least one in the 2006 series.
