One problem related to ignition switch has been reported for the 2006 Dodge Ram 3500. The most recently reported issues are listed below.
When using the turn indicator, either the opposite indicator comes on, or neither work. Also, the windshield wipers don't work properly. They seem to operate randomly (e. G. , work at high speed with the switch in the off position, or don't work at all with the switch in any position). It appears to me that the multi-function switch is defective. This problem nearly caused an accident while I was driving at highway speeds (60 mph)during a rainstorm and the wipers wouldn't operate. I had to drive to the side of the highway and shut off the ignition switch to resolve the problem. A less experienced driver may have had more severe consequences.
