Four problems related to wiring have been reported for the 2006 Dodge Ram 3500. The most recently reported issues are listed below.
Wiper blade electronics will stop intermittently causing loss of visibility especially in severe weather conditions. This has happened numerous times despite use of appropriate DE-icer winter formula wiper fluid, replacement of the wiper motor, and multi-function switch assembly. The problem appears to be overload of the circuit when there is mild to moderate amount of ice on the windshield or when the steering wheel is readjusted downward causing the wiring harness to come loose. This has almost caused major accidents at least 2 and maybe even 3 times due to this issue. The problem occurred when driving straight at slow speed of about 20 mph due to severe weather and I was forced to stop when the wipers would stop working.
Rear turn/hazards signals do not work, front turn signals are fine. All fuses, wiring to lights, bulbs are fine. Trailer plug is fine. This problem is causing many other motorists to not know my intentions when changing lanes or turning.
Left rear brake light doesn't work. I spent $200 at two different dealership trying to get the problem fixed and was told that it would cost me an additional $1500 to fix the problem. Something called the tipm was blown and wiring was damaged. I have inspected the wiring and it is not damaged.
If you use your 2006 Dodge ram truck for towing a trailer, there is a totally integrated power module (tpim) in the fuse box that is not protected by fuses. So, if you hook up your trailer to power your running lights and there happens to be a glitch, the tpim runs the risk of being fried. It happened to me with other 42k miles on my truck. The regular warranty does not cover it and many, many people with 2006 trucks have had this problem. The dealer had to replace mine. The part was $700 and labor was over $200. This set up is unacceptable in a vehicle that is built for towing. There is a software flash to up the amperage of the circuits but it doesn't completely fix the problem. Dodge needs to provide a recall to install more protection between the trailer wiring and the tpim.
