2006 Dodge Ram 2500 electrical system problems

Tl* the contact owns a 2006 dodge ram 2500. Another vehicle cut in front of the contact's vehicle causing the contact to lose control and veer off the road. As a result, the contact crashed into a tree. The air bags failed to deploy. A police report was filed. The contact sustained injuries that did not require medical attention. The vehicle was not diagnosed or repaired. The contact stated that the parts were not available for NHTSA campaign numbers: 14v817000 (air bags) and 14v795000 (electrical system).

Turn signal will either not work or show the wrong side flashing (have almost been rear-ended), wipers wouldn't work properly or at all (go very slow or not move at all when on, causing me not being able to see when it's raining hard). Flashers won't turn on at all. Happens every time I need my flashers, wipers, and blinkers. Replaced the multi-function switch and all of the problems above are fixed. I still have the old switch and I have heard it's a common problem.
