Hello I have an 05 dodge ram 2500 I was having intermittent blower motor problems and I looked at some of the forms and chase it down to the ignition box in the steering column the day before I did this I lost blinkers fog lights wipers wiper spray and tail light blinkers . But the blinkers in the gauge cluster they light up but it's not signaling the headlights or the taillights to signal i'm going to replace the ignition box and see if it helps but all problems are located in the blinker module on the steering column any suggestions on what I should do here or has anybody ran into this problem

 

Sounds like a Multi-Function Switch issue to me...
