Hey guys I'm having a problem with my multifunction switch on my 03 Dodge Ram. I replaced it and worked fine for about 2 months until recently I shut the truck off and went to start it back acted like the battery was dead. Noticed a lose terminal. Fixed that and noticed the switch acted like it went out again. Symptoms of headlights and taillights constantly on even if switch is off. No brake lights no wipers or washer fluid. No brights blinkers or hazards and no ext temp gauge. The dash acknowledges blinkers brights and hazards but doesn't actually work. Need some help.
