Dodge over all is a nice running strong truck but little problems like my fuel pump failing because of losing power after spending $1000.00 dollars replacing almost everything related to fuel problems It turned out to be a loose ground wire for the rear tail lights that caused the fuel pump to loose power. Now i am told that the blending door inside the heater box may have a 10 cent plastic connector that goes bad and would require 12 hours of labor to replace I've already replaced the water pump and thermostat and now would like to drill a hole and force open the blend door and jam something in it to keep it open forever. I don't know where to drill this hole so i don't damage anything inside besides that blender door. vidyagati
