I have a 85 Ramcharger and the heater isn't working. The guy I bought it from said he just went through the heater core. I took the radiator cap off and started it up to make sure I was getting flow through the radiator and I am. The only other thing I can think of is maybe the thermostat. Does anyone have any advice for me. It's starting to get cold here in Minnesota and I need the heater working.
Any help would be appreciated!!!
