I dont think that my heater on my 06 ram is working properly. I drove last night from laramie to cheyenne with the heat on the defrost/feet up as high as it would go with the fan on high the whole way. It only came out warm warm as in having bathwater sit in the tub for a few hours. In my old 02 ford running the heater like this would have chased me out of the truck? is this normal for the dodge or is something wrong? thanks
