2001 Dodge 2wd 2500, V10 automatic. I have very little heat from the heater on this thing. Checked for hot coolant getting to & from heater hoses. All seems good. Is there any heating problems common with these trucks? Blend door not closing? Temp switch bad? The thermostat seems to be working OK. My last truck, an 87 D250 had great heat. I like old fashioned cable operated heater controls, you could "feel" if there was a problem, this electronic stuff, you can have it!
