Question about 1998 Dodge Ram 1500 4WD
2002 Dodge Ram heat does not come on when truck is not moving. When trruck moves the heat is very good. Was having heating problems, 1st thing that was done was to replace the thermostat, which I did & that did not fix the problem. 2nd thing that was done was to check & see of the heater core was stopped up and noticed that the right side of the radiator & the top hose was hot while the left side & the bottom hose remained cold. I was told that I needed to replace the radiator, so I replaced the radiator, this also did not fix the problem. PLEASE HELP I'm at a loss
So have you had heater core flushed, or tried to do your own flush on it yet? Just for your reference in future, when coolant reaches 190F approx depending on thermostat setting & thermostat opens, hot coolant from engine returns to rad for cooling via top hose, and cooled down coolant , from bottom of rad flows back through system, and process starts all over again. That said, it is not uncommon for it to feel cool at idle, because with any restriction in heater core from calcium, whatever, it needs that little extra RPM's to push it through better, increasing the flow, thus better flow, better heat. If you decide to do it yourself, let me know, otherwise have rad shop flush system, core & reverse flush core also, it tends to flush out more debris that way. It may not be like new, but should be much better.

You need to get under the dash board and remove the passenger lower kick panel. ther will be a small motor bolted into the evaporator housing. remove it and manually move the blend door. if the heat gets hot the you need a blend door actuator.
