I have a 95 ram 1500 the temp gauge reads normal but i dont have good heat at all. so i dont think that it is a thermostat problem and cant think what else it could be. I was looking in the repair manual and i came across a water heater controll valve and was wondering if this could be the problem. If anyone has any suggestions please let me know last winter was cold!!

 

could be the heater core. any leaks in the coolant lines?

 

yea a small leak but both lines to the heater core get hot on each side
