I have a 98' dodge ram 5.2 L. My truck warms up and the heat blows but its not very hot? Its only a single cab, it should get blistering inside.

Thanks for all the help.

schott was having the same problem I believe he said he changed his t-stat and it's working fine. I know my cab is nice and toasty warm and it is f'en cold here.

 

I would guess your thermostat is stuck open. Take it out and replace it with a 180 degree one. You might also look at your heater hoses to make sure someone didn't put a on-off valve on one of them, and the valve is off. Thats an old farmers trick to make sure NO hot water gets to the core in the summer, in case the truck didn't have ac.
