94 heater issue
quick specs on the Dakota. 172K, AC, 5sp, 4wd, 318 magnum.
Finally time to get some work done on it.
It has a heater/heating issue. It does not get very warm, according to the gauge and what is coming out of the air ducts, not even 1/3 on the gauge. It has a newer radiator and I just installed a new thermostat. When I haul a load it will over heat. Going uphill the air turns cool and no matter what setting the controls are on it puts it on the floor vents, as soon as it levels out it goes back to the proper setting. Also, the heater control unit does not work 100%, it will not go to just face level, it has to be on floor/face. I have also noticed a slight hesitation when accelerating. It also has a small and unknown water leak. I do not smell anti freeze when I turn the heater on.
Could it be two separate issues or one? I am going to be putting on a new serpentine belt so I will check the water pump for issues, maybe just replace it anyway.
Does anyone have any ideas for another possible item that could be bad. This is a pickup that I drive in the winter for work, and the heater works so badly that it barely defrosts with windows.
Thanks.

my return line is hot, both lines are about the same temp, hot, but still able to be held. this was after driving 15 miles at 60 with the heat on.
Changed my serp belt, everything spun smoothly, that does not mean my water pump is not bad.
I think I am going to spend the money and have it checked out. Change the heater/ac control unit and backflush the system.
and who's brilliant freaking idea was it to have an allen and a bolt to remove the front brakes? That is just stupid.
I love this pickup.
