Did you have any of these issues before replacing the radiator and thermostat? If not, what was the reason for changing them?
So you removed your original question, but I think you were saying that the heater is not getting hot.
I believe this vehicle has a heater valve, make sure it is working properly and check that the heater core is not plugged.
My 94 B3000 had a broken hot/cold Switch, pretty much a wire broke off and would'nt switch from hot to cold till i Glued it back on. pretty easy to tell if its broke just compare how hard it is to Pull the other lever to the hot / cold lever. if it feels loose it might be your problem.
