The heat in my 2000 Sierra is not working. I replaced the thermostat and made sure that all the fuses were good. With the truck running, I can take off the lines that lead to the heater core(with no coolant coming out), Could it be that my water pump is not working? P.S. the temp gauge is only going to 200.
