I have a 2001 ram 1500 sport. I have no heat blowing thru vents. Checked thermostat, flushed water thru heat core to check for clog, it wasn't. Took off blend door motor and checked plastic interposer ( heatertreater) it wasn't cracked. When I tried to spin the shaft to blend door it's spins back and forth freely. Shouldn't it stop when it shuts off one side?
