no heat

my 96 v6 rodeo has no heat , i've installed a new thermostat have tried flushing the whole cooling system , the lines to and from the heating coil are hot , water pump is good ,i checked it when i changed the timing belt. any ideas ,do i just not flush it out well enough ?

the rad is probably plugged.

try searching here, that has been a couple of recent posts.

i flushed the radiator seems like it flows thru good

i flushed the radiator seems like it flows thru good the temp gauge reads pretty low

i figured it out , the blend door is stuck in the closed position due a broken pin from the heater control
