Heater problem
1989 Nissan Truck 4 cyl Two Wheel Drive Automatic
----------------------------------------------------------------
I can't figure out why I get no heat in the cab. Rad is good , antifreeze is topped up , new thermostat, heater core is good, heater hoses are new. Appears to be no blockage in lines. Somehow I'm not getting any flow through the heater core. Any suggestions. Thanks.

If it has one check the heater control valve
