Could get no heat and found out the radiator was plugged pretty bad, so I have replaced the radiator, thermostat and heater core. Now I get some warm heat when running heater but not real hot and I get good air blowing when switching control to defrost but it stays cold. No heat. Not even warm air. Any suggestions?

L hvac fuse inside car it may reset your actuators item 2 and 5 in pic. These control heat/ac. Pull fuse with key on for 60 seconds then reinstall. Otherwise you'llneed to see if actuators are getting power.
