Possible stuck open thermostat, low coolant level, heater controls or restricted heater core. Replace t-stat first thing anytime there is a heating/cooling problem with the engine which also affects hvac systems.
I ran the motor to running temp. The big radiator hose was to hot to touch but both the heater hoses were barely warm. I had no problem holding Them in my hands. I held them close to the firewall. addendum : I ran the air pressure up to 100 lbs. It blew out something, Because I now have heat. Thanks tor the support. Tim
