Re: heater blower fan works and blows air perfectly
Look for a loose vacuum hose that should be attached to the damper mechanism for the defroster. You'll have to get way up under the dash to find it with a flash light. The hose may be attached but brittle, in that case a bit of electrical tape wrapped around it may help.

check the actuator motor on the heater sounds like the motor is not directing the air as it should. The motor is in the center of the truck inside attached to the heater and has arms on it to move the heater and ac doors.
I assume your heater setting is electric control, if so either your defrost and floor heat switch failed or wire problem.
For the air not hot, check the heat control valve on the top of the hose it should be in front of the firewall. I don't know your car is using mechanic valve or electric control valve. Anyway check there first.
the blower relay switch controls the blower motor,this sounds more like an air blend switch on the heater control head on the dash,not making the switch over in that switch.it could be the air blend door motor on the heater duct under the dash on the passenger side.this can be checked with a scan tool that has the capability to communicate with the bcm computer on this car.
heat sensor for radiator fan switch, thermistat,water pump? Does hot air blow when moving? does car over heat when sitting idling for over 10 minutes. If so check fan first, then water pump. last cause thermisat
It sounds like you have a blend air door stuck. This is in the housing of the heater a/c blower unit under the passenger side of the dash. There is a motor on the top of the housing that could possibly be stuck or on working.
