I believe your problem will either be a stuck or defective blend door panel, blend door actuator or restriction inside the heater core. An infrared laser thermometer is a great tool. If you can borrow or buy one please do so. To test the heater core you need to verify that the temperature going in and out of the heater core is similar and the temperature going into the heater core is similar to the engine temperature.

-Looks like the heater valve not completely closed.
Check it out and replace.
Good luck

Hello, Sounds like the flap that controls the cold air and hot air duct is not working. One duct pulls air through the heater core where the other duct draw air from the outer vent. If that flap is not working, allowing you to pull from the heater core duct, then either the switch/lever that controls the flap is faulty (more likely) or the flap is stuck (less likely). Hope this helps.

Could be the blend door under the dash. The doors direct air thru the heater core and out the vents.

Does it take a long time to warm up the engine?

the heater vacuum motor and lines needs to be checked.Also get the blend door checked.

blend door actuator failing and sticking on cold setting

There is a actuator on the right side of your leg while sitting in the drivers seat under the dash. It has a plastic rod for actuation manually actuate this diverter and should be the problem.
