A not so warm heater

hay guys my truck's heater is not very warm (blows luke warm) and the defrost works some what ok.

i figured on these old trucks it cant be to hard to get the heater working good again.

i dont know if it matters but my truck has the factory harrison ac unit (non working right now).

what should i look at or check to get the heater working good again?

at 28 degrees last night and a frozen windshild (i thought) thank god im not driving my truck tonight.
