ok try this remove the cap from the overflow bottle then rev the engine up to 1500 rpm and hold for a few minutes see if the heat start to work let me know . the problem may be the heater control valve or you have air in the system

Customer: replied 2 years ago.
I did remove the bottle cap and I see little better hot air come out,
I will try tonight, look is gone to be colder
Expert:  Clifton B. replied 2 years ago.

to see like you have air in the coolant system at this point you will need to get the coolant system flush and bleed to get the air out so the system will blow hot again .
