Hi, I just replaced my radiator and bled the system also flushed the heater core. But now I have noticed that my car doesn't blow hot any more. I usually never use the heater but I may need it in the next few days. When I am using the A/C and crank it over to Hi there is a few seconds where it blows hot then it just becomes warm. Is this a blend door issue? If so is there a way I can trick the system into working correctly?
Thanks in advance.
