This issue started last year, but was less severe.
If I start my truck to warm it up and let it sit and get hot the front heater does not produce any heat until I start to drive.
The front heater core does not seem to be getting any coolant flow at idle. When I accelerate I can hear the coolant flowing through and heat starts.
This is not an issue with the rear hvac system.
Is there some type of flow control valve for the front heater core?
Thanks
