REPLACED HEATER CORE, THEROMOSTAT, WATER PUMP AND HEATER CHECK VALVE. THREE HOSES GONG INTO CHECK VALVE ARE HOT. HOSE FROM THE WATER PUMP WARM. COULD THERE BE A AIR POCKET WITHIN THE SYSTEM KEEPING HOT AIR FROM INSIDE THE TRUCK? IF SO,, HOW DO I GET THE AIR POCKET OUT? COULD IT BE POSSIBLE THAT THE LINE FROM THE WATER PUMP IS BLOCKED? THANKS FOR YOUR HELP IN THIS MATTER, NEED HEAT! MUFFDIVER

I might have an answer for you.
But i have few questions first.

Did this just start? Or did you buy the truck
like this?

When did it start doing this.
You didnt say if the heater fan works
or if you checked to see if its locked up.
Did it used to make a noise once?

Did you replace the Heater dial?
Iv have to replace my heater dial twice in a year.
Comes to find out i need to replace the WHOLE
electrical mount with speed dial, temp dial and the
positional panel its self.

Look into that also.
