There is no valve on these trucks - coolant flows through the heater core at all times. Check for a plugged heater core. Disconnect the heater hoses from the engine side of the firewall, and flush the core with a garden hose. (Use some spare lengths of heater hose, running one into a bucket. Flush it in both directions).
Next, you should check the output from the water pump. Stick both heater hoses into a bucket, and have someone start the truck. You should get good flow out of one of the hoses.
