Truck has had very little heat since I bought it. I have changed thermostat twice. 195deg. Burped the heating system and have a piece of plywood in front of the radiator. Working the truck. Like going up a steep hill. It will blow heat, but it can idle all day and not be warm in the cab if it's under 30 degrees outside.
Someone told me about changing a "Heat modulator valve" or" Relay" located on the passengers side fire wall. So far I haven't found this Valve/Relay.
Heat went out in the start of winter. Replaced the thermostat but that wasn't it, determined it was the heater core that went bad. I was not going to pay that much money to get it replaced so I stuck 2 pieces of cardboard in front of the radiator to make the engine warm up faster so I could get some excess heat from that.

Any Ideas would be great.
