No heat
Asked by Zach Dec 13, 2018 at 03:49 PM about the 2006 Ford F-150
Question type: Maintenance & Repair
I have a 2006 f150 with little to no heat. I’ve
checked coolant levels, checked blend door
and actuator, flushed heater core, and both
lines on core are hot. What am I missing so I
can fix this??

If both lines are hot going to and from the heater core, then coolant is flowing through it. You can have a partially clogged or closed heater control valve. Check both lines going to and from the core. The valve is usually on the supply line. Remove the hose from valve on the supply side and make sure coolant is passing through sufficiently when heat is selected on the dash.
Looked today to see and test heater control valve and from what I see there isn’t one on the truck. Is there any location it could be at that I’m missing?
Go to a site like auto zone and plug in the year, make and model of your vehicle. Then search for heater control valve. It fits between two sections of the heater supply line. Mot are black plastic and are vacuum operated. They should supply a photo to guide you.
