The heater flap, or blend door, is difficult to replace with OEM parts supplied from Ford. There is an aftermarket kit that makes the job and cost significantly easier at heatertreater.net or on the Ebay listing.

The block heater is standard on most Trailblazers. The cord is attached under a flap against the battery.

It is inside the HCAV housing under the dash.
I found mine through the inspection flap behind the driver's side wheel, hanging by the frame.
Like most cars. The heater control valve is located inside the closed compartment with the heater core and the and the AC condenser. It is a door flap that seperates the heated air from the outside air, or the AC air.
this is my truck and i have exhausted my options i have also replaced the thermostat. It's not just the dash vents it's also the defroster and floor. The heater cor works fine and the cold/hot cable is still connected on each end and the vent flap works to. please give me some suggestions. E-mail me at biddle26@yahoo.com thanks

Check the information below and follow the link to a video showing how to access and repair the blend door. The Heater core is difficult to replace on the F150 since it is buried in the plenum box. Getting to the core involves removing the steering wheel, steering column, complete dash panel, evacuating the AC, draining the radiator, and finally removing the heater box. Once you have the box out(8-12hrs), the core is simple to replace. You want to be sure that the core is the problem before you undertake this process. If there is a strong smell of antifreeze in the cab or a puddle of coolant on the floor, the diagnosis is easy. Check that the radiator is full, not the overflow tank, the radiator. On a cold engine you can remove the radiator cap and check the level. It should be full. If there is air in the system it will affect cab heating and engine cooling. Another good check is to feel the two heater hoses going into the firewall from a cold start. The hoses should warm up at about the same rate and get uncomfortably hot-close to radiator temperature. If the core appears to be OK, the next concern is with the blend door that diverts air through the heater core. This is a common failure on the F150. We have a video posted on our web site that shows how to diagnose and repair the system. Please follow my user name back to my bio page to find a cut-and-paste link to the web site.
