heater will blow out of all vents except the ones that face you.2001 harley f150.thanks darren

 

Do a search in the HVAC section. Look at blend door problems.

 

sorry mate ,only had f150 here in the uk for approx 5 weeks .whats the hvac and what is the blend door.sorry for being so vain.i see your from mount juliet.i was there last june trying to get employment with my sister in law who lives in georgia.i love the us.darren

 

No problem mate! When you back out of this forum selection, its the 3rd one down in this same section.[HVAC- heating and A/C]. The blend door is part of your air system in the dash that controls air flow. Do you have one of them passenger door steering wheel trucks? When you come back look me up and I'll buy you lunch.

 

mate ,yes its left habd drive if thats what you mean.do you know a road construction company in mt juliet called jones bros?they were the ones i visited ,nice area my wife and i loved it there

 

No. The blend door is related only to temperature control, not outlet selection.

Outlet selection is by vacuum motors that move diverter doors inside the plenum. Each position of the selector switch corresponds to a specific combination of vacuum motors and doors that get moved to specific conditions. If you have a electronic climate control, these selections are made by the control head which controls the vacuum motors.

Make a chart showing each selector postion and where the outlet air is actually flowing. From such a chart, it becomes easy to isolate which vacuum motor is not functional. Your owner's manual should give you the desired outlet for each postion, we need to know the actual selections

Also, let us know if if you have the manual or the automatic climate control.

Hey Darren, Listen to what Steve is telling you. Thats why I said to go to the HVAC SECTION cause I'm learning too! I do know who Mr. Jones is and about his company. Good guy in the community.

 

My 2003 supercrew with auto climate only blows air to the defroster when in automatic. It will switch to panel when selected however it will not in any case switch to floor even when the floor button is selected. I have read all of the posts on vacuum leaks but could not find it. Took it to the dealer and they said that the control head was bad. $ 800.00 was the estimate. Ouch!
Where is the control head and why so expensive?
