Ranger heater question
I am having a bit off a heating problem with my Ranger.Its a 2007 2wd 2.3l engine. When I turn the heat on an turn the dial clockwise its more like an air conditioner then a heater. Something tells me the switch is not doing its job switching from cooling to heating. Any ideas here. Thanks for any help.

Anybody have any input at all? I wonder if theres another forum I could get some answers from. Seems like the site is not as active as it used to be. I used to get answers pretty quick in years past but any more its pretty dead.

I don't venture here much, but can say that most FoMoCo vehicles use what is called a 'blend door' to modulate the temperature. It will mix heated air from the heater core with cooled air from the evaporator [in DEFROST or MIXED mode] to meet the desired temperature.
My old Ranger has cables, most later models use an electric motor [which has a high hinge failure rate] to move the blend door. Search on "blend door" for a better description.
The way to test for heater operation is to put the mode control to floor position. That should disable the A/C compressor. You should then get hot air from the heater, and if you don't, the blend door may be broken or stuck in the 'cool' position.
Do the search...
