2007 Air conditioning - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

My 2007 Ranger has eternal air conditioning... meaning that when ever the air control is turned to any of the vent settings to the right of "off", the air conditioner compressor turns on and cold air comes out of the vents. The only selector position it does not happen in is the first position to the left of "off" just beofre the air condition and max air settings. I brought this up to the service department where I bought the Ranger and they told me it was normal, that the new compressors run all the time. I find this hard to beleive. If this is true I will first have to cool the air before I heat it in the winter. Also, If the compressor is always on (lubrication is the reason given when I questioned this), why not in the first poisition to the left of "off"? Why does it turn the compressor off when "off" is selected? I feel that they are not being honest about this. Can someone provide me with information to confront them about this with more knowledge?

Please e-mail me at mhaines@ideas-corp.com if you have information.

Thaks,
Mike

I have a 2005 F350 Super Duty and the compressor is on all the time, unless the switch is in the off position. Even when the fresh air setting is selected, the compressor comes on. This seems like a waste of horsepower and needless hours on the compressor, but that's how it works.

The dealer had no answer but other truck owners have confirmed this.

It is a real waste of gasoline as well. I watched my ac compressor on each setting and it ran on all but two. What's up with that???

The A/C is supposed to come on in all positions except Off, one position to the left and two positions to the right of off.

The compressor comes on (same for all my vehicles) only when on a 'defrost' setting or when I turn the A/C to 'on' (of course). Even the 'defrost/floor' setting the compressor turns on. Just be sure when you shut the vehicle off that your fan setting is set so the compressor is off when you start the vehicle next, it'll save wear and tear over time.
