When I put air vent button on the setting that blows on the feet and defrost vents, then switch to the button that blows to the feet and and center vents, the AC kicks in. This happens every time. The ford tech says this in normal and is programmed to do this. He said its to kick in or lubicate the ac bearings/whatever.
I think it is a programming error.
Any experience of thoughts on this?

 

go to a different garage and get a 2nd opinion.

 

now that i think of it when i first got my f150 (2008) certain vent setting would make air come on.. but once i set vent setting to a certain setting and turned air off it hasnt done it since. Now air only comes on with defrost or if i turn it on.

 

ya, may do that. but the nearest dealer is 4 hrs away. Price to pay living in the north. I will bring it up again with the next oil change

 

Do you have the digital HVAC controls? The A/C is almost always running in mine, unless the setpoint is very high.

 

It's normal. Anytime you go to any setting with defrost the A/C will cycle to dry the air. Going to the dash vents and floor will let you choose if you want the A/C or not.

 

My 07 does the same thing. Plus I have auto control which does it too. I just switch off AC if i dont want it.

 

it's simply a self-lubricating system. if it doesn't turn on, it doesn't lubricate.

 

I have a 2008 with digital climate control and it does the same thing, i just shut it off.

 

That's the same thing I've been told
