2014 Taurus PI HVAC randomly goes on AC / air re-circulation mode

Postby Mike B » Thu Feb 09, 2017 7:38 pm

Good day all !

I've got a strange issue with my 2014 Taurus PI. When I start up the car in the morning ( and I left the HVAC controls to heat, floor or face only position ), it will sometimes have the AC button on, and the air recirculation mode on as well pressed, when I didn't have those settings on prior.

Any one else's PI do this ? I'll assume the car senses it's cold out and automatically adjusts accordingly ? Then again, there is no "auto" button like in the civilian models, so I'd have no idea why it does it. And it only does this when I first start the car. Once the car's been running it stays in whatever position I put the controls in.

Yeah my 2015 does this. Randomly, in the mornings when first starting up. Mildly irritating, especially when its cold and I jump in to go to work. I will turn the temp and the fan all the way up, drive along for several miles until I notice the AC is on.

It may be running the A/C as a dehumidifier. Many cars use the A/C in defroster mode for that. Drys the air before there is enough heat to raise the dew point and clear the windshield with warm air.

Interesting. If I had the car set to defrost or something I could kinda understand the AC coming on by itself, but like I said, the controls were set to face / floor only. So, I found it strange that it would automatically put the AC on by itself ( along with the re-circulation mode ).

Well, I'm glad I'm not the only one with this issue. It hasn't done this in quite awhile, but the only times it DOES do it is when I first start the car in the morning. Next time I get an oil change I'll bring it to the dealer and have it checked, since it's still under the bumper to bumper warranty.
