Wow, that's funny! I don't have auto on the pass. side. Mine is a 2010 March build. We should list the month build as it may be a new introduction. Mine is a job 2 having the sync mic in the headliner fwiw.

 

2010 XLT Sept or Oct build, only driver side auto, both printed on switch and how it works...i wish they would put it on all of them, doesn't seem like something that would cost that much at all to add...

 

yeah i wish mine worked on both... it says auto on both they both should work... but nope only the drives does

 

I'm reading all of this and maybe consider myself lucky. Auto works from driver's side. If a passenger is sitting in the passenger seat, all they do is puch the switch to the bottom and it auto drops the glass all the way down. If they don't push all the way down then the window only goes down as far as thgey hold the button down

 

What is your build month?

 

Frankly, I don't know...someone tell me how to determine the month and I'll check

 

Bottom of driver door when open look at the striker side. Month and year will be on it.

 

anyone else got any input on this??? the build date on mine is aug 2009

 

Mine is a build date of Dec 09 and only has driver side auto down. FWIW my 2010 Stang has auto down on both windows so I am sure it can be put in. They are the same switches as in the F150

 

Wife's '07 Navigator -- Auto Up and Auto Down, Driver and Front Passenger
My '10 SCREW Lariat -- Auto Down only, Driver Only

My previous truck, '05 Titan and my wife's previous '04 Escalade both had Driver/Pasenger Auto Up and Down. My Titan even had Auto-Down Both from the key fob, so you let out the hot air before you even get to the vehicle. I really miss that feature.
