Pulled the 14 Expedition out of the carport yesterday to take care of a leak that was dripping rainwater on the sunroof area. Parked it out front of the house, got some of the spray leak stuff that works (sometimes - I sure wouldn't get in a boat made with it) and sprayed the inside of the roof with it around the seam. Came back to the Expedition, put all the wife's Costco shopping trip insulated bags back in the rear of it and decided I'd try to find out why my mother-in-law was complaining about the door locks not work on the passenger side rear door. I couldn't find anything wrong with that door. I worked it with and without the keyfob lock button, worked it from the driver's door button (locking/unlocking) and got in the seat and shut the door. Locked it, grabbed the door handle and opened it. Locked with the key fob and then grabbed the lock "button" and pulled it up to unlock the door and opened it. I got out, looked at the child proofing lock "button" on the inside of the door and worked with it to make sure it worked. I wear glasses so I had to get at just the right angle (sun was bright, but not shining on the door button there) to see the right position for disabling the door handle inside. Put it there and made sure it all still worked and then moved it to lock and made sure the door handle didn't work - making sure everything worked as intended. Then I decided to repeat it on the other side. Heck, I just figured out the passenger side, right? I walked around to the drivers side rear door, opened it up, looked at the child proof button and saw it was in the wrong position. I thought, oh, she said back door but she meant the one on the driver's side. So I put that button in the same position as the one of the passenger side. Then I got in (little tight for me with the drivers seat back where I need it to be) and made sure I wasn't scraping the drop leg holster or FNS across the leather seat while getting situated and then I pulled the door shut and hit the key fob lock button. I grabbed the door handle and it wouldn't open. I hit the key fob unlock button and the door unlocked. But it wouldn't open. I did a couple repeats of locking/unlocking but the handle would not open the door. Well, only way to get out is to slide my big ass, feet, legs across the seat while getting my feet hung up on the windshield sunscreen I'd rolled up and dropped in the floor before moving the Expedition and my wife's umbrella. All while trying not to drag the FNS and holster (Safarilland 6305 with mag pouch attached) and not twisting my already aching back anymore than I can help. Took some careful "scooching" across the seats to get to the passenger door and get out. I go around to the driver's side rear door, grab the handle and it opens right up. I start checking for the method to get the interior door panel off since it's "obvious" something has come loose in the door. My wife comes out to get the mail and I start complaining the darn Expedition is already broke. She's standing there looking at the mail while I'm trying to explain why it's not working right. I show her the botton on the passenger door and show her how it works. I take here around to the driver's side to explain the problem and she's paying more attention to the mail than to me and that further aggravated me. I get her to look at me and look at the door and show her the switch and she says, "No wonder it doesn't work, you've got it in the wrong position." I looked at her and told her it was in the same spot as the one of the passenger side, I looked at it. She says, "It's in the locked position, look at it." I bend over, shade my eyes from the sun, get them to focus on the little embossed design in the rubber seal and sure enough, it's in the locked position. So, now I know Ford uses the same switch for both sides but they are reversed due to the change in position from one side to the other. I don't think she was shaking her head as she walked away reading the mail. I didn't look at her to see. It ain't every day my wife comes outside to point out what's wrong with a car/truck. I told her she taught me something and she told me I should listen to her more often (not about cars/trucks but about other stuff). Go ahead. Laugh. I did.
