I am having a problem with the door sensors. I think it is the rear hatch or barn doors.
I can't seem to clear it with electrical spray cleaner. Where are the sensors in the doors?
Also, the seatbelt alarm goes off at random when the vehicle is parked and running.
Thanks for any help I can get with this. Taking off the neg battery connection will get old real quick.

First, the lower barn doors have no sensors in them. The liftgate has 2 sensors ... one on each side, and they're attached to the latches inside the liftgate. If I were you, I'd just replace them since those two are the easiest to reach. Unscrew the pull handle from the liftgate, then all the other interior trim can be pulled away from the liftgate ... they're held in place by little clips. WARNING - Don't let those little clips get away from you! (Ask me how I spent a couple hours searching my driveway, then finding the missing clip up inside the liftgate frame.) I unbolted the latch assemblies from the liftgate when I had this problem in my '01, which made it much easier to swap out the door-ajar switches.

Were your seatbelts fastened already? I have seen this happen ... have unfastened my belt when sitting still with the engine idling, and the chime goes off. Mine stops after re-fastening the belt. If your chime is activated while the seatbelts are fastened, then I'd have the problem checked by a dealer. |

Just a quick note to let you know I have successfully fixed, maybe temporarily, the door ajar problem. I decided to try the WD-40 method. It worked! I soaked 'em good and opened and closed the hatch a few times. Any chance this will last for a while? Only time will tell.

It should work for quite a while.
Here's another tip. I had a gunsmithing business for many years. When it came to WD-40, I called it 'The gunsmiths friend' not because it was so useful, but because everyone that used it on their guns would eventually bring it to me as unworkable and I would make some money.
WD-40 is a mix of light oils and waxes. The oils carry the wax in to the works and after the oil is gone, the wax stays behind and continues to lubricate.
In guns, and any thing else that have small, hidden, inaccessable places such as locks, mechnical watches, power tools, sewing machines, etc., the wax left behind builds up and becomes a cake, trapping dirt and getting gummier.
This can get so bad that a revolver that was brought to me one time took over a full second for the hammer to fall!!
Anyway, the point of all this is to suggest you use a different spray oil that does not contain the waxes to lubricate anything hidden or mechanical. I highly reccomend either Rem-Oil by Remington, or Birchwood Casey spray oil. Both are available at K-mart and Walmart in the sporting goods section.
I cring when I hear guys say they sprayed their wheel hub selectors with WD-40 to keep them from jamming!. The dirt it collects is a sure way to jam it up. |

What about Mobil One synthetic spray lube? I didn't realize Wd40 left behind a wax residue; I thought it left nothing behind. |

Mobile onew is (was) about the best lube you could find for all around work. I have used it on my guns and it does not have waxes.
Unfortunately, Mobil has dicontinued the production of the spray lube. If you see any, buy it. It won't be around anymore. |

I've avoided WD40 on my firearms mostly because I heard it will "creep" and possibly contaminate ammo left in the gun over a period of time ... will contaminate the powder and/or primer. Granted, I have only two pieces which are loaded 24/7. The others stay unloaded, and locked inside my 1,000 pound safe (that's 1,000 pounds empty).
BTW, I'm a NRA Life Member. Before other readers start to worry about conversing with a bunch of gun nuts .... er, I mean firearms enthusiasts ... let me say that when I carry, it's like putting on my seatbelt in the car or truck. I put it on with a prayer I'll never need it. |

Guys,
I have a varied background including firearms, law enforcement, and aviation. I tell you that to reinforce the WD40 remarks. It has its places, just not many. Now, having told you that I have both a question and a recommendation.
1 - Question - I just drove my wife to Tampa, FL from northeast Texas and she dropped me off at the airport and I flew back to DFW this morning. During our road trip we started having a lot of problems with our door warning light being illuminated and if I'm not wrong it may be related to the rear top door. Reading this thread, knowing my wife is in Tampa for two weeks, she's having this annoying problem, and this problem also complicates matters because our alarm system monitors the interior lights circuit (as I understand it) monitoring for a door to be opened; can someone point me to a thread discussing how WD40 (or any other type of spray lubricant) can be used to at least try to temporarily resolve this? :noteworthy:
2 - Recommendation - FAA approves the use of a spray lubricant for use on hinges, turnbuckle/cable assemblies, etc. The product is LPS (http://www.chiefaircraft.com/airsec/Aircraft/Chemical/Lubricants.html) and they make three different types: LPS 1, LPS 2, and LPS 3. The #1 is a penetrating thin spray (Which interestingly can actually be painted over.), the #2 is a bit thicker spray and is probably the best general spray penetrator/lubricant I have ever used, and the #3 is VERY thick product that (like as mentioned about WD40) also leaves a wax residue (I have no commercial relationship to the product whatsoever.). #3 would maybe be what you would put on things like drill press mandrels in your shop to keep them from rusting in a humid environment. Note: I do not recommend any kind of penetrating lubricant on a firearm because they demonstrably render at least some ammo inoperative by killing the primer and/or powder. With that caveat all the LPS products are outstanding (but not cheap) and I can highly recommend them all for shop use.
Thanks in advance for any suggestions regarding item one above,
Phil

[b]UPDATE[/b]
We drove the Excursion back from MCO this last weekend. The door ajar light was on intermittently. Today I was running some errands and the light was illuminated so I pulled into the local Ford dealership. The service adviser first started off spraying each of the door latch mechanisms with a spray silicone saying that will sometimes clean (something) up that is gunked up with dust. After spraying each he closed and reopened the doors a number of times. So, that appears to be an insiders trick to sometimes resolve the matter.
In this case it did not resolve the situation so they ran the Excursion around to their shop and had a couple of guys opening and closing doors while yet another guy used some sort of diagnostic tool and determined it was one of the two sensors in the rear upper hatch.
Labor (diagnostics and replacement) = $70
Part = $30
Total = $100 plus tax
If someone comes up with a brilliant way for people to diagnose this matter themselves I would love to hear it. For now it boils down to spray lubricant on the latches unless and until that no longer works, and then you have to go to the dealership...
