Recently, when arming alarm it gives me feedback saying either door is open or rear clam switch is engaged. Not all the time.

Played with door switches (they are working fine) and clam switch but it's still doing it.

Car was washed last weeknd and I do have a drip tray. (Thought maybe water had got in).

Anyone else had this issue and know what it was?

Thanks

I had this mate , turned out to be corrosion in the connectors on the push switches , cut cable and fitted new connectors fine after that .

Are u referring to the doors. They seem to work fine. Interior light comes on when door open and off when closed?

Pull the connector off the rear clam switch to isolate it, if that solves your problem you can pick up a new switch off eBay for about three quid.

Talking of door switches, should they not also operate the interior lights?

My door switches clearly work as the alarm chirps when the door is open, but the interior lights do nothing, does anyone have a wiring diagram or know what wire I'm looking for so I can find why my interior lights don't come on when the door opens.

I had one of the door switches play up intermittently once, when the door was closed it only just pushed in the switch so I put a small bit of rubber hose on the end of the trigger (in effect lengthening the part that hits the door) which solved the problem. I then replaced the switch with a new one and all Been good since.

So when door was shut, interior light went out but still caused an issue?

That's right, the door would close, lock, light out, then at some random time in the night the alarm would go off. The door switches worked fine which is why I had trouble finding the problem. Then I noticed the door was closing fully before engaging the switch. I think maybe the switch wears down over time. Try putting something like a lump of blue tac on the door where it hits the switch to see if it solves your problem, if not you've not lost anything.

You could still have a faulty door switch, might be worth taking off the two door switches and disconnecting to see if it's cured? Just make sure you tie/tape the wires so they cant fall into the body.

Yeah, was thinking of just tKing the screw out as that's the grounding path. Will give it a go.

Yes it should but. Remember the interior light has three settings on its switch. 1. Off. 2.On. 3.Operated by door switch.

So don't go pulling your hair out trying to get the door switch to work if its on the wrong setting. Lol

haha I remember trying all the settings and just thinking that they were probably left over from when Ford used to install luxuries like lights that came on when you opened the door!

Lol, mine was locked up in the garage so fortunately never woke the neighbours! I think I went from fast asleep to standing on the drive (baseball bat in hand) in about ten seconds.

Just tried disconnecting door connections. Still doing it so it must be water somewhere. Thought it would have dried out by now?

As some have said the door switches (interior lights and alarm feed) don't always make perfect contact due to the hand-built nature of the beast. Some cars have had a shim added on the switch side during build to make this good. You'll usually see this on one side only. If so, a piece of sticky-back rubber on the door side can do the trick.

Drove car to work today (early morning) and when I got there and put alarm on I got the warning. Left it for a bit and went back to put alarm on and it's on ok now with no false alarms yet.

I suspect there was still water gathered somewhere after the wash and although it was in my garage for a week, it maybe wasn't warm enough to evaporate the water away.

It probably ok now as once I parked up from car being hot the latent heat from the rad must have dried it off.

Well I hope so.
