2001 Transit strange behaviour

Grimly Curmudgeon laid this down on his screen :

Could it mean a door has not been fully and properly closed, due to ice?

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember Harry Bloomfield saying something like:

It just locks and unlocks immediately, in that case.

Weird thing. An hour or two later I went out to try it again and it's back to normal, having touched nothing.

It happens that Grimly Curmudgeon formulated :

There you go then - jammed up by ice.

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember Harry Bloomfield saying something like:

No, the locking was working ok during the oddness. One thing I did notice - as I was pulling the frozen door open the interior light flashed on a couple of times, as the door contact made and broke when the door stuttered on the frozen hinges. It was immediately after that the winkers started playing up. In light of the other post about the Mondeo alarm and putting it into test mode, I suspect that something happened in the ECU, causing it to have a bit of a wobbly.

Or the switches are freezing.

Had a similar isue on my relay van its frozen contacts and locks , the locks and electronic ciruitery operate from a pulse from one of the many ecu units ,

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember "Duncan Wood" saying something like:

Oddly, the switch on the passenger door isn't a button type - I wonder if there's a reed switch under the rubber bung.
