No nearside rear lights or front side lights with boot closed!

Hi,

I recently started to get a positional lights error message on my 2010 S-Max. All bulbs are fine and disconnecting the battery for a while made no difference. I've just noticed that if I start the car with the boot open all lights work fine. Slowly closing the boot will cause the nearside lights to turn off just before the boot catch touches the car. Anyone seen anything similar to this before? I'm wondering if its related to the wires that run from the top of the car into the top of the boot - can you just pull those wire sleeves/grommets out or is there a clever way to remove them without causing any more damage?!

edit: I pulled out the nearside wiring sleeve from the top of the boot and the car but couldn't see anything obviously wrong. Strange that the lights will only turn off at a certain point as the boot door closes (almost closed but not yet touching the boot catch). Could water somewhere cause this?

So it turns out I looked on the wrong side. The left hand side was not quite as pretty. Looks like this is a fairly common issue on old S-max's. What have people with similar issues done - are the heat-shrink butt connectors the easiest way to repair?

Was this found in the wiring loom between the car and the boot it’s self?

Due the need to maintain as much flexibility as possible in the loom at that point I would avoid the use of crimp connectors.

Those wires that are badly damaged you need to cut, slide some heatshrink tube on and very carefully solder the wires together. The wires with only slight damage maybe better just wrapped with electrical tape to avoid the need to join.
