Welcome. You should inspect the wires where they bend when the boot opens and closes near the hinges. Likely to be a broken wire with an intermittent contact.

Thank you I’ve messed with the harness that houses the wires and it looks like when the boot closes there is plastic retainer clip that attaches to the boot strut how ever when this closes it seems to bend the wire seems to be very poor design 😩.
I’ve managed to snap the plastic bit unintentional I may add and moved the wire around and it has come back on how ever it came off again so it’s definitely something to do with the wire. Will
I need to be a electrician to sort This problem.

If you can access the loom and remove the fabric tape you can look at the wires inside. Depending on what you find you may be able to solder or crimp the damaged wire. Just make sure all wires are insulated and placed back in the correct position so they are not damaged when the boot open and closes. You’ll need some insulation tape and some fabric loom tape to restore the factory appearance. Or just ask an auto electrician to take a look.
