Hi guys, it appears the green LED that glows from behind my headlight switch is dud.

What's the easiest way to get in and check this out?

Remove entire pod and get it on the bench? Or can the switch be removed with the rest in situ?

If it is a MK1 Tuscan then you remove the top cover (two screws at the back then lift out watching out for the cables).
Depending on the age of your Tuscan there are either two cables (change up lights and intermittent wipers) or three (those plus back light adjuster knob) to disconnect.
I would advise taking pictures as if you connect one, like the back light cable, incorrectly it WILL blow a diode on the dash PCBs.
Remove the light switch knob (small Allen grub screw underneath the knob)
I seam to remember that you have to remove the dash bracket screws that go into the back of the alloy dash facia and then it will move out of the way.
After doing this there are about two screws and two standoffs (which the dash bracket screws go into) which will remove the PCB that has the light and fog-light switches on.
Be careful of the ribbon cable that connects the light switch PCB to the dash PCBs as mine had a fractured solder joint that I had to re-solder (which is why I had to take the light switch out).

I did not have to remove anything else when my light switch cable had a problem.

Reassembly is easy if you took notes/pictures of when you took it apart!

PS. The LED is likely to be a surface mount one, so make sure that you have a small tipped soldering iron to replace it smile
