Push the release back towards the connections, turn the knob to the right 90 deg. then pull on the knob. It should come out. It is a challenge as it is in a tight spot and mostly done by feel. Once the pull is out, a small pair of needle nose pliers can be used to catch the notches in the switch mounting nut to remove it. The switch can then be lowered below the dash to do testing. I included some wiring diagrams in case you dont have them. If not clear, send me a PM with our email and I can send you the documents via email.

Thanks so much for all that info. Especially the method to remove switch.
I have a large laminated wiring diagram by Classic Car Wiring. Very clear and color coded. The supply to rear lights is common with dash lights and dimmer. may try the easy option first with by pass dimmer as the lights are dim anyway and hardly need the dimmer.
Its a shit of a spot to try to work on and switch removal would make access easier.
Thanksso much.
