Hi All,
Just a quick note to let you know how easy it is to change one of these, despite what the Gregory's manual says you do not need to remove the steering wheel.
All you do is undo the 6 screws on the underside of the steering column cover, lower the tilt adjust lever drop the column and the two halves should come apart.
Undo the two screws holding the stalk in place unplug the wiring loom and do the opposite to install the new switch.
Took me about ten minutes and is going to save me a world of pain as the old switch was stuffed.
Hope this helps
Mark
