Mk1 Mr2 Rear Fog Light Switch

[Warwick79]

Hello. Can anyone help me with this one.

When my car lights are on......should the rear fog light button still glow/illuminate in the dark when not activated? It is just that the rear heated window button on the opposite side of the steering wheel glows when not activated so I assume the rear fog light switch should also light up. Obviously when I press both of these buttons they really light up to show that they are activated ...but there is not a dim glow on the fog light switch like on the rear heated window button.

Is there a slight fault with this button on my car?

I'd really appreciate any help.

Thank you
