In the last fortnight or so, when I open my Veccy's tailgate the button sticks in. I've tried oiling it and spraying WD40 but this doesn't work. I can only imagine there is a spring somewhere that isn't as strong as it should be.
I free the button up by giving the chrome plate next to it a big wallop. Sometimes it can take three wallops to free it up. I suppose soon enough I'll have to replace it but in the meantime I'm stopping like Fred Flintstone at amber traffic lights in an effort to get the guy behind to replace it on his insurance.
