My first post, so . . . be polite.,

The A/C does not work. Fuse is fine. I want to check the button switch on the A/C control panel. There is power to the switch (though light doesn't work) when engine is running and fan are on. I can't work out how to get the switch itself out of the panel in which it's fixed. Button is off and connector too, but I'm stuck with the switch body.
Who's done this and knows please?

Thanks folks.
