Hello dum question but how do you get the washer button off of the washer wiper switch on a 1970 i tried small screwdrivers and the smallest allen key I got with no luck? am i missing something i can bearly see what is holding it

 

Its a small allen screw. I have to use a magnifying glass to see it clearly so it is small. but if you have the right sized allen wrench it should loosen and allow you to remove the ****.

 

Thanks got it
