Used my wifes 13 xf last night and found that the cruise engagment switch is loose in there. Can pull it out as far as the airbag allows. Had a look at some used ones and it appears there is a brass "nut" for a screw on the back side. Anybody know how the thing is held on? Hoping I don't need to have the airbag removed to get at it (if that is the case anybody have a source for the airbag removal tool?
