The passenger mirror (Manual) on my Class C Ford F-350 is loose where it attaches to the arm, and vibrates out of place so it is unusable. Any idea how to tighten it?
If it is a Velvac mirror,which it should be,there is a adjustment at the end of the arm,use a screwdriver to unscrew the cap, under it you will see inside the opening a hex screw I think a 3/8. turn it to tighten the mirror head.
