The drivers side sunvisor on my 98 Boxster hangs down about an inch and will not stay in the fully up position. If I push it up, it will slowly droop down and stop after it has dropped about an inch. I've tried calling it names, threating it and questioning its heritage to no avail...
Does anyone know if there is a way to adjust/tighten the friction in the hinge assembly? I have the visors with the lighted mirrors.
