think I have it wooped..drivers' side visor kept falling down & lexus wanted $500 to replace. problem was that the visor was loose on the shaft where it attached to the ceiling. i poked a hole through the visor close to the shaft and installed a screw, washer and lock nut and tightened it down to 'squeeze' the visor against the shaft. it worked! and because the visor fabric is thick, the screw & washer assy. is recessed into the fabric and does not show that much. i placed the nut on the top side of the visor. wife's happy and hope this helps.
