Vanity Light Not Operating At Times
On the above models, if you receive customer reports of the vanity light not operating at times, make sure the sun visor is fixed in its support clip. When
the sun visor is not fixed in the support clip, the electrical contacts will be beyond their operating range and the vanity light will not function. The sun
visor must remain seated in the support clip when using the vanity light.
Note:
This loss of function should not be mistaken as a defect in either the sun visor's electrical contacts or wiring. The sun visor and vanity light are
operating as designed and should not be replaced.
