I was cleaning my sn95 convertible and I pulled the sun visors down to dust them. When the visor came down the lights didn't light up , so I bought new bulbs and nothing, I then checked all fuses and any wiring I could trace and couldn't find a problem. I went to put the car in the garage that night and pulled my headlights on,then the vanity mirrors lit up. I may have been wasting my time as it appears that panel or headlights have to be on for the mirrors to light up...every day this Mustang teaches me a lesson !

 

It's haunted. Totally.
