Ramco Mirror Switch Assembly
Have you tried calling Ramco directly? I recently had to replace the upper movable mirror due to breakage and called Ramco on the 800 number in their literature. Person on phone was very courteous and helpful with suggestions and technique for replacement. Result new mirror next day via UPS and installed a short time later. Sorry I don't have 800 number right at hand but can get it if necessary. Good luck.
