Welcome to the forum Robert1968,

I'll assume it must be a Jaguar or you wouldn't be here.

Dimming Mirrors are a regular issue but the Model, Year and additional functions in the Mirror (e.g. auto wiper sensor) makes quite a difference to available options.

Please follow this link New Member Area - Intro a MUST - Jaguar Forums - Jaguar Enthusiasts Forum to the New Member Area - Intro a MUST section and post some info about yourself and your vehicle for all members to see. In return you'll get a proper welcome and some useful advice on posting to the forum.
