I'm happy to replace the mirror no worries, but does the specified issue require part replacement in entirety? All other buttons work on the drivers side door panel, perhaps it's a loose connection? Airbag light - could it be this 'clock spring' and if so, any thoughts for a fix? I've also noted an odd dullness to the headlights - wondering if this is moisture or simply needs the units replacing courtesy of eBay etc.? Thanks! Adam.
