Mirror question again: I have a 1999 Miata, perfect, all original. It does NOT have folding mirrors, it DOES have electric mirror adjustment. The adjustment does not work unless someone "helps" the mirror glass move. Do I need a new switch? Or something else? The car have never been wrecked and it has never been into a dealership service department. I am a retired ASE Certified Technician. I've had a stroke and can no longer do my own work. I have a great independent mechanic available.
