I'm aware that in most cases when the turn light is not functioning all it needs is a light replacement, however, the dealer said it wasnt so in this particular case because my problem is not pertaining to the light itself but to a problem with the whole mirror assembly and that to get the light working again I have to replace the whole mirror assembly. I dont understand why you would need to replace the whole mirror assembly when the mirror works perfectly except for that light. Most people tell me that if the mirror can be moved around perfectly there is no need to replace the whole mirror, that I can individually just replace the non-working light.
