I popped off my driver side review mirror on my Subaru Legacy Wagon. The power mirror is still functional. Rather than paying for a whole new kit to be installed, I'm wondering if there is a way to reglue the existing mirror. Maybe take to an autobody place, or window replacement place that uses really strong adhesives? The mirrow is intact and the power is still functioning, its just dangling from the power cord. So I think its just a question of reglueing or replacing the whole kit. And if reglueing, what kind of adhesive? I'm assuming I can reglue now and replace later when I have the $$$.
if the plastic fell off the motor pack, chances are the tabs holding it on broke. you'll be pretty much done in that case. buy new mirror from dealer.
if the entire housing fell off car, then buy new housing.
