Ford Mondeo V 5 year 2012-2021 how to fix/repair heated mirror glass after he fell from the plastic support or it is broken. The easiest way is to replace this plastic support with a new mirror that is already glued to it. If the mirror detached of that black plastic no worries is a common problem with many brands for car manufacturers like Volkswagen Golf 5 and 7, Opel/Vauxhall Astra H and Corsa D, Audi A4 B8 Facelift, etc.
To prevent this thing, use the mirror heater only when is necessary, from time to time check if the glass is glued on the whole surface, or if is shaking when driving the car. If this happens, take off the glass carefully and you can glue it with any glue that can withstand low or high temperatures. Be careful how much glue you add because the heating in the mirror is on black plastic and if the layer is thick it will not heat the glass.
