If folding option is used as a default (goes automatically in when car locked), wired often wear and broke where they bent. Heater element is integrated on mirror glass, passenger side replacement or 2nd hand mirrors are quite cheap because they have not dimming option.

Do I buy a new mirror with new heater element and fit in existing housing or do I have to buy complete replacement wing mirror including housing etc?

Just by a new mirror glass, a new mirror complete would be loads of money.
