I have just been to the local Toyota dealer and asked about this door mirror heater issue,a nice chap at service offered to have a look and checked the mirror and advised that there is no heater at the back of the mirror. So armed with the chassis number he checked with part department and pulled up my vehicle spec and it shows two models a normal version and a winter model. yep guess I dipped out again as mine does not have heated seats also it the normal sunny jap version. So that should end my saga.
I will have to breathe heavily on frosty mornings to clear the mirrors in future.
