W203 Heated Door Mirrors

[kitkat]

Hi there, my N/S heated door mirror has stopped heating. All other electrics to the unit are OK (folding/adjustment). Can anyone hazard a guess at what's gone wrong? Any assistance greatly appreciated.

It could be a broken wire within the mirror, or the heater has packed up. wires do break when they are folding all of the time

Wow - super quick response - thanks Malcolm. Can you signpost me to some resources that will detail how to take the thing apart and begin the diagnosis?
