Evening to all

The electric driver's mirror on my 2006 facelift SRi is not working, i.e. no mirror movement & no heated mirror function either. The passenger side mirror works absolutely fine, both movement & heat function.

I'm the only person who drives the car and I almost never use the electric adjustment so haven't noticed this before

Before I go blindly poking around, does anyone have experience of this particular problem, and if so how did you solve it?

Any suggestions/advice gratefully received.

Many thanks in advance
