heated mirror glass

[cd233u]

I know I will have to wire them in but can I fit heated mirror glass to my mk2 sharan with manual mirrors
hope to get the wire down with the adjustment rods

[Mirez]

Yeah should be easy enough to fit, the mounts are AFAIK the same so pop the glass and mount on and apply a fused 12v supply. Where are you going to grab the 12V supply from though, there isnt a suitable supply already in the door so you may have to run a new supply, relayed from the battery.

I was hoping to use the heated rear window
so turn that on and on come the mirrors

I think Mirez just meant there isn't a supply with enough power available within the door and you will have to run power through the dreaded gaitors in order to supply them.  I know on mine they come on with the rear screen, but haven't looked at the wiring diagram to see if they have a dedicated fuse.

[Mirez]

Yeah there is nothing in the door that can handle the current except the electric window wiring which would be a bad choice to wire into! The heated screen is a fine place but make sure you fuse the spur as the wiring and mirror pad will use a lot less then the rear window will.

what amp fuse would you use

[Mirez]

7.5amp should be about right
