Retrofitting Heated Mirrors on a 325i Touring !

[Sharknose3]

Hi all,

I have a quick question,

Last time I did this I just tapped into the brown and blue wires at the back of the mirror motor and soldered on feed wires for the heated mirror glass on each side. This worked well.

Last night I tried this and when I switch on the ignition the mirror motor runs constantly until I disconnect the mirror glass.

I tried this with 2 x different heated mirror glass units and got the same result. The K7 relay is present in the fusebox.

Can anybody help?

Thanks Sharknose

Should be the brown and the black wires!
