Hi Guys

Hi it is commonly call a rear demister. It should have electrical connections at either side of the glass. One side is earth and the other side is 12 volts and current runs through the copper lines to heat the glass. Your car should have a no/off switch to control it somewhere on the dash. Hope this helps you out

It is an OPTION for Datsun 1200. For details see Defroster, section "rear defroster".

Hi DD

Thanks, is the wiring 12v directly going to rear window Heater lines as above DJF280's comments.the picture i am confuses having copper tube to the rear windscreen is it to take wiring there is it ? so what my mind is the heater lines gets voltage from the dash switch ? correct me if i am wrong

thanks

it connects to the copper wires (traces) on the back glass. You should find two of the traces going off to the side, that is where the wiring connects.
