Heated rear window

[c13tay]

Early C180 - heated rear window has stopped working - yellow light in switch illuminates as it should when pressed but no action on rear window. Noticed that on tickover rpm doesnt drop slightly as it used to when switch is activated. Any ideas

Have you checked to see was there any obvious breaks in the wires going to the screen.

The fact that its totally gone, would suggest it the main wire. The switch for the relay is usually on a different fuse to the power to the window itself. So ! would suggest you check the fuse thouroughly. Its usually a 25A fuse, serving only this item.

No obvious break in wire

Fuses ok - relay is clicking when switch is operated although after removing and replacing the relay the click was significantly louder

will steam up the window later to check if its now working
