Rear demister problem

[shaun_richmond]

Hi hope someone could help me out rear demister hasent worked since had the car and I've read on here that you take the big fuse out in boot and put in one above so I did that and it works but next day battery was dead so changed fuse back and was fine

Anyone had this problem or know anything???

Do you have any 'check safeguard' messages?

[shaun_richmond]

No haven't got the trip computer screen in middle but I have inSP come up when I start car up where mileage is but that's not been doing that long

If you have access to a multi-meter i'd check the heater circuit. The spade connector had fallen off one side of the heater element on my old vec. It was as simple as removing the boot cowling and popping it back on. Hopefully yours will be such an easy fix. Can you hear a relay clicking when you press the button?

Yer it did click wen changed the fuse over. Where is the heater element?

[BigWilko]

it's the actual lines on the back window. Remove the covers at either side, pull one of the spade connectors off (if one's not already off) and check for continuity.

Oh yes I've done that and the elements do work but that was only wen the fuse was moved up and then when I turned engine off there is still feed going thru that fuse
