need to get my window replaced again, 2nd time in two months, but is it possible to wire a heated one up as the one in it isnt heated

I know the connectors are there at the bottom of the screen in the middle in engine bay but what else do i need apart from teh swtich inside?
Anyone know?

thanks

 

possibly a relay with timer and a fuse - best checking other cars like yours that have the heated screen

 

Cheers, if im getting the windscreen tommorrow and the wires are there it shouldnt be a major problem to getg it working should it? Just dont want to get it them not be able to use it

 

entirely unsure - never mesed about with mine as it works
