Back window desteamer problem!!

[silly_bee]

My back window of my 1998 corsa keeps steaming up and i cant find the button for it! is there a specific button or is it the same one for the windscreen??

You pull the knob that controls the blower fan.

You have an electric demister on your front windscreen on your 1998 Corsa?

[ummmm]

Same one as the front window but pull it

More importantly if it keeps on misting up could it be something more concerning e.g. rainwater seeping into the car through a dodgy seal somewhere.

My old Astra suffered constant misting of the rear window and I had to always have the rear window heater on to demist. Some time later I had to get the spare wheel out of the boot and when I did I found the cavity in which the wheel is stowed was about 2 inches deep in water. It was a slight crack in one of the hinges of the tailgate that allowed rainwater in over a long time, which dripped inside the boot and collected below the spare wheel. The constant moisture on the back window was from the carpet drying out!

I got the hinge rewelded, thoroughly dried out the carpet and wheelwell, and after that no problem with a constantly misted back window.

Might be worth checking.
