Got a 2008 BMW 320D in for heated rear window not working. New relay was £13 so tried one- still no different.

The fuse which powers the heated rear window is not working neither is the headlamp washer fuse above it.

If i power up the fuse the heated rear window works.

Now i have read that battery voltage is critical on these but if this cut out the heated rear window operation would it cut power to the fuse?

Disconnected the IBS and the heated rear window is now operational.

Battery tests as good so will replace IBS.
