Hi all,
On a cold and frosty morning etc etc
I notice that only the lower 4 or 5 heating strips across the rear window glass of my Omega estate seem to be working.
Have not had much chance to delve into it yet, but wondered if anyone has investigated similar problem. Where do you get to glass heater strip connections to investigate. Are all the heater strips in parrallel, or some in a series connection arrangement ??
I remember seeng a thread long ago, about the heated strips are also the radio aerial.
Any info welcome.

If you've got missing horizontal heating bars from your screen, it's because they're damaged. As yours is an estate - ex police too - the screen will be likely to have beeen damaged by closing the tailgate onto things in the back, and I think I'm right in saying that your radio aerial is on the roof rather than in the heated rear screen like on a saloon.
Years ago you used to be able to buy a tiny little bottle of conductive paint to repair the elements, i haven't seen it for a while ... but I haven't looked.
You're lucky in that you have a few bars missing, my Astra estae has about 3 that work.

Sorry for the hijack but if the radio aerial is in the rear window heater then what is the aerial on top of the car for?

got the same problem with my rear window, got to go through with a test meter to find the breaks then hopefully solder it or get the conductive paint [easier than soldering], mines got the radio aerial in it so dont know if any lines are not supposed to heat up ;)

saloons have aerial in rear window, estates have traditional roof aerial. If you saloon has a little stubby aerial, thats a cellular aerial for your built in phone or phone prewiring

.. which can easly be changed for something more useful, as I discovered last weekend...

Ditto, thinking about replacing mine with a DAB aerial.
What are the issues with removing the roof lining? :(

Firstly, the mobile phone antenna simply unscrews from the antenna base and you might find you can thread an antenna to screw straight in. The rf cable runs down the driver's side rear pillar, under the rear seat elbow cushion and along the driver's side sill under the plastic trim panels. It terminates at a connector (a wierd one) behind the driver's side kick panel.
If you need to replace the whole thing as I did, no need to remove the roof lining. I found just the plastic trim strip that conceals the high level brake light is enough. With care, you can snap the centre of this strip downwards away from its mounting clips and carefully ease one side out from under the rear pillar trim panel. You will then be able to see the rear of the antenna base.
The antenna base simply unscrews from the top, leaving a base section connected to the cable underneath. It has an FME connector, IIRC, female on the cable and male on the antenna base.
You will be left with a hole perhaps 15-18mm diameter in the roof panel. I wanted an antenna to cover the 2m and 70cm amateur bands but without looking as obvious as most amateur stuff does. I used a Panorama M8 base http://www.panorama.co.uk/uk/products/pmr_modular_bases.html. Looking at it again, their "euro mount" base looks to be very similar below the panel to the base I removed and would probably screw straight on.
I used the existing antenna feeder to pull a new length of coax across the roof and down the pillar from the antenna to the rear seat belt area and ran it into the cubby hole in the boot where the radio is mounted.
The antenna I used is an AVDFHB http://www.panorama.co.uk/uk/products/pmr_modular_whips.html but you can get a whole range of antennae for various different frequencies depending on your interest. They can be removed with just a single grub screw so you could even have a couple and interchange them to suit.
