I have a 5 door Vauxhall Astra [Club Twinport] (07 plate). The rear jet washer is blocked some how. The front jets work nicely (although one was initially blocked but the fine needle tip worked well) and the jet motor works perfectly.
My question is how can I get access to the rear jet washer as it's not really documented. The jet washer is located within the upper rear breaking light bar.
Please see the following pictures;

Any help would be grateful received. Quite the DIY-car newbie!
