Hi 

The glass brake sensor is a very thin copper track which runs round the tailgate window there are two terminals at the bottom of the window one of them has probably corroded off so just take the other off strip back the wire and join together. This will fix the alarm fault 🙂

Hi i found the 2 wires bottom of the tailgate window cut them and joined the wires together and i thought i had fixed the problem until the next evening then the alarm went off again , it seems to go off at about 7pm when the back of the car is in full sun , anything else i can try many thanks graham
