2007 Vauxhall Vectra lights tailgate

Hello .. thanks for the donation .. much appreciated You need to check the wiring to the rear of the car sounds like you may have a damaged wiring loom from front to rear of car .. I do not have a wiring diagram for this vehicle as it was not released in the USA .. you could try the vauxhall vectra owners club website to look for possible smiliar faults and remedies VVOC.COM hope this helps.
