Just in case anyone's interested.... today on this nice sunny afternoon David decided to "have a go" at fixing the wiring in the tailgate for the rear wiper / demister / rear interior light (boot light).
What he did waz... removed the grommet from the top of the right hand side of the door housing, moved out of the way, pulled out as much cable as he could, including the connectors, he found 6 broken wires that he then rejoined using spare wire and chocolate boxes. A bit fiddly, but managed and now Hey Presto ! all working again now. Having got the info off this forum as to what fuses were involved he'd checked them and knew it had to be the wiring as they were intact.
So thanks PEEPS you did it again...
NEXT WEEK HE WILL BE MOSTLY TRYING TO FIT A TALKING CAR ALARM just aswell its not adaptive it will probably hear a few colourful words.... its sposed to be fitted to a COIL !!!!! but starter motor will have to do .....
