January 11, 201610 yr My wiper started to go a bit wonky in November, a quick wiggle of the tail Gate wiring would get it working, last night it stopped completely, I've pulled the trim off to try and find the break, i assume it's in the tailgate/roof. So far I've managed to trace wiring wise, Window demister Red/blue Back Lock mec Green red Pale green Door release actuator ? Yellow Black Wiper Solid dark green Green/ yellow stripe Blue/black stripe Black Assuming this is right any idea which are power intermittent & on wiring ? For the wiper Initially I thought it was the dark green so tested before the door hinge with multimeter and in the door it's self I was picking up voltage when on before the tail Gate, and none when switched in the off position, but then the wiper stopped working completely so couldn't test any further, A, do I have the right wire for power to the motor ? B, maybe the break is further down the loom ? I wanted to just strip out the faulty wire and replace with a fresh length Any ideas or someone with any knowledge as to the wiring colours would be great
January 11, 201610 yr I would pull rear door card off & inspect right at motor to try see what failing & trace wires/colours without error, try a temporary new earth too .
January 11, 201610 yr Author Well I've found the problem Now it's just a case of trying to strip the old wires out and replace, Does the loom go down to the floor or across the roof ? Looks like at least 3 have perished with age
January 11, 201610 yr Author Thanks for the info Mr b. She is approaching 20, so looks like I'm going to have to cut the rubber boot thing off try and run some new wiring through and solder back together,
January 11, 201610 yr Author Sorted ish ! Managed to up upside down solder a new length of wire into the tailgate, then at the other end, wasn't pretty and the join isn't the best but pushed it down inside the body of the car so it shouldn't get caught, there was no voltage going to the yellow one so I can only assume that it was for the old central locking that's been made redundant with the alarm install
