Multiple electrical problem.

[Alec B]

Hello to all, I have had some new things occur since my recent posts regarding electrical problems. First off all the faults are at the rear. No1 Rear Demister only works on top bar, No2 Rear wiper doesn't work, No3 the rear suspension adjuster doesn't work, No4 the boot release doesn't always work (I'd say temperamental). I have found now that every time the boot is shut the wiper moves about 1 inch until it has done it's full cycle, then it won't do it until you activate the rear wiper. Since owning the car I have fitted a towbar with single electrics, could this be of any significance. Also all these problems occurred after the suspension pump had failed and been replaced, coincidence? Could this be an earth fault or something more? Any help for a weary C5 owner much appreciated.
