Any guidance please, 2008 C5 X7, 2.0 HDI Estate. Wipers have been mis behaving for a while. Firstly stuck on intermediate on whichever setting then they folded over each other and left stopped working with right jerking up about 4" then back down again. I've read that it's probably the ECU in the slave, left side. I have removed the motors and panel to get to the ecu and put the multi meter across each terminal pin and the connection to the PCB and there seemed to be lack on continuity. Tried to remove the PCB but to no avail, rechecked continuity and it seemed okay after messing about but when i refitted the motors they still don't work. Are new motors required as the few there are about seem expensive and i may need two. Or is it worth trying to get them looked at by an auto electrician. Does anybody have any experience with this.....PLease Andy
