Thanks. If you're reading brown = live like with domestic plug wiring then I don't think that necessarily applies with car wiring?Presumably from the schematic Pin 1 and 3 are power. Brown wiring and a switch in Pin 1 would indicate that is the positive potential so + battery terminal to Pin 1 and - battery terminal to Pin 3.
No thanks.might be better if you try to offload the car ASAP.
With the ignition off and the wiper cable disconnected and using the multimeter in continuity/ohm meter mode, pins 1 (brown), 3 (black) and earth (via the metal casing of the motor) are all continuous which is part of the reason that I'm confused and I'm not sure that this (below) applies...?Have you an ohm meter ?
If you have check if there is continuity between any 2 connectors.
If there is this should be the motor windings according to your diagram. Connect 12 volts across these 2 connectors. The black wiring is connected together at S47 so I would presume that this is the negative earth.
That's the thing.If you test the car loom connector with a voltmeter you might get a better idea.
I assume the wiper motor is single speed. One wire is probably the parking supply. This should be switched permanently when your ignition is on. There should be a second supply from the wiper switch. These switched supplies could be either + or -.
I already told you that I'm not going to do that so please stop suggesting it.I've owned Renault and Peugot cars from new in the past which afre premium French compareed with Dacia. All had major electrical and mechanicla problems ( The engine actually fell out of a 6 month old Renault) - held in the egine bay by two M8 bolts one which sheared) so I'm a firm believer in "not owning" French cars. Sell, sell while you can still find someone to take it off your hands. Put it down to life experience and lesson learned and nevr buy French again.
Yes.Is your car a hatchback ?
Thanks. I'll see if I can access to check. I'll also see if I can check the relevant output from the BCM (in the passenger footwell) to see if the voltage is present but never makes it to the motor.A weak point is where the cables from the car body connect to the tailgate. The constant bending can cause a break in the cables. This could be a likely cause of your problem. The copper can break inside the plastic insulation. If you can get access to the cables in the rubber gaiter you could pull on them and the broken one will stretch at the break.
Bingo! That's exactly what it was. There's a rubber ducting between the hatchback and the body enclosing the wiring. I prised it off and, sure enough, that's where the problem lies. There was very little slack and the opening and closing of the hatchback must've broken some of the wires. Thankfully this only seems to affect non-essential features and not stuff like the rear lights, indicators etc. I'll have a look at patching them over the next few days and then see if the wiper starts working again. Thanks a million for the nudge in the right direction.Is your car a hatchback ?
