Everything must be closed for the wipers to function.

Sounds very odd but it could be the front SAM has failed?

Thanks for reply .. it is odd ..ive disconnected the battery to see if it will reset the ECU was working fine until i got out of car with them on .

I am not sure if your car has door pin switches? It may be worth checking the interior lights come on and off with the doors opening and closing. If the ECU thinks a door is open it will halt the wipers.

Thanks again yes it has door pins .. which work on the windows going up down few mill as it should but the interior light is doing nothing and the door lights nothing ...... it used to come on when you opened door and slowly fade out on closer ... does work on the console so power getting to them .

Okay. So it sounds like the issue that the door pins are not telling the ECU that the door is closed. Have you got any electrical switch cleaner? A squirt of that into each pin may do the trick. You can try and pull the pins out from the door frame. Be careful here, it is easy to lose the wires back behind the hole when you do this (in some cars) A piece of string or a tie wrap can be handy to put through the wiring while you work.

Now you may have a dead door pin that needs replacing? That should be checked by simply opening closing each door to check which ones operate the interior lights and which one does not? A new door pin may not be that expensive if you wanted to bypass the cleaning route?

The door pins seem to be working on the windows press them in and out and windows react lights on bottom of doors not coming on at all or centre light . . Would a squirt of WD40 behind switches work as a cleaner ?

WD40 can cause more harm than good as it will attract dust at a later date. I would really try and get some switch cleaner from Maplins or the like?

But... If the PIns are operating the windows but NOT the lights I am getting confused as that suggests that there is something else in the circuit that disables the lights and wipers. We could be bac looking at the Front SAM again. That would require STAR to be connected.

I remain uncomfortable that this all started when you opened a door. That suggests that the door or the door pin is the trigger.

Anybody else?

Wild suggestion! The Bonnet Closed Switch is not being depressed enough to allow the Wipers to activate and sweep, the Wipers were working. but the Washer was not. you opened the Bonnet to reattach the Wiper Nozzle. closed the Bonnet and the Wipers won't work!

Hi Abs are you stalking me by any chance?

I have exactly the same fault on my car, although not as desperate as your situation..

Not saying you have the same fault but it may be this:

In the link above the chap had multiple electronic problems, when he unplugged all the front SAM connections he noticed some corrosion, after plugging all the SAM connections back in, everything started working again..


If both doors pins aren't triggering whatever is supposed to work when either door is open then Bruce's SAM suggestion may be worth checking out, you seem to have more than one fault.

I know its very confusing i will try and explain again .
I was checking everything for the mot .. Sat inside car tried wipers fine .. pulled bonnet catch and got out and noticed wipers had stopped midway . Stupidly i forced them back down again .... replaced the washer pipe that had come loose and filled water bottle ... got back in car with bonnet still up washers or wipers not working .. put bonnet down washers ok but no wipers . .. i never knew about the everything needs to be closed rule .
The door pins work fine on windows but no interior light or door lights come on but did before ... sorry for being such a pain .
