..well I think I will start a new thread about my setup..basically I wired everything as “per factory” everythings seems working but having a big issue actually..in the switch off position the wipers still work intermittently..seems like I lost the fastest settling aswell (although not sure about that as battery may be weak)..anyway I’m trying to figure out what is going on but I must admit my knowledge of electrics is close to zero..there’s some threads about it on the samba I spent hours on reading them and it seems the factory wired it differently to what is in wiring diagram..really confused now..will try and put up some pics later tonight though (stolen from the samba) and some of mine Wysłane z iPad za pomocą Tapatalk
Has your stalk switch actually got all the connections shown in that diagram, particularly “S1”? How many stalk positions have you got? 3 or 4? Or even 5? (Does actually seem like it’s working - it wouldn't be able to do what you show in the vid if it was wired incorrectly).
I expect you have somehow swapped a couple of wires from the wiper switch. Your park power looks like its swapped with the intermittent relay connection. This might also explain the fast position not working .. in my messing with the 99 relay I managed to get the slow speed motor power wire connected to ground via the parking switch on the motor gearbox while trying to run the motor via the fast switch .. so it ran fast for a while until it parked, then tried to short out the battery via the motor armature between the fast and slow speed connections.
..yes it has s1 and all the connections ..I’ve got one extra stalk position (pull it down to switch to interval wipers) ..well that’s where I get confused..it seems working but the problem is I can’t turn the wipers off now as they work intermittently when I pull the stalk down (correctly) and in the switch off position..so practically they wipe every 6 seconds all the time when the ignition is on...

..yes I think I did..if you look at the pics I stolen from thesamba theres a “mistery black/yellow wire” in the og loom (for buses with the intermittent wiper relay) that certainly goes down to the relay but on the og diagram it’s wires straight to the wiper motor..there’s confusion about it.. ..mhm am I something missing here?..deffo black/yellow wire connected to the relay (it goes from the motor I suppose)..so what’s happening with the black one from the motor and the black/yellow from the switch?.. ..and my stalk with wires coming out of it..

..just to add..it doesn’t make any sense to me..I did look at all og wiring diagrams (they all the same btw) and the only difference between a intermittent wipers one and a none int one is that black wire going either straight from the switch to the motor or on int option from the switch to the 53s on the relay and from 53m to the wiper motor plus that brown s1 for the wash/wipe option I think, but this pic shows clearly something completely different (can’t find it on any wiring diagram) ..double brown wires and a couple of black/yellow coming from the wiper motor?? ..honestly a mystery for my non electric brain Sent from my iPhone using Tapatalk
I’ll have a think later when my brain’s working properly. Did your van have intermittent from the factory or are you adding it? As above, if intermittent’s working as in the vid and the wipers aren’t blowing the fuse, does imply it’s connected more or less ok (apsrt from not turning off?).
..Im adding it but the switch has factory itermittent option on it (all the wiring) it came from an old 1303 that had it from factory..so yes it is exactly like you say it all works properly apart from the fact I cant switch it off now..anyways heres what I quickly figured out just from looking at the pics of the loom and plug stolen from thesamba.. Does it make any sense to you (pls bear in mind Im so rubish at electrics you wouldnt believe..well you will now) ..does it make any sense compering to this .

Pin S needs to be disconnected from 12 volts when the wiper switch is in park position.. if it goes to 12 volts, the relay starts pulsing connecting 12 volts periodically to the 53m wire making it run periodic single wipe and park cycles. Same as pulling back on the wipe switch..
..don’t know tbh..I assumed that if both features work (wash/wipe and intermittent wipers) it is ok and the problem is rather in connections but..noidea howto check it? Wysłane z iPad za pomocą Tapatalk
..ok Mike but how would you suggest me to connect it then?..I’m little bit worried if I connect it wrongly I might burn something in the relay and they quite hard to come by..also I thought that the black wire 53 needs to go through the relay to trigger intermittent wipers?..and the S is the wash/wipe feature?..hmm sorry but I’m really hopeless if it comes to relays...

..hah now I’m thinking my relay came off porsche 924 butthis is the factory one..they may be slightly different and that might be my problem? Wysłane z iPad za pomocą Tapatalk
You can hear the relay clicking in intermittent wipe mode in your video when the wipers should be parked. The intermittent relay should be sitting with 53m connected to 53s when the wipers are running constantly, and when the wipers are meant to be parked. If you run the screen wash for a long time, do the wipers run intermittently or constantly?
..if I run the screen wash for longer the wipers run intermittently..and more interestingly it does not matter if the switch is bolted to the column (earthed) or not..everything works still no park position Sent from my iPhone using Tapatalk
..Mike when I ground the S pin on relay intermittent wipers stop working..they run in slow mode and very slow in fast one.. Sent from my iPhone using Tapatalk
..now didnt do anything to the connections and wipers run all the time constantly in off position..funnily enough with the switch off the column and completly disconnected..this is s sign to give it up.. I will put it all back as it was atleast I could still use my bus..thanks anyway Sent from my iPhone using Tapatalk
