Hello just getting ready to have the van back in the road after 5 years of work . The only thing is I have I very late baywindow 79 and I can't seem to find a diagram of the wiper motor wiring . Has anyone got a pic of this in the dash I just need to know where the wire go . Any help would be good Thanks Simon
There shouldn’t be any wiper wiring in the dash on a ’79; there’s a column switch with a plug for the motor. And if you have the intermittent wiper option there’s a relay too but still nothing on the dash. ’79 wiring diagram here: https://www.thesamba.com/vw/archives/info/wiring/baybus_79_color.jpg
What's the issue. Sometimes earlier motors get fitted when the original breaks. I've got wire colour conversions if that's what you need.
Thanks mark it sounds like it's been changed I'm at the van tomorrow so will find out the wires . I think there is no plug but can't be sure will up date tomorrow evening thanks for the help Simon
Ok been and looked at the wiring and it looks as if someone has replaced the motor and all wires are the same colour. Also there is a cross shape connection so all the wires have spade connectors on . Please tell me if someone can help it has my head in hands Thanks simon
That will be for the slower wiper speed setting....it will take longer for the electricity to get there. Obvious really.
This may help https://www.thesamba.com/vw/archives/info/wiring/baybus_7374.jpg and if you are pulling the whole assembly apart don't follow the Bentley manual it's wrong as others on here will corroborate
I'm not looking to pull apart . I'm look at getting these to work so the question is can anyone help with what goes where
Would be helpful to have clear pics of the existing wiring from the dash look, and the wiring coming from the wiper motor itself.
What is confusing about wiper motors is that the wiring is arranged so that there are two power connections to the motor, one for fast and one slow. One uses brushes at 180 degrees to each other, the other speed uses 120 degrees between the brushes.electrics says the 120 degree one is fast as the motor has to spin faster to make its back EMF match the battery. On mine it sometimes seems the other way round as fast develops less torque ... The switch wires 12 volts to either the fast or the slow motor connection. In off position it connects the rotating switch in the motor assembly to drive the wipers fast for a final cycle and then when they reach park the rotating switch shorts the motor to brake it hard. Wipers that are not parked but with the switch in any position wil be permanently powered and the motor will cook.. Look at the Current Path diagram as that is clearer than the earlier schematics.
Thanks for the diagram . Was going to ask if anyone has a picture of the wires that come from the wiper motor . All mine are one colour of I can get a picture of what colour the wires are supposed to be Thanks for all the help Simon
Hi,I think I have a wiring loom to the motor if that helps you ? .I will look for it tomorrow but if I remember correctly it goes from the switch and has a plug to the motor .
