Trying to figure out a weird one.
1 _ wiper Switch in down position (should be off) Wipers operate in intermittent mode
2 - wiper switch up in any of the other positions (assume should be low and high) they do nothing
So the relay is engaging intermittent when they should be "Off" and when they should be going at speed in the upper positions i get nothing.
Could it be a bad switch on the steering column? Or could it potentially be an incorrect switch? I know the intermittent relay was an option at one point.
Any help is appreciated.
Thanks
Did this happen all of a sudden? Has the wiper motor been out of the car lately?
If this happened all of a sudden I would do a visual check of the wires at the motor for a loose connection or rodent damage.
Then I would pull and look at the switch for issues (burnt contacts, melted plastic)
All the way down is intermittent wipers. Next click up is off. 3rd click up is low speed. Last click is high speed. Let us know what year the car is. 72-74 HAS to have a tight ground spring (z shaped copper strap) in the right hand corner, of the steering column.
I just bought the car a few months ago so it has been that way since i got it. The PO did some welding up front and removed all of the fresh air blower stuff so i dont know if the motor has been out. I did find a broken wire headed to the relay which i repaired - rest of the wires look good
I am just trying to fix it before i replace the fresh air box, etc...for obvious reasons regarding access...
I get voltage on the blue / black wire at the motor when the wipers fire on intermittent
what was odd was i didnt get any voltage when testing the red wire(s) on the motor...seems counterintuitive - i would think i wold see voltage there
I have the switch out of the car now so will look at it for what you mentioned
if the intermittent works, probably the switch or wiring is hooked up incorrectly
75 takes a different type of wiper switch. Has smaller base.
Intermittent relay location is on the drivers side front cowl support. Make sure the harness for the relay socket is plugged in correctly at the wiper motor.
NLA switch for a long time. 75 VW Rabbit will interchange. They are rare also. I backdated my column to a 74 and used the 75 ignition switch. Easy swap.
If the fresh air system was pulled more than likely the wiper motor was disconnected when/ if they pulled the wiring back to get it out of the way.
Check to make sure the wires are in the right place

New fuel tank cheaper delivered than any I've found in the US without shipping.
Finally got it all sorted - never got to the final reason the intermittent would stay on when in off position. I don’t care about intermittent so....
I capped off the green and blue/black coming from relay.
Then took the green from wire harness to green on the motor
I now have
OFF in lower positions
And low and high in the upper.
Didn’t have to buy anything
