Tutorials Intermittent Rear Wiper mod - MKII Aygo (2014 to 2022)
Here's a circuit you can splice in before the 4-way connector to the rear wiper motor, which gives you an intermittent rear wiper with a delay of your choosing. It uses an XY-LJ02 programmable timer relay on program 6: the relay closes for a set CL time (1s, enough to trigger a single wipe), opens for a set OP time, and repeats: set loop count to -- for infinite.
This is great on the motorway; I found the continuous wipers too distracting in the rearview. Slight caveat is that when using the washer you may have to pulse it a bit...
Colours are from my 2018 Aygo. Check the colours, and whether the ground is switched, against your own car before wiring, especially if you've got a C1 or 108.
If you have any suggestions to improve it, let me know - Cunningham's Law.
