My van is a RHD, and yes exactly it looks like a small maybe 12 inch extension. I did not expect it, but I’m glad I didn’t start looking for nonexistent electrical issues behind the dash…
aw man, thanks for this tip. I even ordered a new driver window motor mechanism and turns out it was that loose harness plug under the dash. reseated it and then added a zip tie to it for safety and now my windows work reliably again!
