if there is no hole near the front of the passenger inner wing for the bottle neck to come through then your car may of had the inner wing replaced at some point with a xr3i or rs16i inner wing

the xr3i used a rectangular shaped washer bottle which mounted onto the inner wing in the engine bay

the rs16i used a round shaped washer bottle which mounted onto the inner wing in the engine bay

have you checked between the inner and outer wing to make sure there is no bottle there?

try tracing the piping back from the washer jets and see where it goes too
