Okay I did an S15 conversion on my S14 and I have swapped all electrical to S15 wiring and I have also swapped the S15 Wiper motor. Problem now is that when I refit the wiper arms and blades and I switch the wiper on they for an instant rotate downward onto the cowl panel and then go up, not all the way but most of the way and reset to the proper height. Then next time they momentarily go down again onto the cowl panel and do the same sequence. Are the S14 and S15 wiper linkages the same length and is everythign interchangeable between both setups? Only thing that was not swapped over is the linkages and the actuall wipers spline setup. Need this solved ASAP, any help is appreciated.
