Hi, please find the link enclosed to the photos of the fully built wiper kit which dosn’t work, as i explained in the last message. Thanks
Sorry, pics don’t allow us to spot a problem.
Assembly and soldering looks OK at first sight.
NE555 might be defective. Try replacing it.
If necessary, please return kit for inspection.
