K2599 wiper kit

Hello - having just completed my K2599 wiper delay kit and found a problem, I searched this forum for a solution to my problem, I find it is the same as a previous correspodent, Pitchelu Gerrard, on April 14 2008. His kit would only work on the five second delay, the final position of the switch. In the other positions it will only work for one wipe and the light stays on after that has completed.
I note he sent his kit back and it was repaired. Is the problem one I can resolve without having to post it to Belgium?
Thank you.

Sorry, there are no known problems with this kit, which has been on the market over 20 years now, unchanged.
Most likely an assembly problem.
Sorry, this forum does not allow picture uploads
If you can provide LINKS (e.g. by using a free online picture base) to HI-RES and SHARP pics of your assembly (both solder- and component side)
then we can take a look and provide some feedback.
