wiper delay setup

[wobblefoot]

I have a 69 f100,Ive gotton the wiper delay I hooked it up per the directions and I only have wipers on one setting,pump works too.I know I did it right because I put one in my 71 with no problem.any help.wondering if the switch could be bad?

i had one do that i changed switches and that didnt help. i used a different box with both switches and it worked. so it must have been a bad box.
