Wiper Delay Non-Functional

I finally, after 5 years of owning this car replaced the wiper switch.(I try not to drive it in the rain/snow) The previous owner wired up a toggle for the wipers.

I currently find that all the wiper functions except delay and single wipe work fine. I have to hold the wiper switch to make it single wipe or it just parks itself.

My first guess is the pulse module, but I can find no replacement parts for that based on a brief search.

Any advice on getting these working?

Probably one of the electrolytic capacitors went bad:

Not the same exact issue but shows how to tell if one failed.

Perfect thanks! I'll be taking a look at it this weekend I think.
