Guys.. I have a 78 Blazer with a bad wiper intermittent module. i’ve looked everyehere and it seems noone knows what Im talking about. They only make this one and no info on subsequent years.
Any ideas???

Wiper module

I’m no expert but I seem to recall some time back a lawsuit with intermittent wiper control...patent infringement stuff and Gm was involved. If the wipers themselves work and this is not about a restoration project should be able to use an aftermarket interface to run the delay. Typing aftermarket delay wiper control brings a list of options on a search engine.
