...It shuts off when i unplug the wiper switch and when i plug it back in they operate again.  Even plugging the switch up without the module same thing....
Did a lil bit more diagnosing and found without the module connected everything works fine....

What changed since yesterday?  Are you certain there isn't compromised wiring between the delay module and the wiper motor that shorts or grounds intermittently as the harness is moved around?  Make sure there isn't any conductive "debris" between the terminals of the harness connectors.

In other words... if people learn by making mistakes, by now I should know just about everything!!!

If all of the external wiring is healthy and correct, and the problem occurs ONLY with the delay module installed, replace the delay module.

Are you saying the gray wire was still disconnected from the motor when you removed the module from the circuit?

Perhaps, reading through Wipers won't turn off 1985 will help you get a handle on the problem.  The basic system between the model years is the same.

Thanks bd. Found the problem it was the delay module. When i plug it in it grounds the low circuit for some odd reason. But if i plug just the switch in everything operates as is should. Just dnt have pulse as if right now :'( a new on i 173 dollars so i will be saving up for one. Thanks  again bd for all your help
