89 S10 wiper motor troubleshooting help

Here's my problem, the wiper's quit so went through a checklist. I checked the fuse, good. Checked the power supply on the harness that's plug's into the motor, getting power in all setting's which are only slow and fast on the wiper switch. Assuming that it was the motor itself, replaced it with a salvage yard special but still no go?. Now thinking the one from the yard is bad also but looking for some feedback from the knowledgable member's here. Any help would be great since the wet season is coming fast. Thanks E.

Is it the delay wipers or reg.
Are wipers dead on all speeds?
Have you tested wiper switch and fuse and ground and power to wiper motor?

There was a recall on this issue. Some Chevy models had bad circuit boards. They could be re-soldered or replaced. I think a search on this forum should bring up something. Seems to me that the controller located on or near the motor had a cover that had 1 or 2 screws and the circuit board had a screw in it too. very simple to R&R

Thanks for the responses Gentlemen and after several days of going through the system found a bad ground where the moter mounts. Thanks again for you replies. E
