97 Caravan grounding points

Still having the wiper issue on my 97 Grand Caravan. Swapped out both motor & switch, swapped the relays & such. Last step is to check the grounds but not sure where to look.

Under the dash & under the hood?

Thanks

you should see like cooper staple on motor mount with bolt through it that ground all else neutral or positive

Ground points are as follows....Wiper relay ground point G101 located on engine block, Wiper motor ground G300 located on left cowl ground block, Wash switch ground G200 located on instument panel ground block.

Adding some wires between the ground points may help. These vans have trouble with bad ground contacts.
