i have a 93.when i got it the washers didnt work and the wipers didnt work on interval.i put in a used motor and now had washers and the interval wipers ran steady when on.a few days later the whole thing quit.put in a new motor now my intervals work in jerks.go a few inches and stop.sometimes not at all.im at my wits end with this thing.

Sometimes the wiper module can cause problems but usually only one and not multiples like you're having. Are those new motors or from a wrecking yard?

Here's a diagram for the system. Check diagram #17 | Repair Guides | Wiring Diagrams | Wiring Diagrams | AutoZone.com

Dont know the set up on that car , but usually on other cars with the same fault it was caused by the "parking" mechanism / contacts inside the motor that was knacked
