Q: Time delay of wiper not functioning on 1996 Nissan Sentra

Earlier I posted a question about Wiper Motor Issue and I got a response - Thank you.
Unfortunately suggested diagnosis has not lead me to a conclussion of identifying the failed component. I have tested both the brown and blac ground wires and they both react correctly. But the problem of the intermitent (time delay) wiper function still does not work. Also, when wiper does work in low and high state it does not park in the steady state down position when turning off the wiper switch. The blades immediately stop right in the middle of a wiping swing on the wildshield.

So my question is ...

#1. Is this a problem characteristic of a failed wiper motor amplifier?

OR #. Is this problem caused by the motor?

#3. where is the wiper amplifier located? inside and under my dash, inside the wiper motor assembly, or part of the wiper switch assembly on the steering colume?

Thank you for your expertise advise and support.

if your car has variable wiper speeds, then yes this sounds like a bad amplifier. However, the really best way is to check the switch as well. I would go to and pay for a 1 yr subscription for your vehicle's tech info, that way you can have access to all the diagnostic tests AND proper component location info, so you won't be guessing. That is what a tech does/ should do in a shop i.e. do a thorough inspection of the system with the factory diagnostics. Then you will KNOW.
