Here's the thing. My 2018 initially had no issues with my auto rain sensing wipers. They were normal. If it rained, they turned on automatically.
Wipers.. WTH? Thought we were talking about door locks. Stick with me...
I left my wipers on auto all the time. When it rained they came on. If it didn't rain, they don't come on. It was great for a few months.
At some point I had my door locks changed from ignition to shifting from P.
Then one day it started. 1/20 times when it would start the wipers go crazy and run non stop. This is only if I left it on auto when the vehicle started up. Flipping the stalk to off stops it, but putting it back on auto or leaving it on auto would keep the wipers flipping out. The only thing that can be done is to power cycle the truck.
Nissan couldn't figure it out so they replaced the control module for the wipers and the BCM (body control module) that runs the wipers, seat memory, radio, courtesy lightning, intelligent key response, etc.
The BCM also controls the door lock and unlock programming. They had to reprogram both of my keys back to the new BCM. They forgot to reprogram my door locks back to shift only.
But my dealer is 30 miles away so I said forget it.. I would take care of it the during the next oil change.
I'm the mean time, with the new BCM, my auto wipers hadn't kicked back on for 5k miles.
Today I got an oil change and rotation, and while I was there I told them that they forgot to change my door lock from ignition response to shifting response, so they did.
And then it happened. The very next start up with the wipers in auto they went crazy and wouldn't stop.
So here's my theory....
Changing the door lock/unlock programming in the BCM is screwing with the programming of the auto wiper function in the BCM.
Thats the only explanation. And the 2018 and up has a completely different BCM than the 2017 and below.
So is there anyone that has had thier door locks changed from the ignition function to the lock/unlock when shifting from AND has also had thier auto rain sensing wipers flip out and come on and run non stop?
