I bought my wife a 2014 Toyota Corolla LE Eco a little over a year ago. Right as prices started to sky rocket. Paid 6,000 cash has 120,000 miles car runs beautiful and gets incredibly gas mileage. Strangest thing happened the other day may 4th 2022. We live in heart of Mississippi and this time of year these giant bugs like to kamikaze them selfs on the windshield doing so she tried to clean it off with wind shield wipers and she held it down for bout 5 seconds for it to spray enough fluid to get the bug off the wind shield. Then fall of the sudden they wouldn’t turn off. So she starts to panic then the little red security button on the left of the steering wheel started to flash and horn and going off kinda like the alarm was going off wile she is driving. She stoped turned off and it cranked right up wipers going then about 10 seconds latter the horn starts going off like it’s being stolen. What on earth can cause that to happen? I’ve yet to find anything on the web with similar experiences thank you Scotty
We’ll here’s the update. After hooking the scan tool to the obd port it pulled no codes (expect tire sensor witch is dead in one of tires) under the driver side panel I pulled the wiper fuse 15amp and it was blown. Replace it with proper fuse and the problems subsided. The immobilizer secretary light wasn’t flashing wipers worked at all proper speeds..
Untill….
She pulled windshield wiper switch (stalk, handle, arm, lever or thingamjig what ever you call it) towards her to spray fluid on the windshield. Then back to square one. Did the same thing. Blown the fuse wipers wouldn’t turn off and theif system started to act up again. So as for now we just replaced the fuse and hope she dosent randomly try to use the sprayer (plus keep extra fuses in the spare compartment) so as for now I’m pretty sure there is a short in the multifunction switch wiring who knows looks a issue I’ll be addressing soon. Any other ideas, suggestions or criticism are welcome.
Y’all come back now ‘ya hear!

No, they were minding their own business. You crashed into them. 😛
@mmj I’m pretty sure your issue is the Clockspring in your steering wheel given the issues you’ve mentioned.
Was the security light on when this happened? If so, if you have another key, try that.
Yes sir I do that. What kinda made it stop was I took the ground off the battery and put it back on and the blinking light stopped untill she turned her car off and crank it again. I plan on taking the ground off for a little longer and turning her headlights on so all the juice will be out the computer I hope that helps. It came a bad storm last night and didn’t get a chance to try that. I took the fuse out the wipers to get it to stop I don’t understand why they won’t quit maybe the switch is shorted or something
Check the fuse boxes and make sure they are dry as well. You may have faulty relay and/or fuse for the wiper blades.
I sure will I’m gonna hook a obd2 scan tool to and see if it can pin point anything I’ll post the results I find the fuse looked slightly blued but wasn’t burned out seemed to me like something is shorting out I’m just a welder I wish I would have leaned more about car mechanics
Your car has continuously variable valve lift, continuously variable timing, probably continuously variable transmission - for some reason the wipers and the alarm are also continuously variable.
Do you know if this car might be been flood damaged?
Go to an electrician, I think something is very wrong in your cars wiring.
If you want to do it DIY, get an all systems scanner and schematics - and I’d try figuring out if the module that’s responsible for the wipers (I think it’s the BCM?) is getting the correct signal.
If it’s getting the off signal on its pins, and yet it’s commanding the wipers to be on - I’d assume it’s a bad bcm.
Is the alarm factory? What are the criteria to make it go off? If there’s a “disable” signal going to the module, does it arrive at the pin? Is the source of the signal alive?
Maybe you just have a distorted CAN signal? Then it’s scoping it and trying to figure out what’s causing it.
