Help! This is a safety issue up here I. The Pacific Northwest. Has anyone else had this problem? What’s a fix:
1. I don’t know if it’s software or hardware but we have a 2018 M3P. With FSD 2023.27.7. Never had any wiper problems before.
2. Last week it started really raining. And pulling out I hit the wiper button and the wipers both just open into the extended position and stopped.
3. Even if I hit wash they would stay there and spray fluid. I could move them manually. Down and they would still spray. So the motor was not powered at all.
4. I then noticed that when I moved them up and down eventually it would start wiping again. I tried the two finger reset no good. But somehow after a few times it would start wiping again. Note it was totally stuck. In all wiper modes and in service wiper mode.
5. Another poster mentioned auto wipe is no longer required. And this is true in this car. I don’t know if that’s related.
We then called Tesla service and the next day was nice and sunny and all miraculously worked perfectly fine. He did a hard reset just in case. Checked the motor and it was fine.
So we went off on a three hour drive to Portland:
1. The auto wipers didn’t work at all (I’m wondering is this a front camera malfunction?) during the trip
2. We manually wiped and made it down. And it worked fine for three hours. So doesn’t dell like a bad connection. The rain was zero visibility for hours.
3. Parked the car and had dinner. Then on the way to the supercharger in heavy rain. Same symptom. The wipers extended when I set it to intermittent and then froze up.
4. Tried to manually move them. No motor resistance at all. Like the car thought the motor was in service mode or something.
5. I manually moved them down and nothing happened. Activating wiper service did nothing.
6. Did this a few more times and suddenly it all began to work again.
7. Rain stopped and all was good.
8. Then backing the car out again the at or next stop and the wipers stopped up again. Depowered at the top of their stroke.
Any theories?
1. I guess I could replace the motor assembly. I have an appointment in 48 hours. I’m very willing to do that if necessary
2. Could I guess be a loose connection in the wiper motor as the motor just seems shutoff and unpowered when it stops. Maybe because it’s wet but it seemed to work fine on a long trip.
3. Doesn’t seem like the fuse as it keeps coming back on.
4. I would suspect the firmware but a failure like this with Loss of all wiper function in all modes seems like it would result in massive chatter in this forum :-$
Help! Advice?
