I have a leaf (115K miles) and recently the wipers failed inconsistently - of course they working fine when I took them to a mechanic and he inspected everything and we could not diagnose the problem so he suggested the most common problem in other vehicles was the wiper motor, so we replaced the motor and the transmission,
what the hell
this was good for a week, and then they failed again, except this time it was a permanent failure. When inspecting, wires all look good (those that are easily accessible) battery tested in limits under load. (battery was 12.4v before being tested) the switch on column checked ok. if you put voltage to the wiper motor it works... damn - so it seems it has to be the battery or the charging system, but they test ok near as we can tell.
mechanic had taken battery out to test it and while it was out he hooked charger up where battery resides and
oh my
wipers worked
so he charged the battery some more and installed it and then wipers worked - but then -
I took the care home, it worked that day, but the next day the wipers failed (of course the day it failed again was 4" per day, not unusual here)
so now I am beside myself. I live in SE Alaska so I live out of reach of a dealer (if they would or could figure it out).
but if I were desperate it would be about 2500$ round trip to a dealer, and this is a 10yr old leaf so this does not seem a wise way to spend my money
I suppose it could be the control module, but of course they are expensive and if I were to buy one and I do not even know if that would solve the problem, and I especially do not know if my mechanic would be able to program it as he is not a Nissan certified repairman, and Nissan keeps their cards close to their chest.
I was thinking even though the battery checks out and it is only 2 years old, could the battery somehow cause the problem? (especially if it worked for a short time once it has been charged.) Since I believe the charger provide some higher voltage (what? 14-16v?) in that case it should not be the charger. that means either the battery of the control module. now I am talking myself into believing it might be the control module.
DOES ANYONE HAVE ANY KNOWLEDGE OR EXPERIENCE WITH THIS MALADY?
THANK YOU
