The 2011 Used Leaf with 20,000 mikes seemed like such a bargain.
After a few months, the heater has given out. The shop just called to say the heater core is bad, and it's a $1240 part plus $1100-$1400 labor.
The dealer gave more or less the same price. The dealer says no service bulletin exists for any sort of discount.
For $2500, I'm willing to do a lot of shivering. I used to ride in an old VW bus that seemed to defy the laws of physics and actually be colder inside the vehicle than outside. The saying in the old days was "A beater with a heater," now the heater is half the price of the entire car?
If it isn't leaking, I could never see any justification for putting $2500 to fix it, even doing the work myself and a $1250 part I'd never do it, let Nissan keep their overpriced heater. You really can't get one from a junkyard either since there is no telling when that one will go out. I'm wondering if mine in my 2011 LEAF works, as I never use it here in Florida.
It seems though that GerryAZ may have something worth trying if you can actually replace the external temperature sensor for a reasonable amount of time and money. Otherwise maybe it is possible to modify it (at your own risk of course) with some wiring and a switch to override the temperature sensor and force the heater to work?
