Actual measurements from working/dead units would help, not so much the speculation.


Any final report?

The diagnostic/removal/repair/re-install manual for the 2012 can be found - HA and HAC manuals:
https://ownersmanuals2.com/make/nissan/leaf-2012-372

Take-away is that there are a number of possible problems not all related to the PTC heater itself.

Final question - I need a PTC unit (2011/2012) that does NOT have to be working - did you end up with one that you can sell me? If so, please PM me.
2012 Leaf SL; 34,000 miles. 12 bars - Battery replaced November 1st, 2016.
4000 watts Grid-tied solar. 3000 watts (level II) off-grid solar Leaf charging capable.

Since the car was previously owned, ya never know. If the search was a little better here I might have found some of those threads. Sometimes there was a switch, and some schemes involved pushing the right combination of climate control buttons.


Here is the link to that ingenious solution(s) to the PTC heater Illogic;
