if any of you have a AC and heater issue,
ie, will not blow hot or cold and no power is pulled by the heater or A/C compressor then read on....

Scan for DTC's with your 'LEAF SPY PRO' and get this as a result?..



do you have a manual Heather mod for your Leaf (as seen in http://www.mynissanleaf.com/viewtopic.php?f=37&t=20446)? Try removing it, putting the cabling back to original, and resetting the DTC's codes.

AC back up? yay! if not, (SAD FACE) not sure what it is.

anyway, hope this helps.

I had this issue and figured it out, which I have to as my 2012 is no longer under warranty and the dealership is one of my last options.
