I bought a used 2011 leaf a couple years ago, and everything was operational at that time. Then one day I discovered the AC wasn't working anymore, and doing some testing also discovered the heating wasn't working anymore.
I took it to a dealer, and they claimed something had shorted and blew a fuse in the dc-dc converter, and they'd need to replace the heater, compressor, and dc-dc converter.
After doing some digging, it seems like the heater and AC are on separate fuses, so it seems odd that one short would impact both. Anyone have any ideas/insights?
The DTC codes that are coming up are:
>B2788 0009 HVAC Comp Over Current HAC-99
>B2770 0009 HVAC PTC Heater Circuit HAC-75
