Sorry if this has been asked before.
Our 2015 base model Leaf with 52K miles is not putting out any cold air from the cabin vents. I thought I would try using a recharge kit with R134+ that includes sealant before taking the vehicle to the dealer.
I've watched several YouTube videos, and the procedure seems doable (famous last words?). However, I thought I would first check on this forum to see if the procedure is different, since there isn't an engine running that is turning the compressor.
2015 Leaf S. Bought 2 year lease turn-in with 14,500 miles. Drive about 14k miles/year. Most charging from 'free juice' at nearby ChargePoint or Nissan or other free L2 public chargers within walking distance. ICE is rarely driven pickup truck.
