A 2009 Maxima blew cold at idle, then warmed intermittently on the highway before cooling again.
What the report actually shows
The source gives the driving condition but no pressure, compressor-command or coolant-temperature readings. Contributors suggested several possibilities, none confirmed by a follow-up.
Reported outcome
The reported cause and final repair remain unknown.
What to take from this case
Record ambient conditions, engine temperature and whether the compressor is commanded on during the warm phase. The opposite idle-versus-highway pattern makes assumptions based on another A/C case unreliable.
