Interesting happening this weekend - 500K trip with van each way and happened both legs, aircon works perfectly(cold and blower fan works as normal) till about 3-4 hours into the trip(little kids so stop regularly but keep engine running depending on stop duration toilet or lunch, stop engine for fuel etc). Temps dont go over 103 for water (hills @ 100/110, auto with lockup 67-90 (90 ish uphills unlocked), Cat bank 3 on ultragauge poor mans Exhaust Gas Temp spikes to early 600's(hills)...blower fan speed even on high is weak as the proverbial, and the air temp coming out is not quite warm, but definitely NOT COLD. Stop car for an hour, and the aircon is working as per normal again... on auto at 18C, fan speed blows you away and the air is cold...
2016 MQ from new, never been re-gassed...cabin filter and re-gas were the first 2 thoughts, but then blows you away after a "pause"...so kind of ruled them out atm...
Anyone have any idea's/thoughts?
