Iowa | slewis - 8/11/2026 16:23 Funny you bring this up. The other day my wife was saying the ac wasn't cold in our 2017 Acadia. I was riding passenger and told her it was colder than anything else I drive, reach over in front of her vent and it's blowing warm air on her side. I cycled the ac and it seemed to even out. I'm on the hunt for an answer as well.
So far I've seen things from one of the recharge cans helping the low pressure come up to a "recalibration" of the blend valve(s). To replacing one or more of those actuator valve thingy bobs. I see quite a few videos and info for the previous generation like 2012 and 2015 but not much for the 2017+ newer generation. Also quite a few are the opposite issue with passenger being hot. I'll keep looking |
