2011 Grand Caravan Intermittent A/C
I'm posting to see if anyone else has experienced this problem. My mom's '11 Grand Caravan Crew seems to have intermittent A/C, as in cooling. I've checked the compressor (runs as expected) and system pressures which look nominal, so not likely a leak.
At times it gets very cold, however at others it isn't so much. The weirdest part is the passenger side always seems less cold than the driver even if they are set the same.
Any thoughts? I've read that blend door actuators can be problematic, but are they intermittent? I've seen where they fail and go full hot, for instance.
I've also read there are software updates to the HVAC control unit and potentially a test mode. Any additional information is greatly appreciated.
