2010 E350 Passenger side AC blowing hot
Tried doing a search but couldn't find something that addressed this. The passenger side AC is blowing hot in my 2010 E350. Drivers side is cold. All settings are set to max AC. what could cause the passenger side to blow hot like that?

Use a $150 "cReader elite MB" scanner to read live data and faults from your A/C Module.
Then condition may all become clear to decide on fixes.

This system is 100% computer driven, as good as it gets.
If I had to take a guess: 80% chance you have a tiny leak.... that may simply be refilled without spending thousands.

LAUNCH keeps changing specs back and forth
much like MB part numbers: the latest genuine CPS is a perfected leaker unlike original ones that were maintenance proof.

I am dealing wit AC on my 2014 right now as well. The old iCarsoft does the job.

It's easy to overlook the basics, get overwhelmed with countless data. The best part is fault setting criteria to work out misleading codes.
An handheld scanner shows fault codes and exposes live data under 5mn out of the glove box... no computer degree required for perfectly good troubleshooting: KISS principle.
