2010 E350 Passenger side AC blowing hot

Guys,

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?

Mike

One of the flap actuator is calling for service or low in refrigerant ie. leak!

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.

How could it be a refrigerant leak if the drivers side blows cold? Wouldn't a leak result in hot air on both sides?

Found two different readers I'm guessing the original and a v2.0 which one do you recommend:

This Mercedes has a smart controller that can prioritize limited cooling for driver only.

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.

I would buy the cheaper one $120 instead of $190. It will pay for itself the first repair!!

The only differences between the V1.0 and V2.0 is: Having an internal battery and variant coding as well as portrait and landscape screen.. unsure if the processor is also different.

-- the portrait unit already has variant coding and internal battery and just got a fresh update

-- I don't know what's may be desirable in the landscape unit ?

It has variant coding? Hmmm okay I stand corrected : ) if so then the only difference is landscape and portrait plus an internal battery.

portrait unit does have a built-in battery to manage AOS powering down.

I dunno, it's not their first/second release...

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.

You can buy AP200 for $59 and have advanced scanner with Mercedes software. Just beware about subscriptions.

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

That works too but the other scanner is cheaper, if you don't need the functions of the Launch no need to spend more. For the full deal, get XENTRY.

AliExpress links are a mess these days. The link lists full price, but in the app, it shows a heavy discount.
For example, a snapshot instead of the link,

Hmmm I mean I don't ever use that site, forum members recommended a different site I think it was called kingbolen or something, they have a warehouse in the usa, they sell Launch branded scanners along side kingbolen branded ones.

HANDHELD VS. XENTRY

XENTRY is a professional expert tool with a tough learning curve. It's not a casual tool for everyone.

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.
