2013 Rear AC not cold

[Travismohr88]

I have a 2013 Explorer XLT and the rear ac will not blow cold. When I turn it to hot the temperature of the air does not change. I can not find any info on this. Any help pups be greatly appreciated.

Welcome to the FOrum Travis.
It is possible you are having issues with the blend door or the actuator. I'm guessing that the blower motor is working?

yes blower motor is working and I was able to pull the temperature actuator and it seemed to be working fine.

Its probably the same issue I posted just before you:

2011 explorer rear expansion valve replacement.

Hey all, I seem to be chasing a cooling gremlin. I had a small freon leak which was corrected. Next, no cold air on the passenger side so I replaced the blend door actuator. Now, the rear vents are not blowing cool air. I've read a few older posts that it's probably the rear expansion...

Rear expansion valve is most likely the culprit, however I'm not finding much on how to fix this as in how to videos.

I manage to find this, so I hope its in the same location:

Location of rear AC expansion valve

Hello, Can somebody tell me where this is located on a 2008 Explorer? My rear AC blows not-so-cool air while the front dash vents blow out very cold air. I have searched and read a lot of threads online and the consensus seems to be that the rear expansion valve could be the cause. I verified...

I have not looked for the part yet, was trying to confirm how to do it before I tackle the project. If I find the part, I'll let you know.

@Travismohr88 I ended up fixing my issue by adding refrigerant to the system. I was about 15 psi low, once filled up the back vents were cool again.

Closed systems aren't supposed to lose their contents. You probably have a leak somewhere. Look around in the day or get a UV pen light and shine it at the various a/c pipes at night time all the way front to back. Look above the muffler as well, this is my guess here. These Fords all have fluorescent UV dye in them so it leaks out an oily green (you can see the green with naked eye) that glows bright in UV light (dark conditions). You can usually smell the refrigerant leaking when the system is running in the driveway.

Dye from the factory? That's reassuring....

It's released into the system from the condenser/receiver dryer element. If you replace one of these ever, you'll see it as a few bright yellow balls at one end of the bag of desiccant.

Not sure for your model, but in mine (2016) the refrigerant cycle thru the front and back unit, they are connected together.
I know it because my rear hoses connection has a leak and I lost all of AC (A/C Rear Line Leak)
Also, the dealer told me they are connected together.
So I would not point right away at the refrigerant as the issue. Probably something around the rear unit.
BTW: colour additive is not that uncommon, help for quick troubleshooting.
