Purchased a deslugger

[Trey Hardy]

@Doubeleive Going to run it until it breaks and then I’ll fix it. Would like to dig into why the rear AC isn’t working eventually

Wassup with your rear ac?
I had to change the controls on the back of the console to get mine working then a couple recalibrations when it would strangely start blowing hot air instead of cold air. My rig messes the actuators up anytime the battery dies or is unhooked for whatever reason

I installed one for a while but didn't like the way it cycled the compressor. Hasn't been a problem in the summer, but I still have it so I can always connect it back up if I have trouble in the winter.

Same here. I installed one 5 years ago and removed it a year later. It's sitting on a shelf in the garage in case I decide to put it back on someday.

I'm wasn't experiencing any problems with the compressor, I just bought the deslugger thinking it would help prevent problems, but I could tell every time the ac would cycle on it (HVAC set to auto) would take a bit to actually blow cold. Kind of hard to explain, but I could notice it and didn't like it.

@Trey Hardy The rear air will blow hot when set to hot but when you set it to cold it only blows ambient temperature air.

I think refrigerant isn’t flowing to the rear because the AC lines under the rear or the Tahoe never get cold

Yea that’s likely mine get freezing and is always dripping condensation from the lines and rear passenger side
Try running by a auto shop that’s not scam artist and get them to hook the ac machine on it and suck/refill the Freon and check for any leaks from the o rings on the ac lines

I’ll get a video this morning of what’s happening.

Now that I think about it this problem first came up after I did the AFM delete. I suspected that the harmonic balancer wasn’t lining up with the AC clutch 100% but not sure if that would cause this.

The deslugger comes today so by the end of the week I’ll know if this resolves my complaint.

Here is the video from this morning, the sound wasn’t as loud as normally is

When this happens, does it shake the whole truck like it is in gear? I keep getting this random cold start she-bang like there is a band still engaged in the transmission for some reason. @NickTransmissions

You'd have to describe what you mean by 'she-bang' in a bit more detail (Please start a new thread if you'd like me to dig into it w/you further and I'll respond there) but it's unlikely to be your 2-4 band, assuming you have a 4L60E.

I installed the deslugger. It certainly helps the problem I was having but I do notice the compressor cycling more often that ideal.

Mine is doing the exact same.

@iamdub I think to fix it the refrigerant would need to be sucked out and have that orifice tube filter thing might be gummed up if YouTube has any say in it.
