2020 Express AC/Defrost problems

- In my 2020 Chevy Express work van, the HVAC controls stopped working and defaulted to defrost.
Found that the vacuum lines (yes, vacuum lines) came unplugged.
The plastic looks like it may have deformed from using the heat this past winter.
Anyways, really bad design.
I don’t have a fix yet. But since it’s under warranty, I’ll let the stealership deal with it.
Thanks for watching, hope this helps someone!!
So they used the same garbage part for 23 years? Had that on my 97 Express.
A lot like the Astro 🤣
Keeps costs down I guess.
Great video. Took me straight to the problem, grateful for videos like this!
That way on my 2002 express van. Passenger kicked it off because it was hanging down.. Blower went to defrost while driving.. Plug it back in. Works perfect. Thanks
Straight to the point. Thanks for the video.
Yeah, Man. My stepdaughter kicked my vacuum lines loose. Yellow and Brown. Reconnected and tucked away better.
It’s mind boggling isn’t it ? Vacuum assist anything on these is ridiculous. I lose all AC every time I climb a steep hill ! 🙄
I’m having that same problem too now.
There’s another vacuum connection on the passengers side strut tower that is known for disconnecting itself. Check that. It’s behind some stuff, but easy enough to get to. Sorry no video on that one, but there are some on RUclips.
other day was like wtf are these wires hanging so low . zip tie them up high. now i going to have to check to see how tight i did that
Such old tech for 2020 van. Guess it keeps costs down.
What are you pointing to..that's the problem didn't do it for me..
There’s another vacuum line in the engine compartment that comes off to check that
