Wondering if anyone can help

I was getting a code for a valve block on my ram air suspension and had it replaced after about a week seems like the drivers side drops to the ground more so then the usual lean the rams have if it runs for a bit it will rise back up any idea on what this could be

Ps I'm in Southern Ontario it has been cold this week and the temp went up today to about 0 from negative 18

I've read on the older Rams. moisture or air has gotten in line(s).
Air suspension has nitrogen and is closed system.
So to fix that issue, you have it purge and refill it.

I have air suspension on my 2021 Rebel, so far haven't had any issue.
I'm located bit north of Toronto, it was very cold.
Either they fixed issue, that older ones having, or I will also have issue after few years.

It just seems strange that when in a heated garage it levels out and stays at the correct level but when left outside it drops that one corner

not strange. normal.
If there is condensation in the line(s) it will freeze.

Based on what you have mentioned, sounds like the problem. Works fine when warm, but it's cold, it fails.

Fixing the issue, that is different story. I've seen few videos, people showing how to purge the system, and filling again.

Mine just died on me as well. Getting an over payload message and service message. Left side dropped to the stops, but the right is at normal height. Hoping when it warms up in a couple days it'll work again. Nothing in the back, but a couple duffle bags so it must be getting jammed up somehow. Regardless let the air suspension nightmare begin. Have a couple friends with rebels and they said it was good for 2 winters and then nothing but trouble after that so they've gone to springs. Still under warranty at the moment so I'll try and get it fixed, but can't afford the down time so it'll probably end up removed sooner than later.

I had a 2017 Longhorn and got rid of it because of Air suspension. Frustration was just too over bearing. Dealer kept replacing components to no avail. I've concluded that the system isn't designed for the cold climate.

Funny story around this issue…..
A couple years ago, my 2017 with air suspension was parked outside a pub whilst my son and I had a meal and, I admit, a “couple” of sherbets!
I can’t remember exactly but it was in holiday period of Xmas/New Year.
Very very cold. Came out, started truck and immediately ‘contact dealer immediately’ message sign for air suspension. Do not drive etc etc.
well, I wasn’t gonna do THAT at stupid o clock so I drove home, maybe three miles with it on stops! Like driving a brick! Wow.
Got home, went to open garage door, it had frozen to ground, one corner raised and it fell off the runners and into garage…..New house purchase this so not my fault lol.
We drove truck in, propped door back in hole, backed truck up to inside to hold it in place and went to bed!
Next day, suspension completely okay. Never happened again. Yes, I did fix that door too! What a night…….

Air suspension on a pickup in Canda is just a really bad idea. The Jeeps don't seem to have near as many issues for some reason but all the guys I know that had air pickups sold them or swapped them out for standard suspension. When it is regularly -30 to -40 in the monring nothing wants to work right and air ride just makes it worse.

I’ve owned six vehicles over many years with air suspension: Lincoln town cars, Cadillacs, Range Rover, etc. Every single one had issues around 50,000 miles. I converted my last town car to regular suspension and noticed no difference except it didn’t change the ride height with additional weight. I’m personally done with air suspension. I think that for the initial cost and maintenance and repairs, it’s just not worth it.
