As I’ve posted below I bought my ‘12 XL Denali knowing that it had a LR ride height sensor throwing a code. What I didn’t know was that the part is on a National backorder. So far no one has suggested where I might look for one, the usual vendors are showing no stock.
I needed to move a bike this week so I connected my trailer. Now the LR is sky high, and it drives a little wonky. Is there a way to bleed off the air and level out the ride height until I can source the sensor?
thanks, Eric

There's an air fitting on the side of the shock, you need to slide the metal clip back and then pop it off. The air will release. But I am fairly sure both shocks are connected to a single line with a t-fitting inline so both should be the same height. At least that's the way it is on a NBS. Also, look for a sensor on Ebay. I see aftermarket ones available.

Yes, one connected set of tubing going to both shocks is also the setup on the NNBS. If you go the route of temporarily removing the air line from the shock, also remove the fuse that runs the air compressor, so that it does not burn itself out, trying to supply air through a disconnected line.

GMPartsDirect.com has the sensor that I believe you are looking for.

Many thanks. GM parts direct does NOT have the part in stock. I know this because I bought it from them, then when I inquired about a delivery date was told they didn’t know (after charging my CC instantly). To their credit they issued a credit in a reasonable timeframe.

If you just pull the line to let the air out and then reconnect it after without turning the key on, you don’t need to pull the fuse. You just can’t leave the air line off. Which would probably result in the truck airing it up immediately afterwards but like mentioned there should be no way for the system to air one side higher than the other due to how they’re plumbed, the pressure equalizes from one side to the other. If the rear shocks are at different heights, I’d be more inclined to say the one that stays low has a blown air bladder.

I wasn’t clear enough on that. Both sides are high, and level. The shocks are new ( Arnott 2708) and the compressor is new ( Dorman).
everything was fine before hooking up the trailer. I have some more hauling to do this week. When that’s finished I’ll do the line disconnect and see where I end up.
