Front suspension works fine rear won't raise
I have a 2007 gl450 that the front suspension works fine but the rear won't raise. Had the pass side rear airbag blow, changed it but rear still won't raise.
Could this have anything to do with the rear lifgate sensors?
I was reading something about another pump under the rear seat could this have anything to do with it?

Correct. Airmatic needs to be reset via das when pressure has been leaking for a long period of time and the system has disabled the offending circuit. Replacing the faulty component is not sufficient in this case as you need to "tell" the system that it can pressurize that circuit again.

I have had the truck at 2 diff shops and one says pressure relief valve in the compressor??? but why would the front work and not the rear? another says height adjustment sensor, but why would BOTH rears not do anything?? I'm really at my last nerve with this truck!! what kind of regular rear suspension can i put in this truck?

I would assume the reset has been done it has been to 2 shops both with the star system. So besides the valve block could there be anything else that would give these symptoms? Thank you for your help!

there are star actuations for airmatic that will help troubleshooting the valve block.

What parts are there? I Beleive it's pressure from the compressor to the valve block then to the individual corners? If not please inform me of the components I'm trying to research online but have no luck

as i said- there are manual activations in das that can be used to determine if valve block is good.

Yes thank you! I just don't feel like getting screwed out of another $200 so I'm trying to figure it out on my own. If the front suspension is working I would ASSUME (I know, I know) that the block is getting power, so it would have to be a stuck valve. Or am I way off still?
