No power to airmatic compressor, tested cables, replaced fuses and relay, rebuild junction fuse box in passenger floor board, and also tested valve block level actuator sensor. This was the only way i could get power to the compressor. I have also followed wiring from compressor to passenger SAM Module (fuse box) and still no current flowing through wires. Im stumped. Anything else i can check? Comments appreciated!
Update: Ended up converting to coil conversion. Customer could not maintain let alone understand an airmatic system. I probably could have ran a switch to supply power to turn on and off the compressor but i would also have needed a way to monitor the quantity/lbs/bar of air in each strut and that would have been too complicated for the owner to use lol. But this is just a video clip of what i did to test the compressor since i wasnt getting power to the connector and neither replacing fuse and relay or new compressor did not solve issue.

Great job brother...my s 500 been sagging passenger side rear only daily...well today both rear are down .and now compressor isn't engaging.... front are still up...i have my s430 model i retired for parts now...i am learning from youtube but yours got right to the point.... thanks a bunch...now if ya know how to squeeze, more horsepower from these s 500 feel free to inform us ...I've done pulled cats off and mufflers... flowMasters from axle back woke this benz up...now let's focus on suspension...

I turned my car off and heard a steady stream of air coming out of the hood area and then I heard a clunking noise that was loud coming from the pump area. Is this the relay switch not telling the aromatic pump to shut off and it’s violently shaking due to insufficient air flow?

@davidjohnson1778 2 жыл бұрын

It may be the compressor or just the lines connecting to it. Check all air lines connected to it. Its common to have air leaks going into the small plastic external filter as well. Not sure about clunking noise though, thats weird.

@davidjohnson1778 4 жыл бұрын

Are you sure your air struts aren't blown? Usually the top mount of the airmatic struts in the S class seperate and leak from the top. Verify your air struts can hold air first then check the level sensors also. If those are in the wrong position it will either raise too high or drop super low. In the instance of that video, I just used power and ran it straight to the pump to verify it worked still. It ended up being the airmatic control valve that was causing it to not get power.

@@bevhoney-b2184 remove the compressor and try running power to it or do the bypass i show in video to verify compressor works. Most likely the top of the front air struts are leaking. You can use sealant to seal the top of the strut but if they are completely blown they will need replaced. Better to just convert the whole thing and never worry about air shocks again.
