Hey

A few weeks ago my car decided to suddenly not lift itself. Put it in jackmode over night and now it wont raise at all - currently riding on bump stops. Compressor does not run by itself, but when hooked to 12v battery it runs fine. Bought a fix kit for the compressor. Checked all bags, no leaks. Switched relays, nothing. Checked all lines from compressor, cant find any leaks. No broken wires that I can see. Even tried with a new air suspension module.

Tried to run the compressor when it was hooked up, but car did not raise. Could it be a faulty valve block?
Also I measured the voltage in the relay outlet and it only gave me 3v constant. Im not that technical of me, so not sure if thats just normal.

Any help would be appreciated as this is making me crazy.

 

It sounds like the compressor and airbags are fine, so the issue might be with the valve block or relay control circuit. A constant 3V at the relay output isn’t normal — the system should send 12V when activating the compressor. Double-check the wiring to the valve block and the fuse connections for corrosion or partial breaks. If those are okay, a faulty suspension control module or ground connection could be the culprit.Visit
