Hello all, this is my first post to a forum so apologies if not done correctly. I recently bought a 2006 gx470 and am having issues with the height control and dac systems.
The issue I am having is that there is no power to my controls inside it seems. The raise/lower, off, comfort/sport, dac all do nothing when pressed. No movement on the vehicle and no lights changing on the dash. There is also no lights on the actual buttons along with the shifter lights being out. The airbags do not leak and the compressor/sensors work by leveling out the vehicle when weight is added/removed.
Troubleshooting: I have checked/swapped the relay and fuse under the hood and the fuse under the dash. I've also reset the system by placing a wire in the obd port and pumping the brakes. I've swapped the ahc ecu on the driver floor panel. I've swapped out the physical buttons for dac and ahc controls. still no luck. Any insight to this issue would be greatly appreciated.
