I have a lexus 470 gx, and the height control is not working no air in my suspension it feels like a lowrider. the compressor is working (after removed and checked) but it does not work when installed..before it stopped working the height control light flasehed and then it did not work anymore..anyone have any ideas as to what it may be.

 

Feels like a "lowrider"? Seriously! Try searching the forum, plenty of threads addressing the problem with potential fixes.

 

What you require is to replace the Height Control Solenoid Valve & the Compressor Assy. If you go to the Autozone, and get the Fault codes, you will see that there will be a DTC code store C1735. The cause is due to moisture intrusion into the Height Control Solenoid Valve, which is just right on top of the Compressor. If you are covered with Lexus Comprehensive Warranty, you can save up the dollars and have the stealerships do the job. Otherwise, the parts are bit high. There is a TSB to this effect SU002-05. hope this helps
