Thank you for allowing me membership of your group. I have owned a 2004 Lexus RX300 for 3 years now and been very happy with it. Recently however, it has developed a problem with the air suspension system. It started with the compressor running for quite a long time on start up. It then seemed to deflate completely, giving a very bumpy ride. The compressor then came on when it felt like it and I noticed that just one side of the car was lowered. Now, the compressor does not run at all and the offside is still down, giving a bumpy ride. Any help or advice would be appreciated.
