I ended up having to replace a module on the back of the cluster at a cost of over $800. The whole cluster is over $1,500. Not a cheap fix but you can't safely drive the car without it!

I have the same problem on the driver's door of my 05 LS430. I removed the actuator assembly but now cannot get it back into the car. The latch part will not go around the window track, even though I removed the two bolts that hold the track to allow it to "float". It came out fairly easily, but getting it back in is a real !Removed!! Anyone have any links or suggestions?

OK, time to jump in on this thread. I have an 2003 RX300 with 113,000 miles. When the check engine light came on, I took it to my local guy who had recently replaced the timing belt and water pump. He checked the codes, but had nothing, so I went to another local garage I trust. Codes showed a Bank 1 lean condition. Since plugs were way past due, I had them put in new ones at a cost of about $300. The three back plugs all were very carboned up, and the mechanic told me that was the sign of a bad O2 sensor. I found a Denso OEM (234-9009) part on Amazon for $100, and with the help of YouTube had it installed in about 45 minutes. Reset the codes and off I went. About 20 minutes later the light reappeared. Now I am really flummoxed. I've inspected the air box, and found nothing loose. Any suggestions as to what I should try next, besides taking it to the Lexus dealer of course. Thanks!

Everything runs normally, although the navigation system is not operating with all the normal icons. The problem started while I was gone. The person I had start and drive the cars said that it was out last week, but when he backed it out of the drive it came on. Now it won't come on at all. I am going to try to remove the cluster to see if it is a wiring issue. The total lack of a knowledge base on this particular problem (both online and traditional), and the hesitancy of anyone to offer concrete suggestions is very unsettling. Normally you see several links on Google or on forums such as this. There is nothing out there. I live 50 miles from the nearest dealer and the only thing my local mechanic said was that he had four or five other Lexus owners experience a similar problem and that it came and went intermittently. This is not reassuring in the least. Does anyone out there have experience with removing the instrument cluster in an 05 LS430?

I reutrned from an extended vacation to find that the instrument cluster was not operational. No lights, no gauges, no cruise. After checking all the fuses, I contacted the dealer and their suggestion was to, and I quote: "Beat on the dash."!! After extensively surfing the wab, I located a guy in California named, The Lexpert, aka Jim Walker. I called him and he said that he was not able to be of help as he had never worked on a vehicle that new. Do any of you forum members have a idea how to fix/repair this problem?
