My Lexus LS 430 navigation and controls screen is blank and is not responsive most of the time, though it starts working for a few minutes now and then and gradually becomes irresponsive. Sometimes it says that the external system is not connected. In the rare instance of working, it works for short periods esp when the car is either very hot or very cold. This is when I select my temperature, climate settings for next few weeks. I have heard simeone mention that it is the computer hard drive that is messed up and really the tiuch screen itself. Any proven repair suggestions and price fir fixing appreciated! Thanks!
What makes this problem better or worse?
Extreme temperatures ease the problem, else is persistent
How long has your 2004 Lexus LS430 had this problem?
RepairPal Certified shops can diagnose and repair your 2004 Lexus LS430. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
This is something that would need to be looked at by a shop. It's very possible that the entire control screen assembly will need to be replaced. With an older car you can go with a used unit but it's best to have it diagnosed at a repair shop so you know it will be fixed the first time.
