Gluster gauge won't illuminate

Hello hayeizmyhome...Very low mileage for a 1990 model. However... this is usually around the mileage interval the dreaded instrument cluster, panel and dash light failures start...lights will flicker, then go out, gauges will start going up and down, lcd's will become hazey and hard to read....etc.
The instruments are illuminated both day and night while the ignition is on.
When the ignition is off, the panel goes dark and you can’t see the gauges at all.
The lexus has an electronic circuit board behind the inst. cluster that has been the problem. Very expensive repair if done by dealer.
*TIP* This circuit board can be repaired if you know a good electrical technician much cheaper.
The recommended timing belt replacement interval on the LS is 120k...water pump should be replaced also, the timing belt runs the water pump. The LS has a non-interference engine, meaning if the belt breaks, no damage will be done to the engine...
Hope this answers your questions..and your lexus runs for many more miles...with proper care and maintainnace, it will.

Hi Jorge. Por ahora, s?lo conduce a la misma velocidad que todos los otros conductores.

Where is the fuse for the tilt steering wheel

It seems no one knows the answer. It may be a circuit breaker instead of a fuse. Or maybe a fuseable link. I found several YouTube videos on replacing the motor, or replacing a plastic gear that's part of the system. If you watch them, it may point you to an answer.
