Well they used to work and now they dont glow the one that shows how much fuel l haveleft does not light up either

It looks like you're having bulb problems. If anything in your dash is not lit up when the headlights are on, a bulb needs to be replaced. You should be able to get replacements at your local auto parts store. You will have to take apart the dash to get to the gauge panel. If you can not figure out how to do it yourself, you will need a service manual that will show you how to disassemble the dash and change the bulbs.

It depends on what year and model car u have. More than likely u r going to have to replace the whole cluster. It is not cheap either. l have had a few probs come in like that, and have had to replace the cluster as a whole. It does not take just a light bulb. Remember, u bought a Lexus, they are exspensive, and so are the parts.
