My Dash Board Cluster Won't work on my 1994 Lexus LS 400.
Can you help?

Thanks for choosing FixYa and welcome. Something is draining the battery, eventually killing it. Have you had starting problems in the past? Is the car cranking? Have you checked anything, such as alternator, terminals?

Hi Patricia, Take the vehicle for a diagnostic scan. The problem may be with the mapping sensor or ignition system, which may include the crankshaft sensor or the cam sensor. I doubt that the problem will be with actual fuel system because it misbehaves at a specific engine speed. By taking it for a scan the technicians will be able to pin point the problem for you. Regards John

The battery may be good but doesnt have to be. A worn altenator can sometimes not charge and it'll ride till it quits on the battery as it goes down but won't restart cause it's to low. Something may be staying on when the car is parked. Will it always restart if it hasn't sit very long but if it sits longer it won't? his is a sign that the car has a draw. If it does, idems that didn't come with the car are more likly than the cars orginal parts to be badly connected. Battery cable connections to the battery are the number one cause of a no start and with the cables removed all the touching parts should be shiney or clean them till they are and then tightly install them neg cable last and then see how you do expecially if you find any dirty places in the cable connection. Everything needs to be good any prblem is the problem

Might be the rheostat which regulates/dims the dash light... If you need further help, I’m available over the phone at https://www.6ya.com/expert/robert_573a00ba7e399076

problem could be stopped up fuel filter if car dies when you drive car has a lean fuel system need more gas on acceleration which is a rich fuel mixture.

The starter of your car is located and hidden under the top part of the engine, in the very center. They locating the starter inside the engine. You may also need intake.Hope this helpful.Best regards.

if it is for the power steering system or the hydraulic cooling fan then you only need power steering fluid.
