I have an '03 IS300 and the cluster is giving me a weird problem. It was intermittent before but now it seems to be a hard fault. The tachometer is reading zero, the brake light warning is on as is the fuel pressure light, and I also have nothing registering on the fuel consumption guage. It seems to have no effect on the car, traction control, cruise, speedo, all seem to be alright. I went through the wiring diagrams and could not find anything common with all 4 of these items. Please help if anyone knows! Thank you!
