2003 Suzuki Aerio Q&A
2003 Suzuki Aerio Question: Rpm and fuel gauge dash lights are very dim.
Not sure if this is exactly your problem or not, but there is a TSB (Technical Service Bulletin) which pertains to your vehicle in regards to the instrument cluster illumination. Basically the TSB recommends removing and replacing the 4 illumination bulbs in the cluster itself. Replacing the bulbs would require removing the instrument cluster itself. Seems to be a pretty straightforward repair since the labor time says about an hour to perform the task. Hope this helps - PRESTONFITZ
