2003 Chevrolet Tahoe TSBs 571 Tahoe Technical Service Bulletins. Technical Service Bulletins, or TSBs for short, are notifications made directly by Chevrolet to help automotive technicians diagnose and repair commonly reported Tahoe problems.
What we do: We repair, rebuild and upgrade your instrument cluster - for Chevy and GM vehicles made from 1999 and up. Who we can help: Owners of Chevrolet, Cadillac, Buick, GMC, Hummer, Isuzu, Oldsmobile and Pontiac vehicles with any of the following symptoms: I did a search and found nothing using "Tachometer not working". What happened is that the tach worked fine for a while then it would work and not work until I restarted the car. It finally just quit altogether, is this just a sending unit, fuse or some other problem? :dunno: Car is 1989 325i. Thanks in advance for any help.
