QuestionIs there a difference in an instrument cluster and a instrument cluster relay? Are they the same part? Or do they have different functions? The digital dashboard on my '89 chevy beretta gt is not working. (fuses and bulbs have been replaced)
AnswerHi Sharon,
That is a common issue on that vintage digital equipment.
Your cluster relay and cluster are two separate items. The relay, as you call it, is really called a CVR (Constant Voltage Regulator) and only determines what to tell the cluster to display on the gauges dependent on the information, or voltage reading the CVR receives from the different sensors. It does NOT control the lighting or illumination of the cluster itself so if the LED's aren't lighting up anymore, the problem is with the internal ballast which cannot be replaced separately.
Looking for a reputable service technician? My advice on finding a good technician is: Steer clear of the dealership and 'chain' stores like Firestone, Sears, Pep Boys, Monro Muffler/Brake, Midas, etc. as they usually only employ ONE ASE Certified Tech just so they can say they do and chances are, that guy is the asst. manager or manager and is not in the store to diagnose/repair vehicles anyway. Find a service location in the link below or get some names out of the yellow-pages and do a drive-by. Garages that employ ASE Certified Technicians will be marked with the 'Blue-Seal' insignia. If unsure about whether a place employs Certified Techs, just ask to see their credentials. ALL ASE Certified Technicians will be PROUD to show and display their certificate(s).
Thanks for the question, I hope this information was helpful to you.
