Question about 1984 Chevrolet Corvette

Open Question

The instrument panel on my C4 1984 corvette works except for the speedometer, fuel gauge (which always reads FULL), and also the odometer (non digital) has stopped working as well. Do any of u guys know where i should start to look for the problem? Odometer probably needs speedometer to register mileage i'd think but need advice. Thanks for any feedback!

In my case, simply removing and reseating the IPC/DIC fuse restored the gauges to full functionality.

SOURCE: My speedometer and odometer stopped working

Your speed sensor has failed. The vehicles speedometer is not cable controled, it's controled by a sensor in your transmission. It's a easy fix, but the new sensor is about $80 to $100 depending on where you get it.

My speedometer works but my digital odometer does not work on my 2003 old alero


This is one guy's advice: Replace the speedo head, that should take care of the problem."

This site is also interesting because the guy said
General Motors cars had instrument cluster problems from 2003 through 2006. When I researched instrument cluster problems on the Internet what I found raised concerns in me. Many of those vehicles had problems that began with the instrument cluster, but eventually led to the engine refusing to start.
(an electronic instrument cluster, digital instrument panel or digital dash for short, is a set of instrumentation, including the speedometer, that is displayed with a digital readout rather than with the traditional analog gauges. Many refer to it simply as a digital speedometer.)

Volvo gle 850 1996


After I bought my '96 850, I found it had the same problem. In my case the speedometer worked fine, but not the odometer. A little research on the internet revealed that it's a common problem with these models.

There's a motor that drives the odometer separately from the speedometer, and the weak link in the chain is a tiny gear that turns the odometer when the motor runs. That gear is easily broken and even one missing tooth will disable your odometer.

The fix is relatively straight-forward, but requires you to remove the instrument panel and disassemble it in order to get to the motor housing and the broken gear. You won't have any trouble finding replacement parts on eBay that are much better made and will last you the rest of the life of the car. The difficulty level on this is about medium, but be careful when you've got the instrument panel disassembled; I wasn't cautious enough and ended up with a couple of my indicators out of alignment; my tachometer read zero when it was idling, and my fuel gauge only went up to 17 gallons when it was full, so I had to take it all apart again to reposition the gauges to get them to read correctly.

Instrument cluster is not working.


The odometer "error" is usually a BCM (body control module) problem, not the instrument panel. All the electrical signals you have lost all go to the BCM before going to the instrument panel.
It could be a simple connector problem.

Everthing on my dash (speedometer,odometer,fuel


Blown Fuse or fried Circuit board. Take to a local AutoZone, Advance, Murray's, O'reillys or a similar part house for them to check the wiring. I'm assuming the van does not use a mechanical Speedometer or Fuel Gauge.

On the plus side, with no speedometer, your indicated odometer mileage does not increase. Just keep your speed down and your tank full. Kidding, just kidding.
