Flickering LCD in my Speedometer

All,

I've searched enough to know the 97's had issues with the speedometers going bad. Here's my issue: in the LCD displaying mileage (aka odometer), I've recently noticed the LCD is becoming faint and will occasionally flicker. It hasn't gotten to a point where the LCD completely goes blank, but I'm worried the unit may be going bad. Any recommendations on what to check?

Also, I've had several check engine lights related to the "Vehicle Speed Sensor". Could these two issues be tied together? I also was curious if this could be related to a few recent rains we've had. Could moisture play any role?

Any respectable speedo shop can replace the lcd screen. The original miles will be retained. It is quick and easy . Also cheaper than buying a new speedo.

Weather does seem to play a part. They seem to flicker and go blank during rainy days on units that are starting to fail. I doubt your codes have anything to do with the speedo display.

I can refer you to a good speedo shop if you do not have one locally.

Which speedo do you have? Yours should be analog.

I have the same problem with my 97 D-90 speedo. Anyone have a good speedo repair shop I could send it to for repair?

Yeah North Hollywood Speedometer can fix the odometer LCD issue, they did mine and were able to retain the original mileage and now it works petfectly. Did you get the code(s) associated with check engine light?

I did, don't remember the exact code, but it's the Vehicle Speed Sensor. I've gotten the same code several times on my handheld reader. I'm not getting any other codes. I guess my conundrum is do I replace the speed sensor to try and trouble shoot that to start with, or do I try and trouble shoot the speedo. I think they're unrelated, so I may just go ahead and replace the speed sensor since there's clearly something going on there. Then, if the LCD is still acting up, I'll send it out.

Not related issues. Depending on the cost to fix the original speedo, you can also buy a new LR one and hollywood speedo will advance the miles to match. Just another option if the first is too much.

The local shop we use charges between $185 - $295, depending on what it needs. They also usually call that it is finished before I even can get back home. PM me if anyone wants their number. I have no affiliation with them.

FWIW, I took my Speedo out to get the ODO fixed and it threw the Vehicle Speed Sensor code. Sent the Speedo to North Hollywood Speedo and with a bit of begging, they were gracious enough to turn it around in 3 hours (I have to take it to the DMV next week). Their service is amazing... cost was $250 + tax. Code went away after I returned the Speedo.

That's normal. On the 97s the vehicle speed sensor goes through the speedo and then on to the ECU. So if you unplug the speedo the ECU never gets the speed sense signal.
