Speedometer LCD Issue
Hi All,
Anybody have any experience with the speedo LCD going a little wonky?  This happened suddenly. Some of the LCD elements are faded, and there are some that show up (RANGE when in MPG mode, other digit parts, etc.) when they aren't supposed to. Seems to be fairly random as far as which ones. It has gone back to normal once or twice since it started doing this, but usually goes wonky again a day or two later. The odometer section is unaffected, so I'm OK on fuel monitoring, and I can pull a fairly reliable speed off of my GPS head unit. Of the issues to have, this isn't so bad...still a bit of a nuisance though

Re: Speedometer LCD Issue
Well, All you need is to replace the LCD. the cluster itself it probably fine, the LCD tends to be the issue. I had it happen on my 89 with the 91 dash, I ended up swapping the LCD only with no issues..
The challenge is finding one. You can buy a 90-91 6K tach Cluster and swap JUST the LCD and that will work too

Re: Speedometer LCD Issue
I came across this web site for restoring the LCD panel.
BATEE.COM Click on DIY Articles Under 1990-1996 Repair Click on Restoring the LCD Panel (90-96) Check out video of this process. DIY kit for $59.95 + 5.95 plus S&H I may have to do this on my ins panel soon. can't see some of the information. John 1990 white/black #2546 one of a few auto (4l80E ) eq. ZR-1's |
