Thumbs up! I repaired 1987 Corvette digital dash cluster myself

Hey everyone, I just repaired my dash in the 87 coupe. Followed Bryan Thompson's article on batee.com and got the dash to light up as it should. Ordered linear polarized film from polarization.com to replace the sunburned film on the front of the lcds, and it looks and works great. The only thing is the speedo is showing km-h, the switch on the control panel is in english, but it doesn't change anything when I move it from english to metric. Is there something else that changes the speedo from km to mph? Thanks, and I hope everyone out there who has a digital cluster that isn't working will follow the instructions and buy the film to fix the sunburn so they can have a great working cluster for less than a hundred bucks.

Having to edit my post. I had been doing a lot of reading up on these dashes, and I remembered the problem with it going dark when the headlights or park lights are turned on. This is happening to mine, but the turn signal indicators come on and stay on. I replaced the headlight switch about a year ago, but I think it still might be the problem. When I installed it, it worked perfectly, but after a while I noticed the headlights don't close when you switch back to park lights. You have to turn them completely off to get them to close, then turn back to park, and the headlights don't open until you turn them on. Any ideas on this? Thanks
P.S. I think I'll go ahead and invest in the headlight switch anyway, just to get them working properly, if nothing else.

Well that's cool. I swapped mine out for analog gauges before it could break.

Looks good too

Can't wait to get rid of mine! Hasn't worked since day one and can't justify putting the time and $$ into it to repair it knowing I'm yanking it

To the OP, post some pics though It's always good to do something yourself and have it turn out well

Just one thought on your edit: The headlights don't go down when switching from headlights to parking lights. Mine does the same thing and I thing this is normal. Sure does make changing the headlights easier.

Good going on the DigDash Catman!!!

That's normal operation for our headlights/parking lights. Both of my C4's do that. It's just the way the system is designed.

Cluster Repair Polarizing Film

Just picked up an "84 in need of some TLC (1st vette) and I'm diving into a cluster rebuild. Nothing works on the display right now, and I mean nothing. So anyway, I've read a few fix-it articles but I haven't found one that talks about replacing the burnt film. Looking for some help about that and would also appreciate other recommended sources for general cluster repair.

to tell you the truth, i just did my LCD's today and honestly.... i wasnt hard at all. for the past 6 months i have been driving without my dash, then read this post, called George from Alight out of San Antonio, Tx (210-545-6867)and ordered PFA-SM polarized film. 2 sheets that were 10x6 for 32.00 plus 7.80 for shipping. took about 1.5 hrs to rebuilt once the dash was removed. to me, 40 bucks is a hell of alot cheaper than replacing the whole dash (few hundred bucks there). i am among the few that had a sunfaded film and good LCD's. reinstalled the dash, hit the key, and BLAM. looks like the space shuttle is about to launch. i have never been so happy to see the dash light up like this. it is a very easy fix. and cheap.

Great, but where's the DIY?

Got any pics of your analog dash? Sounds nice but I couldnt find a pic of it in your gallery.

Unhappy

hi guys...the digital cluster is a real nightmare for many of us,some months ago i tried to fix my faulty one ,using Batee's indications suggested in his tutorial .I had to fix the ground connections (3 wire),then i completely disassembly the cluster,arriving to open the two twin board and creating a new ground connetion between the boards soldering a little wire on one of the two board,i replaced the little bulbs on the cluster,then very carefully i re-assembled everything.when i putted in place the cluster and it worked like new!!! But in some day the cluster was black again... Now i place some analog gauge in the dash using the factory multiconnector line to obtain the needed inputs (tachometer,fuell,oil pressure,water temp)
