Instrument Cluster Lighting Issues
I own an 87 gt and have had an issue for a while now to where only 3 or four of the bulbs in my dash will work properly. The hi-beam and turn signals work but nothing in the center of the dash.
I took apart the panel dim switch and cleaned it out with compressed air as it had some corrosion on it and it did help a little with the brightness but did not light any new bulbs up. I replaced all fuses as well.
Could the panel dim switch still be the problem? or could it be the the fact that i have a 140mph speedo in an 87 that im sure was not installed correctly, or could it just be the ribbon circuit/ voltage regulator on the back of the cluster?
Any help would be helpful, was expecting blown bulbs and was replacing with LED's...NOT
