I have a 97 f250 4x4, pulled the gauge cluster to clean it up and change incandescent to led. Before pulling the cluster the right side of speedo and left side of rpm wasn’t illuminating, assumed it was bad bulbs. During bulb swap I did not pull anything but the gauge window off to buff up and replaced it then switched bulbs out, that’s it. Re installed and same bulb positions weren’t illuminating. While lights were on I figited with the bulb holders while look at the gauges and there wasn’t any flickering. Pulled the plug and checked the contacts on the back of the cluster, all were lined up and intact, spread the contacts on the plug out a bit to make sure they were touching and still no change. I’m at a loss now. Any help would be much appreciated.
