I just wanted to place a quick post and let people know the simplest things you should always check first. I replaced my 85 mph gauge cluster 2 months ago and it has never worked. The gauges were all going haywire. I did everything i could think of to fix it. Nothing worked. Well today i had a brainstorm to look at the fuse. Guess what? I replaced the fuse now they all work great. So for everyone out there save your self some trouble. Check the fuses first.
