Do a search as there must be fifty threads on this same issue already. Plus there is no waiting for a response.

Re: 1972 chevy c10 dash lights help
If it's just the lights that illuminate the cluster...
Have you checked the variable resistor/spring on the shaft end of the light switch? If the knob is not rotated occasionally, corrosion may form. The spring/resistor can also break. This would affect all the cluster illumination lights and is possibly the easiest thing to check. I'd start by just rotating the knob back and forth several times prior to pulling the switch. If this doesn't work, you'll need to do more complex troubleshooting. Here's a picture that shows the variable resistor. |
