Gauges on the right side do not work

[airplane99tr]

I am new to this group. I am rebuilding a 1995 Explorer.
The gauges on the right side of the panel do not work.
The Tachometer seems to be sticky or has a bad ground. If you hit a bump or hit the top of the glare shield sometimes the tach will turn on for a while then off again. The Oil Temp and Fuel Gauge are also inop. Is there a bad ground wire on the left side? The right side gauges and speedometer work fine. This vehicle was not driven for the last three years. I know how gauges work and it seems there must be a common problem to all three although I would think there would be a common buss for both the right and left side.

Any chance that a critter could have got in and nibbled at the wiring? After three years I wouldn't doubt it

You just may have to pull it out and see what you can find. Just unplugging and reconnecting the connectors may help.

Rick -

I will check for partially eaten wires. Did not know if it was a circuit board for all the instruments in the cluster (right side and left). From what I see on-line it looks like it might be two halfs. Then it could be a critter attack. I hate cluster gauges. I will update

There is probably a cluster "plug" in the backside of the cluster. If it has been partially pulled out, it might cause the problems you're having. Be a good place to start, though, and you can spray some contact cleaner on the connector while you've got it out. That might be it, too! good luck with it, and definitely watch out for critters while you're in there!

Thanks for the tip! I will pull that plug and clean it.
