Fuel and Temp. Gauge Problem, Please Help

I have a 95 wrangler and the gauges work fine until i turn my headlights on. Once I turn my lights on, my fuel gauge will go past E and my temp gauge will exceed 260. If I turn the interior light adjuster thing all the way down, turning my interior lights off, they will read normally again. Also these two gauges are the only ones that don't light up when my interior lights are on. I changed the lightbulb but nothing changed. I only have problems with these two gauges; my tachometer Speedometer oil and battery gauges work fine. If anyone could help me i would greatly appreciate it.

Inspect the flimsy circuits on the back of the gauge cluster. They are possibly shorting out.

Could be a ground wire issue. I'm having a similar issue with my tachometer. Any time I press the brake, use any lights, it zeroes. I found out the ground for all the gauges on a 95 yj is located between the battery and the motor on the firewall.

The gauge circuit board is notorious for bad connections causing one or more gauge and lights not to work.

Remove the gauge cluster and each gauge. Clean the contacts on each gauge and circuit to each gauge. Check for damaged circuits on the circuit board (more like a film, really).

Pay close attention to the wire harness/PC board connection, clean well.

Reassemble and test. It is not unusual to have to do this several times to get everything working (had to do mine 3 or 4 times before everything worked)
