Svt Gauge light dims, quits then work again?

I've gone back years in searches - nothing specific - other than remove, replace
Symptom:
After about an hour of driving, the gauge lights start to dim, flicker then will usually quit. I have pretty red needles sweeping across a dark dash.
Next drive cycle, they work fine. For about an hour...

Intermittent is a bad word, but any specifics would be appreciated.

Thanks,

-T_T

Dash ground is behind the drivers side kick panel. Remove it and take a wire wheel to both sides and reconnect it. Do the same with the main ground under the airbox under the hood.

Hopefully, this will correct the issue.

Tommy, I've got the same problem on my '04 EAP SVTF. Exactly the same symptoms too. I believe you are referring to the electroluminescent lighting on the gauges. All of the other lights, odometer, radio, HVAC, remain lit and can be adjusted via the dimmer wheel. I have my suspicions that it might be heat related, and I have started keeping the heat low and on the feet rather than the dash, and it seems to help. I was thinking it might be a resistor heating up and causing the problem.

dremmel R good

Thanks, cleaned them up. We'll see what happens, but it was interesting to see that the ones under the airbox snorkel are copper. They were coated white. Applied ACF-50 to ensure no more corrosion.

Right, symptoms happen with the heater on for the drive cycle. If the grounds fixes it, I'll be happy.

Tommy, keep me updated if you don't mind. The last two nights have had me finishing the trip to work with no speedometer, tach lighting.

Thanks.

It does sound like you have something heating up and shorting out.
