Dash cluster flashes only certain times

[vincerana]

2017 Ram big horn. Only in the morning when the sun is at an angle or when the sun is going down. Sometimes when I drive through tunnels. My dash will flash like crazy. Then when its perfectly dark out its fine, or in the middle of the day its fine. I dont have a hat on the dash covering anything up. I checked all relays and everything. Its like the light sensor acts weird when the sun is rising and setting near dusk and dawn. Just put a new battery in and its still happening. It happens on hot days and cold days. My truck is completely stock. I dont know what it could be.

Possible the sensor is failing but It could just be the effect of lighting in the tunnels. If I had to guess, your headlights are flashing too...

Mine did this about 4 years ago. It would only flicker in bright light conditions and when the headlights were off. If I turned the headlights on it stopped flickering.

I finally got tired of it and bought a used cluster on eBay, which fixed the issue.


I remember researching this problem back then and it was pretty common. If you search for "cluster flickering" on this site, you'll find a weeks worth of reading material.

This is a good point, I guess we should ask (both you and the OP) is/was the whole dash flickering or just the instrument cluster?

Mine was only the evic screen.

It's been a long time, but I seem to remember having taken it apart to diagnose, and deciding replacement was the best option.

Here's a thread on it from when I took it apart to diagnose, in the last two posts of the thread

Flickering premium cluster. Replace with standard 3.5" cluster?

I thought I had this problem fixed a dozen times in the past 2 years, but it always returns. I've reseated the fuses, tightened every ground cable, cleaned every cable connectors, used dielectric grease on every connection. The problem is intermittent, and the problem persists, no matter...
