My gauges are playing up and I'm not sure where to even begin looking.

It's a jdm bb4 prelude with el gauges. A couple of weeks ago the clock, fuel and temp gauge all started to flash in random patterns. The speedo/Rpm cluster lights also started to take about 30 seconds to turn on at times.

They all have separate plugs going to them so surely it can't be any of the gauges or sending units causing the issue.

Has anyone experienced this issue before or have any input as to what the issue could be?

Thanks

 

Sounds like a bad ground, so I would check grounds, and the connections to the boxes in the dash harness.
