Dash Instrument Question/ Help

Hi Y'all,
recent Hiace Owner (98 super custom G)

I have been noticing that inconsistently my speedometer/tachometer/odometer will just shut off. Showing that I am going zero km/ zero RPMs/ no odometer increasing. once it turns back on it'll jump back to where it should be on all three but I find I have to jam on the "Reset" dash nob a bunch to get it to go. could be a loose wire? just wondering if anyone has had the same troubles before.



beginning shows me pressing the button to turn it back on, then pressing it later which turns it back off again.

thanks!

Realising now that this should be in Sparky my bad
