Technical Trip computer

[Fiat finally]

I get no response at all when trying to use my trip computer. Pushing the button at the end of the wiper stalk....nothing, scrolling through the cluster I can find trip B and turn it on but nothing happens. Any ideas?

 

[The Panda Nut]

unhelpfully... a loose connector oŕ afailed staljbutton switch. May be try to get it out ad cleab / continuity test. Nothong easy. Could a new sash / or switch be the cause non compatibility. 2014 Panda for example didnt have all the computer functions.
