Hi everyone was just looking for abit of help

When I got in my car this morning at 4.30am the outside temperature was showing 21. Was just wondering where it's actually located and how I would fix it or what the problem might be.

Any help would be great

Mine does this too. In summer this year it was always reading 35-40c (slightly optimistic). I have no idea where it's located though, sorry. I've always assumed it's just another Fiat electrical mishap

Likely to be in one of the door mirrors. See if there is a 'pimple' under one of them, that'll be it. Not sure what you do next though.
