Dear fiat enthousiasts,
A couple days ago I was driving on a hot day and noticed the check engine light (gasp!) I checked the dials and noticed the Temp Gauge wasn't working, while i was looking at it, it popped back up and check engine light went off. I proceeded driving hoping it was just an electrical malfunction. Couple minutes later at the parking lot while idling I noticed the car heatinf up more than usual and the radiator fan didn't kick in. Later that same day I also noticed the blower wasn't working anymore either!!
I hope it's a fuse problem but would have no idea which of the fuses it would be. I googled and somebody said to check the (radiator) fan ground wire, where is this located? I noticed a blue wire which seemed to have snapped off for some reason but have no idea where it would go (see picture).
Hot week coming up so i need to get this fixed asap, any help much appreciated. :worship:

Get back if you have more questions.

i think that blue wire didnt snap from anything as it doesnt look it was connected to something

for rad fan, just wire it directly to battery to see if it works or get mes and cables or bluetooth adapter and run it from there

If you know anyone with MES and the cables there is a radiator fan test in the software

The wire was just dangling there, I tucked it away so it wouldn't just be hanging there. I wrecked my punto last winter by sliding into a landpost but repaired everything, fan was working afterwards but not anymore.

Turns out it was the resistor (sensor inside the fan housing), and the blower was just a fuse. Glad I got it fixed before the hot days.
