Hoping to get some direction from some of you Fiat gurus here....

I have a 2014 Fiat 500L Trekking and yesterday the blower stopped working after a rain storm. Worked fine up till then. No fan/heat/AC on any setting.


Thought I read somewhere if it was the transistor going, it would work on the highest setting but it doesn't. The dials light up, but no air comes out.


Will be checking the fuse in the morning, but any additional advice or direction would be greatly appreciated.

What sort of set up do you have is it air con with a hot and cold knob and an air con button or is it a digital climate control set up with lots of buttons and screens you can set the temperature by ?

Depending which you have makes a big difference.

Hi all I have the same problem on a 500L with digital climate control.

no air blowing on any setting, the control lights up and I can change the temp but nothing happens the fan does it kick in.

Have changed 30am fuse and swapped the T08 relay all to no avail still no blower blowing.

Any help gratefully received

More often than not it’s a failure in the control module that manages the speed of the fan. In the old days it was a £10 pack of resistors that could be easily replaced but with climate control they have a digital controller for fan speed, sadly this can be very costly, and will likely need a trip to the dealer.

Thanks for the reply, will go to dealer and post the cause when found.
