Hi Guys,

I have the following issues:

1. My steering wheel has multifunction, however the left side with buttons is not illuminated. Is it a bulb responsible only for the steering wheel buttons' illumination or it is something general.

2. I have an issue with my climate control. The left sided vents blow only cold air eventhough both (left and right) are set to highest possible temperature. The right side is ok and it blows hot air. (I have changed the thermostat)

- The next issue is that my front window defroster does not work, however the rear one works. Please tell me how to fix it

Thank you in advance ! !
 
There is no bulb in your steering wheel , only leds. Technically a led could be bad and im not sure if those are in "series" with eachother. So if 1 fails the other wont work either....

The problem with the warm/cold air is because of the servo's ( small motors ). Search the forum for "servo" and you will find the problem. Biggest problem is that there is a big chance you need to remove the complete dashboard to fix it because the Stilo was build around the heatermatrix......
 
1. About the steering wheel, the right section with buttons is illuminated and works, therefore it is strange that the left side does not get illumination, however the buttons work perfectly.
 
Good chance one of the LEDS has failed. Left and right side are 2 separate prints with on both sides 2 connectors ( if you have abarth oherwise 1 per side).

You need to remove the airbag before you can do anything. ( allankey needed )
