I just noticed that the temp controls and the air flow button on my steering wheel are not working anymore. I used those controls a month back or so and I know they were working. All the other buttons on the steering including the music controls and Trip, Disp buttons are working as usual. The problem is only with the air flow button and temp control buttons. There has been no battery work on the car as well. Can someone guide me on how to get it fixed? Will it be a configuration level issue or I need to check an electrician for this? Also references of any good electricians for Prius in Islamabad will be appreciated. Thank you!
