Just bought a 2015 ES350 with 125K miles, mostly highway, and its in good condition inside and out. After doing an extensive couple of test rides at the dealer, I have now owned it for about two weeks and I noticed that the steering wheel control lights and lights for heat, fan, etc dont come on at night. They have come on twice, but as soon as the car is turned off and restarted that evening, they dont come back on and basically do not operate. Being a noob with this brand, is there a switch, wire junction or fuse that may need replacing???? Appreciate any input and thanks in advance.
