I took my truck to Frederick Toyota of Lebanon, PA Tuesday to get the rear leaf TSB done. When I got the truck back yesterday I noticed that the light behind the AC fan control and the light behind the air circulation button are no longer working. I had installed a headunit three weeks ago and after the install the fog light button was no longer lighting up (may or may not have been related to my install). My question before I call the dealer is has anyone had their lighting affected weeks after installing a headunit. I don't see how it's related to the AC lights since they are different wiring harnesses but I wanted to check before I put the blame on the service shop since they should not have been messing with anything electrical.
