Hey all! I am new here, but have a very frustrating item on our new (to us) 2018 GMC Yukon XL Denali. The buttons on the exterior door handles that lock and unlock are driving me crazy. I think these are called passive entry buttons (not sure on the actual name). Both buttons on the passenger side work just fine, but neither of the ones on driver side work. They depress, but nothing happens. I have checked all fuses that may be associated with this system and they are good. I have went thru settings on infotainment system with no luck either. Please tell me someone else has seen this problem and can help me out! Thank you so much!
