I bought a 2015 Suburban LT with an inoperable Automatic lift gate. When I try to release with a fob, the lights blink. When I try to release from the cab, nothing happens. I know how to set the liftgate to manual before you ask. I found there is no ultra micro relay at position 16 in the rear fusebox. I had a relay that fits, but I realized there seem to be no female pins to receive the relay. Nothing "grabs it" when I put the relay in and it seems to want to fall out. Upon closer look, I cannot see any metal (only plastic) inside the relay receptacle at position 16. Does anyone have a liftgate wiring diagram for a 2015-2019 Suburban LT? How hard is it to pull the rear fusebox? It looks like I have to remove the entire rear driverside luggage side panel. Is the manual correct? Is position 16 ultra micro relay for liftgate? All thoughts and help appreciated.
