When I lock my vehicle with the keyless remote every door locks but the rear lift glass is not locking. I have checked the fuses and have looking inside the latch to see if the wiring is plugged in which it was. Have no clue what to check now

Sounds like lock actuator probs. Will need to remove cover(s) and inspect carefully to see if does have power and grounds.
