THe only way to check these lift gates are with a scanner on the body control module data screen.
I have had so many problems with these, they have multiple internal switches and if one doesnt work or gets stuck. the system does not operate properly.
I have stopped testing these units and just ended up replacing them whenever there was a problem with one.
I bet i have replaced a dozen this year.
I would recommend checking the jam wiring and making sure there are no breaks in the harness.
Like i said the only way to check these are with a compatable scanner, and I have stopped testing them because its always the latch.
I would just replace the latch assembly, because i think one of your switches inside are faulty.
Now, If you replace the latch yourself, you will have to recalibrate it with a scan tool also. So itmight be a good idea to have a repair shop check, replace and reset the latch.
I hope I have steered you in the right direction.
I appreciate any positive reviews and I am always available for follow ups after ratings!
