Rear liftgate won't close
I'm having a hard time trying to diagnose the problem with my 07 Armada liftgate. It will open from the button on the dash or keyfob button. But will not close for some reason. I have pulled the interior panels to see if I find anything out of the ordinary but I haven't.
If button on the dash is pushed to close it,I get the 3 beeps but nothing happens. The rear close/cancel isn't working at all as well. I've tried disconnecting the close/cancel switch. But that didn't change anything.
The only thing I'm almost positive is not normal is while the liftgate is opening,I hear and see (since I have the interior panel off) the latch mechanism cycle as it gets to the fully open position. I'm leaning toward the latch mechanism or possibly the close/cancel switch itself. Any advice would be appreciated. Thanks
