Help...

I am not able to open my liftgate with the key for or manually. I am able to open from the inside of the vehicle. What is going on, I am at my wits-end.

Don't get my wrong, I love my Armada, but she is getting on my very last nerve.
What can be wrong...

Also, I hear beeps coming from the rear, the cargo area. Is this an indicator of something else being wrong?

Please help. I don't want to take it to the dealership, they know what's wrong, but wants to charge an arm, two legs and etc.

Thanks

What year do you have?

Can you open the trunk door by hand? Does it lock?

When you open the trunk door and you try to close it with the fob, does it close on its own?

Do you hear the trunk motor attempting to work?

Have you always had this issue happen since you had the car?
