Alright bought and installed new gas struts that were suppose to work. After install they are too strong to allow the lift gate to come down and still have same problem that it wont lift the gate either. Leaning torwards motor could be worn out.Before you start tearing into everything, have you verified that your hydraulic struts that hold the lift gate up are in good shape? If those are weak, the power lift gate will not work, the motor doesn't have the power to lift the gate without the assistance of the gas struts. To check this, open your lift gate manually. Does it stay up on it's own? Is it really heavy to lift? If so, your struts are bad. Easy fix, parts are available on Amazon or RockAuto, or if you want to spend more, can go with OEM from the dealer. They are also relatively easy to replace yourself, take about 10 minutes total, plus finding a 2X4 or similar (I used a broom handle) to hold the gate up while you change the struts.
