Power lift gate issues
 

I have a 07 Tahoe Ltz with some power lift gate issues. The gate will raise with no issues but when I press the button to close the gate it will come down about about 6 inches then go back up. At that point it won't do anything until I push the gate up then it will do the same thing, down 6 inches then back up. Any help would be great.

I encourage you to take the vehicle in to be inspected by a certified technician.

If you have any additional questions, please feel free to contact me.

Can you close it manually? It sounds like it might be whatever causes it to reverse if it hits something.

switch
 

my guess is also the switch/position sensor, since the motor part seems to work.

I can close it manually. Where is the position sensor located ?

Sorry to dig up this old thread but was this ever resolved? My 09 does the same thing randomly.
