My 07 LTZ has a Power Lift Gate that has worked flawlessly until the other day. After I opened it I went to close it by pushing the button at the bottom of the gate. It started to close and then stopped and opened again with 3 chimes like something was blocking it from closing. I checked to make sure nothing was keeping it from closing and tried it again. Same thing. It started closing, went down about a foot before reversing and opening back up. Anyone else had this happen?
