Several weeks ago i went for a mountain bike ride like normal, opening the rear hatch and closing it before heading out. I don't know if it didn't close totally or what, but i came back and opened the hatch and that is when my issue first started (i think). None of the buttons would close start the motor closing. I pushed the door closed, but the motor wouldn't engage to pull it closed. I couldn't push it closed, either.

I got home and got to the manual release and could then get the door to latch by pushing it closed, but none of the motorized functions will work. If i want to open the door i have to use the manual release.

I've checked all the buttons on the dash and the power lift function is on, but none of the buttons will open the door. The fuse in the engine tested as fine.

The button that locks/unlocks on the rear hatch will lock/unlock the other four doors, but nothing happens with the rear door (no clicks or thuds or anything like that).

Reading around the internet makes me think it's the lock actuator but i admit to not knowing how to test that. I've got a voltage meter and have removed the interior door panel, but i don't know which part of the mechanism to test.

Does anyone have any other thoughts about what it could be and/or things to test? I'm also struggling to figure out which part i might need. I'm not the most mechanically inclined, but would like to try to avoid going to the dealer if i can.

thanks

Any time an electrical component doesn't work, check fuses first.

thanks. I did check one in the engine compartment labeled for the lift gate (pink, 30A maybe?) and it looked and tested fine using a meter. Is there another one that is involved (so far this is the only electrical issue i've noticed)?

Thanks for the reply.

I had this issue happen a few more times and have figured out that the easiest thing to do to resolve it is to reset the computer. It's what the dealer would do. In fact, i was waiting for them to check it the second time and the service manager made an off-hand comment about resetting the computer. I ran outside, popped the negative, waited a few seconds and put it on and the lift gate worked again.

It's a terrible design, but my solution is now to just pop the battery terminal and deal with having to reset my clock and automatic window function after.

Now that i own a code scanner i'll see if it shows anything the next time since that might be easier than resetting the computer manually.

I hope @donner got his problem solved. We haven't herd from him in a while.....

not sure how i missed this. Been chasing other issues i guess. Sorry about that.

the solution i mentioned previously still works fine. If, for whatever reason, the things stops working i just pop the negative terminal connection for a few sections and it resets the computer. I'm sure there are other ways of doing it that might be easier, but it's worked fine for me. i also try to be more careful to keep from tripping the safety setting, so that has helped.
