Default rear hatch constantly/randomly unlocking, 05 GT

if the car is locked, its fine. once unlocked, the rear hatch keeps unlocking randomly. driving or parked. it wont open up unless you use the key in the hatch, turn and lift like with the key. the electronic release doesnt work at all. the outer most cover fell off in my hand, clear plastic with one long wide copper strip in the middle.

along with this the power locks while unlocking are really loud and the rear doors wont unlock via power.

didnt see a fuse just for the rear hatch.

where do i start? pretty decent with electrical testing and whatnot so you guys can get technical n all

There's a post on here explaining how to replace the rear hatch switch with a cheap Radio Shack pushbutton. It works great, let me see if I can find the link.
Oh, and if one or more of your locks are loud, that usually means that the lock motor is on the way out or has gone out (stripped). So yeah, you need to change that.

Here it is. Be sure to read the whole thread.

I echo sanatanadharma's input, the electric pressure switch on your rear hatch is truly the weak point in the electronics of the PT locking system. Unfortunately when the switch fails it invariably fails in the open position which in turn burns out that portion or function of the RKEM.

I've posted a thread that's now in the "how Too" section of the Forum with photos and text explaining how to replace the switch and RKEM units. The same photos can be seen in my control panel under pictures & albums

It's not all that difficult a project and with Bubba's offer you at least have access to another switch. There's another Forum member that had posted as having a few matched RKEM and remote units available reasonably. SO you might come out of this a lot cheaper than I did when I replaced them on SOOO BIG. I put out a bit over $200 for the parts. Good luck.

Happy PTin', ptprice

Excellent info. Thanks guys!

Those of you that have done the push button swap, does the hatch stay locked when the vehicle is locked or is the rear hatch now always accessible?
I'm assuming I'll be using the wire that unlocks the hatch from the pad, therefore it will only be accessible one the vehicle is unlocked. Just want to be sure :-)
