My '05 TB EXT LT has an issue with the liftgate. It got locked and wouldn't unlock even via the Tech II for the last couple of weeks so I couldn't open the back. It won't lock or unlock with the door switch or the key fob. It will, however, lock and unlock with a Tech II since I have opened it up and moved things by hand. It is also saying it is open (via its switch, and the Tech II sees it as open), which means I can't use my rear wiper unless I use the Tech II. I'm not sure which part I would replace - the lock mechanism or the liftgate module. It would seem the signal comes from a different place via the Tech II than the door switch/key fob, so that might indicate the module. I sprayed the heck out of the lock mechanism and even tried to move the close switch (I think...) over a tooth so it would show closed, but that didn't do anything, so I may need to replace it to show the liftgate is closed.
Any thoughts or ideas?
As an aside, I found out why my license plate lights were out. I tried new bulbs, and when those didn't illuminate, I checked for voltage at the socket. Finding nothing, I hit the forums and found the many and varied threads on checking the wires in the rubber boot. When I took the interior panel off to look into the lock issue, I saw a connector that was unplugged. Plugged them together and guess what? I now have tag lights! I also saw other Christmas trees that were pulled out, so someone has been back there in the past. I guess they just forgot to plug the tag lights back in.
