Re: Tailgate and back window problems
You need to check that you have an electrical signal to the lock when the alarm is activated.Use a testlight/probe.Unplug at rear lock activating unit.hold test light to positive side and activate alarm,if you have a power signal the lock activator is suspect but also check that the mechanical part of the lock is free moving and not resistant to being moved.Does the central locking work on the back doors with the original system?If it does the problem is with the immobiliser.If it doesnt then the lock activator area would be the likely place to look for the fault.

I have a similar problem, my tailgate stopped working with the outside handle and the remote but can be opened manually from the inside. I don't have an alarm so there is no problem with that but did you get a solution for the tailgate problem that I could try?
Hi, check that the pipe going to the rear washer jet hasn't become disconnected from the jet (inside the tailgate). If it has the water from the pipe runs down the inside of the tailgate and contaminates the lock assembly and alarm microswitch. Remove the tailgate liner to check. Hope that helps Matt.
No there is no bypass. The Motor in my tailgate crapped out on me last year partly to do with a rusted out tailgate that let water in! I replaced my tailgate, but in my research found that the only way to get the window down was to remove the inside panels on the tailgate, un screw the cover plate, and then unbolt the motor to allow the window to drop enough to open the tailgate. Once the tailgate is down it will be easier to see the internals and remove the motor. Hope this helps you
take it back to the people that did the body work, it is assumed that when they do the work the locks would be working correctly. Anything they touch as part of the work has to be fixed before giving it back to you unless you agreed to the problem.
First thing: Try using the key to move to the locked and then to the unlocked position. If this works, open the tailgate... This also pretty much tells you what the root cause problem is, which is a pressed-in plastic post working its way out (see below).
If no bedliner, just remove metal plate inside tailgate and actuate by hand inside to open. If bedliner, first use a small screwdriver to carefully (don't scratch paint) push in latches at either side of tailgate to open/lower tailgate (if locking/unlocking as above did not work to lower gate and gain access). Next, use two blade screwdrivers to pry out the "buttons" that hold the ends of the tailgate liner where they wrap around the sides, then remove bedliner piece and metal plate, etc.
Once you have access to inside of tailgate, you will see how the mechanism works by pulling up and down on the handle while observing. You will probably find that the slide mechism that locks and unlocks the mechanism has been allowed to move such that it cannot unlock/allow movement of the latching mechanism. This is usually the result of the pressed in plastic anchor being worn/loose. I had some success with cleaning thoroughly with alcohol or brake cleaner, allowing to dry and then using super glue to hold it firmly in all the way. Still have to hold handle up when closing gate and keep key on hand to unlock every time opening, but it was a free repair...
I had the same problem. I was able to get the back window open.
I took the the 4 screws off that are on top of the inside of the door (where the tailgate window latch is).
Got a metal coat hanger. straightened it and made a hook at one end.
carefully pushed the plastic part of the tailgate towards the inside
slid the coat hanger straight down (to the level of the tailgate key/handle) to catch the door latch from the inside and pulled up.
that will get the tailgate open.
then you need to take the rest of the screws out of the lower part of
the tailgate to get at the latch assembly. Carefully take the plastic off. (you will need to take the
nice black insulation stuff off the metal part of the door carefully so you can replace it and
tape it up if necessary after fixing the latch.)
peel the insulation off the metal part of the door, you will see the
assembly rod has come off the latch and will need putting back in place and a
little sqweeze to stay on. really bad design I guess, but since I fixed it at
140000, I haven't had any trouble with it at 166000.
The micro-switch is fitted inthe lock of the tailgate.Try opening the tailgate and manually close the lock and see if the boot light and the dash indicater light go off,if not,replace boot lock.If the lights go off,tailgate not closing properly,adjust the boot lock catch.Good luck
