The lock on the back hatch was all broken when I got the car. I first went to replace the lock on the hatch and it all fill apart, the inside and all. So I was going to just going to use the auto unlock inside but it doesn't work.

Do I look at the inside switch first or the outside cylinder? I all ready checked the fuses, I don't have a one out.

If the lock fell out as an assembly you can just open it with a screwdriver. It the lock is damaged it is still available from GM.

Do you have access to the inside of the trunk now? From your description, it sounds like you have the trunk open, went to work on the lock mechanism, it fell apart, so you want to use the electric trunk release for now instead of fixing the key lock?

If you are trying to operate the rear hatch switch with the hatch open it won't work. It gets its ground througn the metal strap thet the latch hooks onto when it is closed.

If you simply hook a jumper cable from the trunk mounted servo to a solid ground it should work.

Your right, I am not going to spend $100 or so fixing the lock and key set up on the hatch that I can open with a screwdriver at this point. I would like to get the power hatch button inside to work and make a plate that will block the key hole, "so just not anybody can open it". The inside switch hasn't worked since I bought this car, with it open or closed. Can anybody tell me where is a go place to start looking, inside switch or outside cylinder, or wiring between, remember the fuses are all good and I'm walking out the door as I finish this to go get a new test light.

First thing to check is if the release solenoid is dead. This will require a set of jumper cables and a small screwdriver. Unplug the solenoid connector. Use one wire of the cables to connect the latch or solenoid to ground, like an engine bracket. Connect the other wire to battery positive with one clamp, and to the screwdriver shaft with the other clamp. Touch the screwdriver tip to the terminal inside the solenoid connector, this should cause the solenoid to fire. If it does, use another scredriver to close the latch and try again. If it releases ok, then the next thing to check is the switch.

The most common problem with the switch is that someone pushes down on it because the little trunk symbol is on the bottom. This snaps off the indexing key inside the switch, rendering it junk. The easy test for this is to gently push down on the switch and see if it goes all the way down with no resistance. Normally it will not go down at all, whereas it will go up with minimal resistance. If the switch is bad you'll need to get another one.

Next is a bit more complicated. There are switches in the park brake handle, the ignition switch, and I think in the auto tranny shifter linkage that all act as safety interlocks for the trunk. What makes it hard is that every year Pontiac changed around how the interlocks work and I never can remember them all. You will need a schematic for your year car to trouble shoot the wiring, but first you should check the easy and common problems as listed above.
