My 1992 saab 9000's hatch wont open when i put the key in and turn it, there is no release tab in the hatch area and no buttons on the dash to open it. what do i do to get it working? there isnt a saab workshop where i live.

Radio is an internal problem. A/C, have your mechanic friend check the high and low pressures, along with the outside temperature when he checked it. Repost, I'll tell you what's wrong. And the hatch, there is a rod that unlocks it, it has came loose in the hatch. You have to climb in back and pop off the top bezel for the hatch. Then remove the screws on each side of the bottom bezel. Start popping it out, enough to reach down and open the hatch. After it is open, remove the screws at the handle on the bottom and finish popping it off. Replace the plastic tab that has broken for the rod. I suggest replacing all of them.

No you can't. You can bypass a key or module, But the ECM still needs a signal to start and run the car.

there are two buttons on the hatch don't push the one on the outside push the one on the in side where you put your hand to open the hatch

Before doing any other troubleshooting on a 2003 Ford Focus hatch release problem, try THIS... The hatch release button is a triangle. Push the button on the very bottom point of the triangle. For some reason, mine did not work when pushed in the middle and only works when I push it at the very bottom point... slightly off in any direction and it does not work. Strange but true.

Make sure your battery is fully charged and check the teeth on the starter and flywheel.

If the fuse is okay, check to see that the latch is not bound in some way, and that it is properly lubricated. A dry latch sometimes will not release.

Since you changed the battery .. the key needs to re-sync with the system.
According to some web searches the following may work:

• Put the key in the ignition
• Then hold the unlock button down on the key for a minute, while the key in the ignition

Let us know if that works

could be the solenoid on the starter is going bad. but best bet is to get a whole new stasrter as a new solenoid comes on it. solenoid is almost as expensive as getting both together

have you checked your inside door lights,if they are off, you,ve a blown fuse, think itts number 22 on fuse board.i changed mine and it solved my problem....

the metal rod came off the inside. You need to come in from top with a slim jim to open and then work on the door by taking panel off. Get a locksmith or call the local dealer and ask who is there SAAB roadside assistance. Also Cadillac dealers have a roadside service.
