Look in the interior fuse block. It is located on the drivers side of the center counsel, just to the right or where our right leg would be. You will need to remove the trim panel. The fuses will be labeled on the inside of the panel.

Go to AutoZone , O Reilleys, Pep Boys etc where they sell auto parts to the public cheap. They will also give you advice on the problems with your car. Get a CHILTON BOOK, ( It is much better than a Hayes Manuel. ) it cost about $ 23- $ 25. It is $ well spent.It will tell you almost every step of the way. You can also call the stores above if you shop there and they will give you advise if you get stuck. They help you so you will get confident and buy parts to fix things.

I have 2003 Saturn Ion. I had this problem over and over 2006 - 2008. IT IS THE IGNITION SWITCH. IT IS DEFECTIVE IN ALL ION'S.The replacement may be defective also, not sure. Mine was driving fine, went ino store for 1 hr came out stone cold dead, would not start and key **** in. Had to have towed to Saturn. They said it was battery and replaced battery.I said this did not make sense. 6 yr battery only 3 yr old , never weak start, never run down, in summer? It happened again 2 mo later. They tried to say battery , I said no. They checked battery. It was fine. Could not find problem. They did total electrical check. It happened again 1 mo later. drove into feed store. Went in came out it happened again. I got jump from someone 30 min later and started right up. 2 wks later same, I got jump 20 min later started. 1 mo late same. Sometimes it would just start up. Took to another Saturn place. They said Ignition switch, saturn was having big problem with this on Ions. Got changed and no problems for 1 yr. I was talking to repesentative at Saturn Headquarters. I told the problem. They said the ignition switch has an electrical component, or it is hooked to electrical component. THEY SAID IF I HAD JUST SAT THERE 20 MIN WITH KEY OFF, THE COMPUTER CHIP FOR IT WOULD HAVE RESET ITSELF WHEN IT COOLED DOWN AND I COULD HAVE STARTED IT EACH TIME. IT WAS BEST TO GET REPLACED AND NOT WORRY, BUT THIS WILL HELP YOU IN A STRESSFUL PINCH, UNTIL YOU CAN GET THE IGNITION SWITCH REPLACED. NOTE: Go to Auto Zone , O 'Reilleys, Pep Boys etc, get a repair manuel , CHILTON $ 23- $ 25 , for your year , make, model car. CHILTON IS MUCH BETTER THAN HAYES MANUEL. It is wonderful and many things you can do yourself.

check the back up light switch located on the drivers side of the transmission

check owners manuel there is a procedure to reset it. if you don't have manuel try turning the ignition on and pressing the gas pedal down twice then turn off key and turn it back on again

If only the trunk release is not working, did you check to see if the little lever arm switch on the trunk lid at the latch assembly is switched to enable the release? Mine came switched to the 'Off' position when I bought it and it took me a few days to figure that one out.
