Not positive about the 2000, but in my 1999 they had to take off the front passenger tire to change the battery.
Under the air cleaner ahead of the rf tire.
It is in front if the right front tire, you have to remove the fender liner to access.
To jump start a 2003 Dodge Intrepid, first, ensure both vehicles are turned off. Connect the positive (red) jumper cable to the positive terminal of the dead battery, then attach the other end to the positive terminal of the working battery. Next, connect the negative (black) cable to the negative terminal of the working battery and attach the other end to a grounded metal surface on the Intrepid, away from the battery. Start the working vehicle and then attempt to start the Intrepid.
You take the old one out and put the new one in.
I have a 2000 intrepid so I think it is the same. You have to take off passenger side wheel. There is a panel toward the front of the car that you must remove and the battery is behind it on a little tray.
Follow the positive battery cable from the battery. It will lead you directly to the starter. Driver side of the engine, below the exhaust manifold.
To change the battery in the 2003 Cadillac Seville, you will need to first access the battery that is located under the rear passenger seat. Then remove the battery cables and remove the battery.

I would check the fuses in your 2003 Intrepid. If you had a bad battery, the lights and hazards would be dim. The heater, turn signal and windows may be on the same fuse.
The battery is located under the air cleaner, in front of the rf tire. You will have to remove the air cleaner and inner fender liner to access.
