How to replace the battery in a 2005 cadillac deville.
The battery is located under the rear seat on the passenger side. The replacement battery is a little more costly given the fact that it has the need for venting sulfuric acid fumes. If you remove the old battery and do not place a temporary power supply on the systems computer, you will possibly cause may things to go wrong. The temporary power supply insert is on the drivers side directly under the steering wheel. You will need the adapter plug. Your best bet is to go to advance, autozone, walmart, etc., and plead with the manager to allow free installation of battery you intend to purchase. Show them how clean the underside of you back seat is and there is no battery leakage. Liability keeps many shops from installing back seat battery compartments due to acid, leather, etc. I talked a kid into it at advance for 5 bucks. Otherwise, professional dealer or shop installation will cost you more on top of the already overpriced $170.00 battery. Back seat removal is easy. Pull front of back seat straight up on both sides releasing tabs, then lift it and slide rear of seat up and out. Installation is the same in reverse.
