Question about 2003 Cadillac Deville
Will not turn over, lights work, heater works, power seats work, the radio, windows, trunk opener does not work, headlights stay on do not dim when turning key.
This procedure usually works:
·Check the battery cable connections:
Make sure the positive cable, makes a good connection at the battery and at the starter. Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine.
·Check the battery the simple way, like this:
Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.
·Check the starter and solenoid:
If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
If the starter spins and no crank, the problem is most likely the Solenoid's bendix gear is stuck.
Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck bendix gear.
·Make a simple test of the alternator:
If you can, somehow get the engine running, measure the voltage at the battery. It should be at least 13.6 volts to properly charge the battery.

Starter relay, starter connections, or bad starter.

You could try checking the fuses to see if any are blown, if the fuses are all good then it's possible the door switch is bad or not making a connection from dirt or debris, the door switch is generally located insdie the door at the hinge or its a push button switch, when the door closes it pushes the switch in, the switch may also be jammed in keeping your lights from turning on.

Did you recently have a loss of power to the car? change the battery? if so, you need to reset your system. My husband and I just figured this out this weekend. His sunroof hasn't worked in two years and it turns out you have to reset all the power options in the car. Google 2000 cadillac catera %calibrate ETC% loss of power, you'll find the step by step instructions for recalibrating the car's computer and resetting the power options

Check all fuses both inside the car and under the hood. Consult the owners manual for the location of the fuse boxes.
Otherwise, have a mechanic troubleshoot the cars electrical system.

I have the same car with the same problems except for the tail light. My radio works when it wants. This morning I went out and my trunk was open and now it will not stay closed. I dont know what to do. I have no idea where to start with fixing the radio. Did you ever find a solution.

I've got a 97 deville d'elegance that has issues similar to these. Last year the red anti-theft light came on and the car wouldn't start-took it to the dealership and they replaced the PCM? (the main brain for the system) for $900...the guy told us the wiring was so corroded he didn't want to mess with it much. Today the message started flashing on the dash that says "anti-theft problem/ car may not restart" but it still turned over in the driveway a couple times so I am hoping I can reset it. The wiring system is jacked and will probably need to replace the wiring harness completely. Doubt its worth it. Not a secure feeling with 2 babies in the back seat in the middle of winter....
