It may be the throttle position sensor (TPS). It is located where the intake air (from air filter) attaches to the intake manifold. The TPS connector should have 3 wires. The TPS controls the air/fuel mixture.

SOURCE: 1999 cadillac deville air wont work

There's a blower motor (fan) under the hood and up against the firewall near the center of the car that takes some work to remove. It has gone out in the last 2 of my 4 Cadillacs. Turns out if you're not real careful with the positioning of the spark plug wires they will brush up against it, and if one of them gets cracked or brittle it will "arc" and short out the blower motor. The a/c compressor should still come on (you'll hear a click when it engages) but you won't get any air blowing into the cabin, hot or cold.

The part was like $200 stock (year 2000 prices) and it took about an hour to remove it. My Caddy at that time had this damn strut bar going across the engine bay which we eventually removed to get to the blower motor.

SOURCE: 2003 cadillac deville want start

check battery voltage, if battery voltage is ok, you may need to check fuses under hood on passengers side, if start fuse is ok, you may need to have your starter replaced

SOURCE: My 2003 cadillac deville-the service engine soon

On a lot of cars the light is reset when you get an oil change, air filter etc. It's overdue for a "look see". You can always go to advance auto and borrow the code reader for free. Plug it in under your dash and will read and reset any codes

My 2003 cadillac deville dts drags when i try to crank it, I replaced the battery and starter, and it still wont crank.

Hi Able:
"Crank" to me means turn over.
"Fire" means actually try to run.
If it won't crank and you have a new battery and starter, I'd be checking the terminal connections, wires, cround connection, and solenoid. If all of those are good then we need to start checking the engine condition. Recently running or sitting for 5 years and full of rust?

2003 deville it just started to crank before it starts Wat can it be got a new battery

If you could please specify a little more elaborate for me? I don't quite understand your question? Better yet, does the engine turn over? Another question I have is how many miles are on your deville?

It could be the neutral safety switch which prevents you from cranking the engine in gear.
But it could also be the anti-theft system. The system reads the chip in the key to allow the starter to crank the engine.
Is the security light staying on ?
