Traction control and theft lock
The traction control light in these years is usually a bad wheel speed sensor built into the wheel bearing. Cost around $600. The audio may be as simple as entering the unlock code. The deceleration could be a hundred different things so you'll have to pay to get that diagnosed.

The theft deterrent module or the insturment cluster or the ECM is not seeing correct info.
The vehicle theft deterrent (VTD) system functions are provided by the theft deterrent control module. When an ignition key is inserted into the ignition lock cylinder and the ignition is switched ON, the transponder embedded in the head of the key is energized by the exciter coils surrounding the ignition lock cylinder. The energized transponder transmits a signal that contains its unique value, which is received by the theft deterrent control module. The theft deterrent control module then compares this value to a value stored in memory, learned key code. If the value is correct the theft deterrent control module sends a random generated number to the transponder, this is called a challenge. Both the transponder and the theft deterrent control module perform a calculation on the challenge, if the calculations match the theft deterrent control module sends the fuel continue password via the serial data circuit to the Engine control module (ECM). If either the transponders unique value or the calculation to the challenge is incorrect the theft deterrent control module will send the fuel disable password to the ECM via the serial data circuit. The components of the VTD system are as follows:
• Theft deterrent control module
• Engine control module (ECM)
• Ignition key (Transponder)
• Ignition lock cylinder
• Security indicator

Can I take the door panel off and put up my power windows on 2004 CTS Cadillac
If you pull the windows they will separate from the window channel hardware. If separated there is nothing to keep the window glass held up and it will fall back down. Check your fuses for power windows, there may be more than one. Also check the power window relay(s). The relays may be located under the hood in the fuse box.
When i push the gas pedal on mhy 2004 cadillac cts it feels spongy and wont go
Your dts uses drive by wire. The gas pedal is actually an electrical switch connected to the engine computer which then actuate a throttle body motor which causes the car to speed up or slow down. If you mean the car won't acceleration then the throttle actuator is probably going out, this is common and you replace the throttle body assembly as the actuator is sealed onto it. Had the same problem with my 04 srx (which is mechanically the same as a cts). If you have a check engine light on (and you should) get the codes read first as there are a few other problems that can cause throttle problems, however they are less likely the cause.
Sunroof won't close automatically.
Is the motor receiving power? If not you have to check electrical system to locate the place that is not transmitting power. Could be a fuse/relay, switch, bad connection.
If the motor is turning and nothing happens then the drive mechanism from motor to sunroof is stripped. Not good.
