There is a D shaped handle on the side of the seat nearest the door. Lift up on it and the seat back will fold forward, and the entire seat mechanism will lift up and to the front, giving your passengers room to get into the back seat. Simply push the seat back toward the rear of the car to set it back in place; it will lock itself down once it's back in its original position.

Class 2 Communication Malfunction
Lost Communications With ***
Modules connected to the class 2 serial data circuit monitor for serial data communications during normal vehicle operation. Operating information and commands are exchanged among the modules. When a module receives a message for a critical operating parameter, the module records the identification number of the module which sent the message. These node alive messages are used for State of Health monitoring. A critical operating parameter is one which, when not received, requires that the module use a default value for that parameter. When a module does not associate an identification number with at least one critical parameter within 5 seconds of beginning serial data communication, DTC U1000 or U1255 is set. When more than one critical parameter does not have an identification number associated with it, the DTC will only be reported once. The following modules communicate on the class 2 serial data circuit:
• Audio amplifier
• Cellular telephone module w/UV8
• Dash integration module (DIM)
• Digital radio receiver
• Driver door module (DDM)
• Driver door switch assembly (DDSA)
• Electronic brake control module (EBCM)
• Electronic suspension control module (ESC)
• Front passenger door module (FPDM)
• Inflatable restraint sensing and diagnostic module (SDM)
• Instrument panel cluster (IPC)
• Instrument panel integration module (IPM)
• HVAC control module - auxiliary
• Left middle door module (LMDM) w/V4U
• Left rear door module (LRDM)
• Memory seat module (MSM) w/A45
• Powertrain control module (PCM)
• Rear integration module (RIM)
• Remote control door lock receiver (RCDLR)
• Right middle door module (RMDM) w/V4U
• Right rear door module (RRDM)
• Steering column module w/N37
• Theft deterrent control module
• Window switch - passenger front w/armored car
• Vehicle communication interface module (VCIM)
Your best bet ,take your vehicle to a qualified repair shop.
I have a 2001 Cadillac DHS. It is located under the back seat . You have to pull the seat portion up and out toward the back of the front seat. There are two litte black flat points about three inches wide that slip behind the back part of the rear seat backs. It is kind of like a up and out motion. The battery is large and heavy...you may have to take the seat completely out to get to the battery. If you have heated rear seats there is small connection you may need to disconnect to free up the seat for removal. Simple disconnect. It is a wire length connection on the rear passenger side close to the exit door threshold.
The battery has a rubber type hold down ...but the the real securing point is the plastic block that is bolted down...you have to remove the block with a socket to release the battery completely.
Seat goes back in that same motion just....slip the black points under the back of the seat and push back and then down.
Probably the best thing is a Glass shop. It sounds like a part called a window regulator is broke. Hopefully the cracking sound is just the plastic of the regulator and not electricity arcing.
In trying to do this yourself, the window has to be up and braced. Your Cadillac is a big car with big windows. Parts are a little heavier and harder to control.
You can call around for the price, tell them you "WANT TO KNOW THE COST OF REPLACING A WINDOW REGULATOR FOR YOUR CADILLAC DHS."
You have two fuse boxes below and in front of the rear seat cushion. You have to pull the seat cushion up and then pull back the carpeting to get to them. Check the appropriate fuse and replace if necessary. If it's not a blown fuse then you have a short somewhere most likely.
It is under the car on either driver or passenger side in a metal bracket, the side to side location changes on some years and models, look just about where the front seats are bolted to the body, it is round about 6 inches long
