The fuses and relays are not inside the door panels, but are in the fuse boxes. Under the hood and inside the trunk. You have to take out the carpet trim and the fuses are on the left front of the trunk I think.
Removing door panel, if like my 97 - there is a screw behind the lower rear lights that turn on when the door is opened. You have to pull the lights off and there is a screw. Then pry up the panel at the front that has all the power window buttons (I think, it's been a while since I did this, it might be the seat control panel.) You must pry the panel up, then there is another large screw that can be reached. Then, there is the little triangle shaped trim piece at the front top of the panel. There is a push-in panel pin there, you gently pry around this piece until it pulls out. There are NOT push-pins all around the edge of the panel - it is retained by screws, this one pin at the top front, and it then have J hooked shaped connectors on the panel that push down into U shaped connectors in the inner door.
So, basically, when you have the screws out and the one pin out, you just pull the panel straight up and it's loose. There are all kind of electrical connectors still attached. The lights, the window controls, the speaker wires, etc, etc. And, you probably have a side AIR BAG! Before starting any of this DISCONNECT THE BATTERY! Disconnect the air bag connections from the panel. If you blow an air bag, don't blame me!
What you are trying to get to is the window motor, which is probably failed. Pull the power connector off the motor. Put a volt meter into the two wires of the connector. Reconnect the battery. Push the window button up, you should have 12+ or - volts. Push the window button down, you shoud have 12- or + volts (the reverse of what you get the other time). If you get this, the wiring and the switch and the fuse, etc are all ok. If not, start working on getting power there. If you have the correct voltages, the motor has failed.
Put a couple of strips of duct tape up the window and onto the top of the door frame. This will keep the window from falling. There are 3 bolts holding the motor in, it's real easy to remove. After bolts out, you might have to wiggle it around a little. Take the motor to any auto parts house. Check carefully that the motor sold to you is identical to the old one. At Autozone, their part numbers are messed up, I got a right hand one when I needed the left hand one, so, take the old one in. It should be about $70 or so.
Buckle it back up. Your are done. The worse part of the job is getting the door panel off a Cadillac. The motors are all bolted in and easy to remove.
#22 of 63 Stalling 98 deville
Dec 22, 2008 (11:43 am)
Well I took the car to the dealer and was told that the crank sensors were good and that the ERG was faulty. Had it changed and that still didn't fix the problem. Afterwards, the throttlebody was cleaned and they said that should do the trick, but once again it did nothing. Now I'm being told that the IAC is most likely the problem. Is there anyone who can really help me? Some of the DTC codes are: PCM P0603, IPC B1552, ACM B1341, TCS C1255, PZM B1552/1558, and MMM B2144. Most these didn't show until I disconnected the negative cable from the battery. Also they all are history codes and not current. Please help, I'm at a loss:(

Also, can someone explain the body control module on a 1998 deville, and where it's located? Thanks!

on the stalling on the 98, I was told to change the Idle Air control valve, but I really don't trust the dealer being that they told me it was the EGR valve and 500.00 later the problem was still there. Then they said that EGR just had to go through a reset phase which is not true. Also the throttle body was cleaned out and the problem is still there. I'm really tired of this problem and wish I could just get this resolved. Good luck on your problem and hope you find it.

no other answers on stalling Deville besides Crank Position Sensors??????????

Well went out on a limb and changed the IAC valve and it seemed to have fixed the problem of the stalling. the valve is two screws and right on the side of the throttle body on top. Real quick and easy fix plus no maintenance cost on your own labor. So if there were a lot of things changed including the CPS's, change that valve and you should see the problem disappear. Remember to disconnect the neg cable from the battery for about 30 sec to reset the ECM. Good luck out there!

#29 of 63 Power Window Problem
Mar 21, 2009 (11:50 am)
I have a 1998 4 door cadillac deville with Power Windows. There is a contol pannel with 4 buttons on the driveres door to control each window. I recently rolled my drivers side window down and now , when i press the button to roll it up, the window will not roll up as if it is not getting any power. The other three are working fine and getting power but not the drivers door. has this happened to anyone else and does anyone know what i need to do to fix it? I first thought that it might be a fuse, but i assume if its a bad fuse then the other three would not be getting power either??

The motor probably died.
