Make/Model: Cadillac DeVille
Year: 1997
Mileage: 87,000

Seems my driverside power window motor has seized up. I have a couple questions though.

How hard is it to get the door panel off? I've done it before on a Bravada, wasn't to bad.

There is an Airbag inside the driverside door. What precautions must I undertake in order to not set it off?

Is the Power Window Motor pop riveted on?

I hate to Bump this, but I would really like to know before I get home tonite if there are any precautions i need to undertake with the driverside door airbag.

First of all, you'll need to disable the SIR system. Pull the negative battery and fuses for the SIR as an additional safety, then wait 15-20 minutes for the backup power in the SIR system to discharge.

Then, there a just a few (maybe 3) screws although I don't know the exact locations on the 97. Mine is a 95 and the screws are in a different place on my door panels. Once the screws are out, the door panel lifts up and off (has inverted "j" hooks that latch into the sheetmetal inner door). Be careful of the harnesses, you'll need to disconnect them before you pull the door panel completely away.

Once you have all that mess off, there is a vapor barrier that need to be pulled back or off (you'll need to reglue this when done with repairs - the adhesive is a one-time shot).

Not too big a deal, though doing the window motor itself is not something I've had to tackle yet, so I can't say with any authority how hard it is to do.

Thanks for offering your help, but after doing some reasearch it appears you have given some very poor advice. I have to post this not to embarass you but do keep anyone safe who may find this topic.

DISCONNECTING THE BATTERY WILL NOT DISABLE THE SIR SYSTEM.

To disable the SIR system you first must pull the 50 AMP IGN1 fuse in the Maxi Relay fuse box.

Then once you have removed the door panel disconnect the plug that is color coded yellow.

But I'm still wanting to know if the Power Window motor is riveted on?

Ok,

Pulling the battery will not _immediately_ disable SIR. One needs to wait at least 15 minutes for discharge to occur if doing it this way. That's because there is standby power integrated into the SIR system. I only posted those instructions as I did not have the specific related fuse #'s for a 97 at my disposal. If my advice was not clear, I apologize profusely.

I'm not wanting to sound defensive here, just trying to explain why I posted it as I did.
Yes, I would recommend doing the proper way per the FSM, to eliminate any possibility of inadvertant deployment. As you seemed to be pressed for time (as I read your original post) I was simply trying to give a timely reply in the simplest way possible.

Anyway, in the interest of doing the "CYA" thing I guess I will steer clear of posting ambiguous non-model specific instructions regarding critical items like SIR systems in the future.

As to the rivets (or lack thereof) hopefully someone else on here has done a window motor on a 97 and can say for certain.

Shutting my trap now,

I really appreciated your help, just didn't want to get anyone hurt. The battery suggestion waiting 15 minutes may or may not work according to the information I gathered. The reason as you stated is the SIR system has it's own power source fed from the battery. Since a head on collision it would be likely that the battery could be destroyed it would still need to deploy airbag.

No problem,

15 minutes is usually sufficient for the reserve power to dissipate, although I will concur that it is not guaranteed to be enough time for that to happen. As well, after re-reading my first reply, I see that I did point out that the fuse should be pulled:

quoting myself here:

"Pull the negative battery and fuses for the SIR as an additional safety, then wait 15-20 minutes for the backup power in the SIR system to discharge."

Admittedly I did not offer a specific fuse by number or function name. This is where I fell short. Further, after thinking about it some more simply pulling the fuse may not immediately disable the SIR as this circuit is feeding the 12V to the SIR [SDM] module, and the reserve deployment power is integral to the module (after the fuse so to speak) so one either has to:

1. Still wait 15 or more minutes for discharge of reserve power -OR-

2. find and disconnect harness(es) to the inflator modules to isolate them entirely from the SDM (sensing and diagnostic module, which contains the reserve power) which is the ideal means of eliminating the chance of blowing a bag off while tinkering around. I know I did this when I pulled my steering wheel, simply no excuse to take chances.

So, I still stand corrected as I can see where my posted procedure was not outlined as completely as it should have been.

In any case, I wanted to clarify this all so nobody reads and follows inadequate advice while working on something as touchy as the SIR system. I'd not want to be the cause of someone doing hundreds (or thousands) of dolllars in damage on account of something I typed in haste.

Of course this being a more or less public forum, anything said here should be treated cautiously, especially where safety critical items are being discussed. Always verify/double check information as even the best of us are prone to make mistakes.

I haven't pulled a window motor since the mid '80's (Eldo) but it was riveted and I would suspect they still are.

I am parting out a 94 deville, and I think it is safe to say that the window motors are the same. Let me know if you are interested. thanks
