Power Window just stopped working

Okay guys. Do what you do best and point me in the right direction. 96 Eldo etc, passenger window won't go down with either sides button. Driver window works fine, no codes everything else is working fine. Worked just yesterday. Where do I start?

Noticed, now that it is dark, that when I try the up or down positions on either the driver or passenger door window switch for the passenger window, the courtesy lights dim in both directions.

Is that a good indicator that the switch is good and that the issue is the motor?

Also today was the hottest its been this year (100) car was in the lot all day. Any chance that these motors have a thermal switch and that it tripped?

I don't *think* they have a thermal switch of any sort.

There was a window motor recently in the forsale; may be the same one not sure also: http://caddyinfo.ipbhost.com/index.php?sho...hl=window+motor

Barry found that if he took the door apart, applied power to the motor, took the motor out, and put it back in, it worked again here: http://caddyinfo.ipbhost.com/index.php?act...=&pid=19696

Yes, the switch is good and there is some issue with the motor or window regulator (gear, jammed, etc). If the thermal breaker tripped you wouldnt get the dimming...

Thanks BBF can always count on you! :D

Do you know where I can get a "How To" on removing the door panel?

Looks simple enough, but I want to make sure I don't break the clips on the panel. If I'm not mistaken, they are molded right to the door and not replacable

I just pulled off 2 door panels on my 96 SLS two days ago to replace window motors. What you are describing is exactly the problem a weak motor will cause.

Door removal is a piece of cake.

1. Pull back on the plastic piece that surrounds the door handle area, it is held in by 4 pressure clips, and will just pop out. Work out around the handle and remove.

2. This will expose the 1 and only screw you have to remove. It is a small phillips head screw that centers the door panel.

3. Grasp the entire panel, and with moderate force jerk upwards. The panel is basically "hung" on the top ledge of the window sill.

4. Once the panel is loose, lean it outwards, and disconnect the wiring clips that feed to the back of the armrest area (power windows, locks, etc). Set door panel aside.

5. There are 3 nuts holding the window motor in place. Use a 10mm socket to remove these nuts. Pull the motor straight back.

6. Now pop the window switch panel out of the door panel, and reconnect it to the wiring harness. Apply power to the window motor. You likely may see it turn, althrough it was not moving before. This is because it has just enough juice to move without the resistance of the window weight. Keep the motor going for 30 sec or so, switch directions, and you will start to hear the motor slowing down to a crawl, and eventually stop (if the motor is bad / going bad).

7. Assuming you're replacing the motor, swap in the new one and bolt everything back together. I got my motors off of ebay fairly cheap ($19.99 + s/h). Much cheaper than the $70+ the parts store wanted and I have no idea what the dealer wants.

Good luck!

To my knowledge (which might be questionable), your '96 Eldorado is the same as the '95 Eldorado I used to have. If that's the case, then:

-Eldorado door trim panels are different from Seville door trim panels mentioned by jcobz28.

-Eldorado door trim panels (remember, 1995 I'm talking about) have two screws which must be removed. One is accessible after removing the window switch plate (pry up at the rear with a flat bladed tool while pushing firmly forward to release the retention clip).

-The second is accessed by peeling back the upper rear corner of the carpet at the lower part of the door (you kept that flat bladed tool handy, right?).

As jcobz28 said, the trim panel simply lifts up and out.

If the '96 Eldorado differs from the '95, we'll all find out when BbF posts Friday evening.

Regards,

Warren

Thanks for the pic WarrenJ. This helps understand what to look for to remove the switch bezel. My door panels don't have carpet on them. There is a leather map pocket at the bottom of both of them.

If BBF gets a chance, a scanned diagram from the manual would help.

Searched the web no DYI notes out there for an Eldo. Might just create my own and post it for the next guy! :D

Yes, I think we need a nice article on this topic. There are several mentions/discussions in the Searchable Archives http://caddyinfo.ipbhost.com/index.php?act=Search&f=3 but it would be a good topic to summarize in a single webpage for the How-To section http://www.caddyinfo.com/howto.html

Window motor replaced! The one I pulled out started working again after a few taps with the back of the screwdriver. Left it out and put the new one in. Here is a quick set of pics outlining the job for the next person.

Nice job and good pictures.. Sorry I never posted those photos, my scanner is disconnected and I am in a bit of disarray here.. Glad you fixed it. Now I see why slamming the door works. Mike
