Well to start I have not checked the fuses yet will be doing that in the morning, but I figured I would post this question since it seems to be more then one possible fuse and controlling other things. Is there a harness plug that connects the driver door the the rest of the car and where is it? Not one of the switches on the driver door works (door locks, memory settings, windows, mirror controls) anything. None of the individual window controls works, but the passenger door lock controls work. I should mention the driver side mirror glass is missing and wires not connected to anything, not sure if this is looped system and something unplugged cause other things to not work. Advice anyone. Seems might just be a harness to door. If the master door control is unplugged would it cause other window controls not to work?

Okay so I was not sleepy and did some looking in the wee hours. Fuses are all fine, it does appear the window relay is missing I used the seat one seems like the same one, but not working still. The lights on the door controls do light up so the harness must be plugged in. Not one window switch works still. Now confused.

Wow I seem to have alot of codes that have to do with the door controls. 23 actual codes that pertain to it. I have each code and the description of it already. I will post that shortly to see what you think. Is it simply the door switches are all bad or something else?

Are you saying your OBD was listing those codes on your car? If so, clear the codes and with key ON, manipulate the door swtichs and then display the codes again.

Or are you saying those are all the codes that can relate to doors and switches in general.

Drparj
08-23-07, 07:56 AM
Those where all the codes that pertained to the door that the obd was reding off, I have another 10-15 codes on other things it gave me as well. I already reset the codes and have disconnected the battery for about 1 minute to see if it would reset anything and still no windows or anything on driver door working. I will try to do switches to get any codes reading again. What if a code says current after it, does that mean it is okay or what?

With that many codes covering practically all of the door switch operations, I would suspect the Driver Door Module (DDM) is at the center of the problem.

The DDM is the interconnect point for all the inputs and feedback signals in the door. You will have to remove the door trim panel to check the security and cleanliness of all the connectors plugged into the DDM; there are five or six (?) connectors.

Best case would be a loose or corroded connector, a corroded switch set, or some obvious wire harness damage. Worst case is probably a failed DDM.

if it is a bad DDM you know what that would cost, I plan to go look at it shortly and take the door apart. There much to taking the panel of or just like any other car?

There are four screws; one at bottom rear corner, one under a plastic trim piece behind the door-open handle, and two behind a flap (velco attached) behind the door-close handle.

Lift the panel up enough to reach one electrical connector and the lock linkage rod clip. If the inner panel has to be removed (and I think it does), the plastic fasteners are the push-in-the-center-pin to release type.

None of the contacts are coroded, they actually look perfect so does the inside of the module. Is there any way to make sure its the module or just assume from all the problems that is the problem. Like I said none of the window switches work on any door. lock switch driver door not work. lock switch passenger door works, back door locks lock but not unlock. memory buttons do not work on driver door but switches do light up. Plus all the codes from above. Anybody every have to replace this module and know a price?

Ok so just talked to Caddy dealer and the module is about $280 and he said it most likely is not plug and play? is this true? He thinks it needs to be programmed by a dealer for the options that are on the car.

Drparj

Okay is there a way to test the driver door module or is there a way the dealer can test before I get one. I did also forget to mention the keyless entry does not work either

When you remove the door trim panel be careful. That one will have hooks on it, when you remove the screws, lift straight up on the door panel, don't pull.
When you lift it will disengage the hooks and the panel will just about fall off in your hands.

I have already done all that. But not sure if it is indeed the door module. Is there a way to check the module. Can I take it to a dealer to check it. Expensive part to not be sure on.

What you need to do before you go replacing parts is test the circuitry going to the module.
Make sure the module has a good power and ground, a good data connection to the other modules on the car and then go from there.
You could have a bad door switch assembly.
If you could have someone connect a scan tool to the car and read some of the data from the door control module you would know more.
It is hard to know from a couple of symptoms and some codes where the problem really lies.
Is there any damage evident on the door switch or connectors? Like overheating fore example.

Do you have any test equipment like test lights or a meter?

Ok I have a light tester and a multimeter and in the works of getting a scantool, but do not have that yet. All contacts on driver module are perfect and all connectors are seated firm. Remember its not just the windows not working it is every button on the driver door. Everyother door lock works but not the window switches. I am going to get the repair manual to figure out the wiring colors to check the positive and ground are flowing into the module. If I do have good power coming in where do I go from there?

Are you still struggling with this DDM several days later?

If you have located the problem, be sure to let us know.

Otherwise, I will examine the schematics (for my '98 Seville) and try to give you some test points to narrow the problem down a little more.

I'll help more as soon as I can.
If this is an emergency... hang up and dial 911.

Okay, just kidding, but if it is urgent you might need to find someone locally to help you.
I'll do what I can but I am pretty busy these days.

No emergency, I can drive with the windows up. I don't have a spec book for testing to see if that is the problem, just let me know how to test it so I don't spend needless money if that is not the problem. Thanks for any help guys

Ok I have a Hayes manual which is good but not great. I have test some wires in the door module and it shows power coming into the window connector on the module, what other wires should I be testing. When I unplug and plug wires in I can hear clicking or relays in the fuse box. I have currently hot wired the driver door window to at least use that, but still nothing else works, no windows at all, only passenger door lock button works, key fob not work, none of anything on driver door work, not window controls, not memory seat function, not mirror controls. Really going insane on this one. Does the Body control module have any link to this system or is it just the door module.

First things first.
Power and ground are the most important things so check them right away, don't limit yourself to just probing the terminals to see if they have power or ground, inspect them to see if they have overheated, bent, or are damaged in any way. The best way is to compare them to eachother, be sure they look uniform. If one is bent or overheated you can tell by looking closely.

Illustration 1 is the schematics for the DDM.
Notice the 2 battery feeds and the two grounds. Find a good test light and carefully probe from a ground terminal to a power terminal, don't jam anything into the terminals to damage them or loosen them or you will create more problems.
If you need help deciphering the pin numbers and connectors let me know.
I am used to reading these schematics so I can tell you what you need to know.
This first schematic is primarily for power and ground testing.

This next one is a little trickier.
In this one we see the driver's door switch, how it gets power and ground from the DDM. Testing this with a test light might work, but it could depend on the light. Long story, but plug the DDM in and then check for power and ground at the respective terminal.

From there you need to unhook both modules and ohm test the wire from the DDS to the DDM called the "SBI". This bus transmits requests for control from the DDS to the DDM, then the messages go out to the respective doors.

If you press the driver's window switch and you hear the relays clicking in the door module then it is likely you have an issue with the DDM.
Since the commands seem to be received by the module, but the outputs are not correct and none of the doors are working this could certainly be the case.

Sorry I have been so slow on this, things are still going crazy.
Let me know what you find.

Me too, guys. I have the same problem. Just bought a 98 sts with 143k miles on it. Runs excellent but the windows dont work. key fob did but now doesnt work either. SO Im waiting for an answer as well.
Good luck.

Now I have the same problem!! I have a 2000 DHS with a dead drivers side door panel. All my other door locks work and my remote entry works. Even the seat warmers still work. NOTHING ELSE WORKS on the door. Weird that my seat warmer would light up and work still on the drivers side but no a damn thing else. I'm thinking faulty module. My cadi is in pristine condition. I took the door panel off to inspect the connectors and everything is like new. Im also thinking that the drivers side mirror defogger isnt working.
Pass side works great. Are all these things connected? HELP!!

I brought my problem to an ex employee for Cadillac and the solution was the contol panel for the power windows becasue he told me it controls the memory function also. He replaced the part and all is worrking now.

I have a 86 deville and I had the same problem with the windows what you need to do is pull the panel off test the motor the switches and put a voltometer on it here is the thread that saved me a lot of money and the guy who helped me on the locks it could be the actuators or a loose ground. See attached linkk for the windows
