electrical problems!!

[gxp937]

Hey everyone. I replaced my driver door module thinking it would fix my driver door issues. I bought a new one from the DEALER!! And still none of my driver door controls. still don't work!!! Can somebody help me please. I checked the fuse which was good and I had the harness tested that the module plugs into and still no luck.

There have been numerous threads posted about door problems. Have you searched and read through any of them? Is this a new problem, or have you posted this before? I don't recall seeing a thread from you but I may have missed it. If you have, post a link to the thread so we can read the history, otherwise you'll need to document exactly what is going on before we can be of any help. There are a few possibilities and more details are needed.

I'm pretty sure his controls stopped working when he picked his car up from the tint shop.

If this is the case, my first thought is they didn't plug the driver side switch console back in. Most people don't realize you don't need to remove this in order to take the door panel off. The common thought is to remove it and look for the screws holding the panel to the door. I had my car into a GM dealership and even they managed to get it wrong.

Hopefully he'll chime in and confirm the problem. Thanks for the heads-up.

I haven't read any prior threads on the problem I am having. I took it back to the place that did my tint(after which it stopped working). And they said they never took the door panel off! plus their argument was they did the same procedure to the other three doors!! anyway I had someone test the leads to my connections leading to driver module and they all read positive!! So what else is there to do?

[ddalder]

I've seen too many shops try to dodge responsibility. They didn't take the door panel off??? I find that surprising. Any quality shop would need to in order to get the tint far enough down on the glass so there wasn't a clear line at the bottom.

The first thing I would check, based on what I've read so far, is the master control switch on the drivers door. There is a spring steel clip that holds it in place. Slide a small screwdriver under the end of the switch assembly (closest to the window lockout switch). This will allow you to press the clip in and lift it out of the door. There is a single black connector that plugs into the bottom. It will be a 10 cavity connector.

A few other questions, should this not be the problem...

Do the windows and locks on any of the doors work?
Did you check the fuses for each door module? There is a seperate fuse for the module in each of the four doors.
Does your remote keyfob work to lock/unlock the doors?

[ddalder]

I had some additional thoughts on this... When you say the driver door modules was replaced, are you talking about the switches or a black module that bolts onto the door behind the door panel and has four connectors that plug into it?

In addition to the questions in my last post, do you have sound from the speakers in the drivers door?

[gxp937]

I replaced the black module bolted onto the door. Yes all the locks and other switches on the other doors work. I just can't control them from the driver door. I still get sound from my door speakers, and yes my keyfob still locks and unlocks the doors. I pulled the fuse to the driver door to make sure its working properly. Which it does. And all my lights on the door even light up when I turn my lights on!! I don't know what else it could be!!???

Sounds like your switch panel died. Find another one, and swap it in, and see if that solves the problem.

Ed, before you send him to spend money on one of these, it would be helpful to know if he actually confirmed what I suggested earlier. He hasn't posted that he removed his existing one and checked the connection yet.

gxp937 - Did you do this yet? Also, even if it "looks" like it's plugged in, unplug it and make sure there's no bent pins on the bottom of the switch module. I'm still not convinced the tint shop didn't have this out.

[00Beast]

Well, what I meant by "Find another one and swap it in" is to see if he knew someone who's he could swap in for a few minutes to see if it fixed the problem. Sorry if I wasn't clear in my post.

[gxp937]

I checked and made sure that the master switch was plugged in. I even cleaned it to make sure. Still nothing. Why would the window switch keep the door lock and memory seat controls not to work??

[00Beast]

Oh, I didn't realize your memory and lock didn't work, either. Unless they're powered through the master panel, and your module works, I can't see how it's not working.

[ddalder]

That would have been helpful to post. I will have to look through some diagrams but I'm away at work for the next couple of days. I have a couple of thoughts, but before I post I need to confirm what I'm thinking.

Have you had ANY other work done to the vehicle recently, other than tint? Also, have you ever had this same problem occur intermittently in the past?

If you haven't already, you may want to remove the trim from around the door handle and make the same inspection of the connector that plugs into both the power lock switch and the memory switch cluster. Check for bent pins, etc. This isn't my first consideration, but should be ruled out none the less.

When you had the door panel off to replace the module, do you remember having to release a lever on the connector where your door panel plugs into the door wiring harness or did the connector just plug in and out? I'm wondering if the Lever Lock connector may not have been locked together correctly. I think before spending any more money on parts, all connections have to be thoroughly checked. It's not a fuse/power issue because of information you've already provided, but I'm still suspicious this may be a connection more so than a defective part.

The connector I'm talking about looks similar to this one, only black in colour:

[gxp937]

No I haven't had any additional work done to my car except for upgrading my interior speakers. But I done that after I got my tint done. I made sure the blue clamp was in its lock position for a good connection. But before my door controls stopped working. A couple of times prior to me getting my tint done. As soon as I got in my car, turn the key to on the driver seat would move back and forth sporadically and the lights on the driver door would flicker. It would stop on its own though. Then it did it again when it came time for me to roll my windows down. Thats when my driver door controls quit all together.

[ddalder]

Okay, in order to sort this out ALL the pertinent information is important. I sounds to me like you were in fact having some intermittent problems before the tint was done. Read through this and tell me if it's accurate and in correct chronological order.

1. Your car had been working fine, no problems at all.
2. Your seats started to intermittently adjust themselves and the lights on the door would flash when you turned your key ON. At this time your other door functions still worked. (Specifically which lights would flicker?)
3. You had the tint installed and afterwards your driver door controls would not work at all.
4. You upgraded your speakers. When you did this, your driver controls were already not functioning.
5. You replaced the driver door module and there was no change. Still nothing works.
6. You checked all the things I asked you to look at and all those checks turned up no problems.

Is this correct? Think about everything carefully and don't leave out any more information. Based on your last post I likely would have started troubleshooting elsewhere. You need to be clear, accurate and specific.

[gxp937]

yes everything you said is correct. The lights that were flickering on my door was the main window switch control and the memory seat lights.

Does your driver door speaker work?

Sounds to me like the black box inside the door went bad or something, and not the switch module.

He already posted that it was replaced with a brand new one from the dealer. No change.

[lewis26]

Oops, read too quickly!

Maybe an electrical short? I don't have memory seats, but are those tied into the door module, or switch module?
