Window comes down on its own WTF.........

[amartz]

Hmmm, I can get a used switch removed from a 2012 for $47.84, or a New in box for $99.88, both on Ebay.

 

[AVMIII]

I'd probably spring for the new one, just to be sure that it has not seen any water damage.

 

[amartz]

That's what I was thinking also!

Well, I got in the new switch, after USPS sat on it in Jax for a week. Unfortunately it wasn't the exact same switch, 93570-3M623PB2, instead of the 93570-3M613PB2. That 623 instead of 613 means that the door locks don't work with the remote. When I put the 613 back in, then the door locks are fine.

So I just sent an email to the vendor, asking to exchange the switch for the correct one.

oh geez what a pita. good luck on the ultimate quest!

Has anyone have a problem with their Genesis window coming down on its own when it rains or while going through the car wash, a friend of mines has a 2009 4.6 Genesis and everytime he goes through the car wash his rear passenger side window goes all the way down , needless to say inside the back gets completely drenched & Hyundia doesnt seem to know how to fix it

First, seal up the window motor connectors with “permeatex”, auto parts stores carry this. Second, check the rubber seals around the window, and see if they are cracked. If so, seal them also with permatex. Third, to get the window back up, start the car, open the back door, and slam it as hard as you can. The window will go right up. Check the chrome fitting around the back window, and seal it, if it has separated slightly. It only takes 1 drop of water on the window motor.

I finally got around to taking my driver door panel off. It wasn't as bad as I thought it might be. Found an online video where a mechanic stepped thru it. Then I took a can of Lithium Dielectric Grease, and popped open all the electrical connectors, and loaded them up, and put them back together.

One of the things I noticed is there are 2 wires coming in thru grommets from the outside side mirrors. The grommets didn't seem particularly tight around the wires, insulated with a fiber weave cover where they go thru. So I pumped in a bunch of the lithium grease around the grommets, thinking this might be where water is sneaking in. Looking at how water could run down the wires into the top of a connector just below the mirror, I also loaded up the top of the connector with grease, where the wires go into the connector. And then put it all back together.

The point of the whole exercise was to water-proof the wiring. I then took it to a local no-touch car wash where the strong-pressure water was almost guaranteed to make one of the back windows roll down, in the car wash. So I went thru with the mirrors folded in (which always caused the problem), and this time had no issues. I'm pretty sure this confirms my suspicion that it is a water related issue getting into the wiring. Like whenever it rains hard, or certain car-washes. I'll let 'yall know if this holds as a permanent fix or not.

Keep us posted

It's setting in my garage right now, even though it's raining, because, I just washed it!! ;-)

But yesterday was the first time I'd been able to take the Genny thru this wash in a long time and have the back windows stay up. So, for the moment at least, I'm happy!

If you need, I could probably find the links on removing the door panels I found. It was a lot easier than I expected.

Looks like 3 screws.

Well, I'm cautiously optimistic. I left the Genny sit outside in the rain during the day where I could keep an eye on it in case one of the rear windows rolled itself down. It wasn't a gully-washer, we had about 0.5 inch of steady rain. But it sat out in it about 5 hours, and the windows stayed up!

Well as I have said elsewhere in this thread my car's issue was with the master door switch assembly. Yes a rear window and even the front passenger window would sporadically go down. But once I replaced that entire assembly the issue stopped.
In my case at least it was only this switch and not water leaking into the door. The water had leaked onto the door switch when I occasionally drove with the driver's door window open and some drips fell in, and directly onto the drivers door switch.

I'm pretty sure that was not my issue. But water getting in the circuitry would have produced the same effect. I had tried replacing the switch, but they couldn't match exactly the part number, and it didn't work right, and I had to return it. But regardless, I could cause the problem with a car wash even with the door master switch up and out of the arm-rest (still connected), where there wasn't a chance of water actually getting in the switch. And it wasn't driving with the window down while it was raining, which I don't do.

What I believe to be the cause of my issue is the two wires going thru a grommet to the side view mirror. I say this for two reasons, 1) the problem was worse if I had the side mirrors folded in, and 2) the problem started immediately after I needed some body work done to the drivers door, after somebody backed into it in a parking lot. I even had the body shop pull the door apart looking for issues, and everything seemed dry, at the time. But then, the problem would go away a couple hours or so after getting wet, as things dried out.

When I was hitting everything with the dielectric lithium grease, I paid particular attention to the grommets the side mirror wires go thru, and the harness connector that is directly below those grommets. It did seem to me that the fit around the wires was a little loose, and could pass some water thru onto the inside connectors. The body shop probably left the side mirror dangle as they worked on the door, and I'm thinking that may have stretched the grommet.

Regardless, so far, so good. Now I just need a big rain-storm during the day where I can watch it.

amartz,
I hope that all the work that you've done solved your particular and may I say someone unique problem. I don't drive in the rain with the window open. But if there happens to be any water on the roof from, say condensation overnight, dew, etc, the water will drip exactly into the drivers door switch if the window is even slightly open.

2013 Genesis sedan, I have always gone though automatic car washes and for seven years I never had any issues, until after I had the driver side front window replaced.. first time it happened was when I had gone though the same car wash that I had always used in the past, and the left rear window automatedly started to go down just as I had gotten to the blow dryer and I it wouldn't go back up...(wtf) got home put in the garage overnight ,the next morning when I started the car the window automatedly went back up on its own. Second time it happened, the car was parked in the driveway and overnight we had a heavy rain storm, and when I looked outside I saw that both rear windows had gone all the way down(wtf again). Car was not running just sitting in the driveway when this happened and the windows would not go back up until after I put it in the garage for a few hours again. Since this didn't start happening until after the window had been replaced, I assumed that had to be the problem. So when I inspected the window I noticed that there was a gap between the window and outside window seal, where when it rained the water steeped inside the door and must have caused a short of some kind.. To test I put clear packing tape crossed the entire window seal and then drove thru the car wash and nothing happened, so I wait a couple of hours and tried again and all was good... I ordered and replaced the window seal and everything is back to normal..

Exactly the kind of symptoms I experienced. I'm convinced it's water getting into the wiring harness, however that happens, and causing problems with the door module that talks to the rest of the car.

I don't think I have any gaps with the outside window seal. Was this at the top or the bottom of the window when it's rolled up? So I can double-check.

It was the outside bottom weatherstrip .. all of the other window's bottom weatherstrips had full contact with the windows from front to back when they were rolled up .Only my front driver side window didn't have full contact with the bottom outside weatherstrip when rolled up, which would let water trickle down the space that wasn't in full contact with the window and cause a short of some kind in the main window module. I would suggest that you take a look at all of your windows and make sure that they have full contact with the bottom weatherstrips when they're rolled up.. My issue was with the front driver's side window, but it may be possible for any window with the bottom weatherstrip not completely in contact with the window when rolled up may cause the same problems.

But it sat out in it about 5 hours, and the windows stayed up!

Wow, that's commitment. I would have watched occasionally from a window.

I didn't say *I* stayed out in the rain with it!!
