Hi, this is my first post, my names Alex. I'm from Mesquite, TX.
I actually used to work as a technician at an Infiniti dealership. I went to a car tech school, did exceedingly well, got a great job with Sewell dealerships in Dallas.

I'll try to help with any problems, didn't see if there were any techs here.

Anyway, I don't work at Infiniti anymore, but I do own a Black 2004 G35 Sedan with the 6 speed. Got it in June of '09. Fun car...

I've never seen a problem like this, so hopefully someone here might have some insight on what the deal is.

I had the car for about 2 or 3 months when the problem started. When I turned off the car with the windows rolled up, I opened my door and all four windows rolled down simultaneously.
As soon as I turned the car back on "Acc" or "on" I was able to roll up my windows and as soon as I turned the car off again and opened the doors, they all rolled right back down in unison.

To fix this I rolled my windows up, disassembled the door panel and unplugged the window switch to take away power from the windows. But now I can't roll my windows down, which sucks.
Especially after 6 months.

It started suddenly, and has not got worse or better.

I have tried the factory reset procedure for the window height and safety mechanism.
Didn't do anything, same problem.

This has led me to believe it's probably the window switch, but I don't want to be hasty because I don't really have the money for it.

Well, I hope someone has encountered this before, I sure would appreciate the help.

 

so you use to be a tech? and you are asking us about this weird problem?

what controls window's power/ground operations aside from the main switch? BCM? maybe a bad BCM relay?

 

Never experienced this, but stuck "unlock" button on one of your key fobs perhaps?

 

Whats the factory reset procedure for window height and safety mechanism?

 

I've solved the problem, I figured the problem was in the main window control switch. It was my best guess, so I replaced it with a used part off of Ebay. All the windows now work fine.

I don't have internet at my house, but when I do I'll post the reset procedure.
