Beginning a couple weeks ago I've had a consistent problem where while driving something under my steering wheel will buzz, the chime that goes off when you leave the car goes off, and none of the windows (sunroof included) work. There isn't anything that I can see influencing it (ex bumps in the road or hard turns) and it will happen for a minute or two and then everything goes back to normal. The only thing I've seen affected are the windows and my tolerance level for this problem. I don't really know where to even start with that, thought it was maybe something to do with my spark plug wires going bad but it hasn't gone away after I replaced those. Has anyone else had this issue? How did you go about problem solving it? The beeping and not being able to move my windows are getting on my nerves lol

 

Driver side wire harness in the door sill is probably chewed up or, if youre lowered, you might have chewed through the fender harness on the driver side. Check both but one of those is the likely culprit.

 

Both are possible, I'll have to check that out then. Any particular wires to keep an eye out for or just whatever is broken? I actually just had the front end of the car torn apart for the headlights and double checked that the harness in the wheel well was good as I am on Teins (it was) so that leaves the door panel. Which kinda makes sense I guess.

 

Its not so much a door panel rather than the door sill. There is a rubber boot that houses the wires going from the door into the engine bay. over the years the boot will get worn through because of rubbing and then eventually so will the wires. Simply opening the door and inspecting the boot will tell you if there is an issue there. In my case it was the ground wire on my 95 sc300

 

That's generally true, but I've seen wires fail inside the boot with no visual wear to the boot itself. The wires are flexing every time the door is opened and closed, and like any piece of metal, repeated flexing eventually weakens it to the point of failure. Well, other than maybe exotics like titanium that are designed to handle it.

From the OP's description, I also wonder if the mirror/seat/whatever ECU up under the dash could be to blame?
