Hi guys, I found quite a few posts about windows, but didn't see any problems like this. Here's what happened: I took out the driver seat so I could have a better look up in the footwell to see if it's possible to replace the clutch cable without removing the dash. I had to unplug the seat from the cable coming out of the floor before I could remove the seat completely. I also had to put the roof down because my feet were up in the air while my head was under there. When I was finished, without concluding anything, I put everything back. I noticed the seatbelt warning light was flashing even though I was sitting there. Worse, when I put the roof back up, none of the windows would go up. Just nothing at all happened when I pushed the switches. There's never been any sort of trouble with the windows. I considered the coincidence of the seat belt light flashing, and took the seat out again. Yes, it was plugged in, so I unplugged it and shorted the plug with a little U-shaped wire. The seat belt light stopped blinking. I didn't think that should have anything to do with the windows, anyway, so I next put the roof up and down a couple of times, and still the windows wouldn't work. The red roof light went out after the latches were fastened, and it went beep, just as it should. But no windows. The last thing I could think of was resetting the ecu(s) so I disconnected the battery for about 15 minutes. When I put it back, nothing had changed except the radio forgetting all its stations. I'm pretty sure this is something simple, but I'm a bit mystified. Anybody here had something like this happen? This is a problem, because it's still winter; the days are getting nice, but it's cold at night. And, of course, when I park the car, it's not very secure. Or weatherproof. Before anybody suggests it might be the battery, I replaced the battery with a LiFePo4 and a capacitor bank. The roof goes up and down without the engine running, just fine. Not the battery. I'm not sure what to do next. I'm also not sure if the windows have their own ecu or it they are part of the roof one. What I do know is that I have to go into the city tomorrow and leave the car at the train station with all its windows open. I'm not liking that. Edit: Well, do I feel stupid, or what? There is a switch on the right side of the dash, between the fog light and the rear window heater switches, that disables the windows if you push it. During my adventure in the footwell, I obviously pushed it. I think this switch might not exist on Copens in other countries, only Australia. I have never had occasion to use this switch, and had lost any awareness of it that I might have ever had. It was only while staring at the wiring diagram in the Workshop Manual (yes, the windows do have their own ecu), that I spotted the switch, whereupon the light bulb went on. I went out to the car, and sure enough, that was it. I considered deleting this whole thread, but decided to leave it, in case someone else has the same lapse.
