BMW iX3 Power Window Failure: EV Owner Seeks Solutions

I dealt with a similar issue on my 2019 BMW i3s just last month. The power windows completely stopped responding, and initially, I also thought it was the window regulator. Took it to the garage, and turns out it was actually a defective master power window switch in the driver's door. The technician explained that moisture had gotten into the switch assembly, causing corrosion on the contacts. This is apparently not uncommon in these electric BMWs. The repair was straightforward but needed specialized diagnostic equipment since it's connected to the car's electrical system. They had to reprogram the window control module after replacing the switch assembly. Wasn't a serious mechanical issue, but definitely needed proper BMW-certified expertise. Based on your symptoms, it sounds very similar to what I experienced. Make sure whoever works on it has experience with electric BMWs, these aren't like conventional cars where any mechanic can dive in. The electrical systems are quite complex and interconnected.

Thanks for sharing your experience! That's super helpful. Had a feeling it might be something electrical rather than mechanical. Just wondering, do you remember roughly how much the switch replacement and reprogramming set you back? Also, has everything been working smoothly since the repair, or have you noticed any other quirks?

Hey there! Happy to give you an update on my BMW i3s window situation. After getting it fixed, I can confirm it was indeed just like I suspected, the master power window switch was the culprit. The total repair came to 200 € for both the switch replacement and the reprogramming work. I know that might sound a bit steep for a switch, but considering the specialized work involved, I think it was worth it. And the great news is that since the repair, everything's been working perfectly! No more window issues at all. The technician did a fantastic job, and it's such a relief not having to deal with those frustrating window problems anymore. You know how annoying it can be when something as basic as your windows aren't working right! Just keeps reminding me how important it is to get these electric BMWs serviced by people who really know what they're doing with the electrical systems. Best decision I made was going to a proper BMW specialist for this one.

Thanks for all the details! Finally got my iX3 fixed yesterday and thought I'd share what happened. Turns out my issue was slightly different, it was a faulty door control module, not just the switch. The mechanic I found was great, really knew his stuff about electric BMWs. The repair took about three hours and cost more than your switch replacement, around 450 € with parts and labor. But honestly, after the headache of dealing with non-working windows, I'm just glad it's sorted. The mechanic even showed me exactly what was wrong and explained everything clearly. Everything's working perfectly now, all windows go up and down smoothly, and no more error codes on the dashboard. What a relief! Thanks again for helping me understand what I might be dealing with. You were right about needing someone who specializes in electric BMWs, definitely made a huge difference. Think I've finally found a reliable mechanic for future issues. Nice to know there are still good ones out there who know what they're doing with these high-tech cars!
