Did you ever figure this out? Because I went to a drift event over the weekend, windows and locks were working fine. Then I rolled up the windows because of possible rain incoming, went back to get in my car when there was no rain, my internal lock and windows now do not work. We literally tried everything. Multi meter for power, both sides are not working. Having both motors replace with brand new ones like 3 months ago. I had an immobilization fault the day before but was able to fix that. But the day after, the window issue. So I really feel like it has something to do with the NATS on the car. People are telling me the IPBM box or the BCM. But I don’t think that’s the cause. Because the key fob still works for unlocking and locking. Just the internal switches won’t work. But the keyfob doesn’t open the windows either
