Window regulator replacement - alarm goes off

[Kheopsz]

Hi everyone!
My passenger window regulator died last week and we had to buy another one. Bought it and my friend fit it well on saturday, and it works well now.
But, the alarm goes off and on now in a random mode, did a couple of times on Saturday, was quiet on Sunday and did a couple of times on Monday. I turned off the alarm so its quiet now.

There is a chance we forgot something to do? Do we need to teach the new regulator or do something?
Thanks!

As long as the window closes and seals then no, nothing to be done accept learn the fully open and closed positions (wont cause your issue though)
.
Highly likely you've disturbed an underlying issue with the door wiring whilst changing it. Take the look out and check for wiring damage (details in the KB)
