airbag light

hello

I changed my passenger front window regulator and had the ignition on while doing it because you need to drive it to the correct height in order to get the lock pins out ,totally forgot to switch it off while I removed all the plugs including the airbag module that is in the door ,

I now have airbag light on , the light goes out but comes right back on again

so is it because of leaving the ignition on or the second hand regulator that I have fitted was faulty?

any ideas guys
