2017 440i Convert Roof Pump Issues

[RainX]

Hi All

I am hoping someone can help.

Cut a long story short, my roof is not working due to a water leak. I have replaced the salmon relays on the pump, and also checked the control unit which appears fine. The old salmon relays were a mess!
I have put everything back together but whenever I press the roof switch the windows dont lower. I can hear the relays clicking and a short buzz which sounds like the pump but nothing else happens. I have checked fuses 142 and 143 and they look fine, however removing them didn't appear to make any difference. I removed one of the relays and no noise at all.

I am a bit concerned about the windows not coming down as before I replaced the relays they worked.
All I see on the dashboard is an orange convertible roof icon when I am operating the switch which I think normally comes on when it is operating correctly. I dont see any warning errors like I did previously. seems as though the relays have fixed something but something else is not right.

Any help appreciated.

Thanks
