Hey guys new member here, I've had my xc90 for about a year now without much issues. I do all of my own work and just recently replaced my haldex pump, the pump was indeed bad. To my surprise though it didn't fix the issue and now I have many other multiple issues. I let my battery get low and I don't know if this contributed to the issue or no but I have charged it up by the car (it started on its own power). To start my central locking will not work, or my interior lights when I open the doors (work when I push the button) no running lights, rear door windows do not work and my awd.
I tested at the rem for my awd and no power if I apply power I do get my awd back, this made me assume the rem but all of the other circuits that don't work have power to them (also my brake lights work). I have checked all fuses and they seem to be good the only one I found bad was an inline fuse for my trailer lights that are after market, I replaced the fuse but no luck. I also removed the wiring completely and still no luck. I'm confused on where to look with out having a vida/dice. Looking for any hints or places to look? Ground? I think it's coincidence that it happened the same time I replaced my haldex pump.

Did you try to disconnect battery? But, put and turn key to second position before connect battery.

Yes, I did. I'm trying to get a dice set up to investigate further.
