Power Window/Lock

maybe it's just a freaky coincidence? you could check wiring between door hinge. and ***** probe it for voltage.

It seems pretty cause and effect. Could it have shorted something in the process of installing the new battery?

for just 1 door? seems unlikely. seems we are stuck between the seems? the bleeped word is p r i c k. but when you say rear door you mean side door?

Yes. Right rear side door.

1 fuse for all doors, right?

Multiple Fuses, one for each of the doors

did you check fuse for power?

Negative.

does fuse have power?

Your rear door module could have fallen asleep on you? Try this first. Disconnect both battery cables and touch the cables together and leave it like that for 5 minutes. Reconnect the cables and see if the module wakes up and starts to operate normally? If it does not, remove the door panel and check for power and connector pin #18 Black wire. If there is no power check fuse #63 (20A)at the CEM under the front passenger side and make sure you have power going through that fuse? If no power is going through the fuse then check fuse #3 (60A) in the engine compartment. From here if everything seems OK you will need to take it in to Volvo to have them scan all the control modules to make sure that one has not gone offline? If it needs replacing software will most likely need to be downloaded to the replacement part? But do this check first and let us know what you find?
