2001 Volvo S80 Repair Question
I think I have a blown fuse but having a problem tracking it down.
For the sunroof, check fuse # C34 in passenger compartment fuse box.
The doors not unlocking could be due to a wiring or switch problem. Did you try using the passenger door to lock and unlock to test if it works?
As to the remote, diagnostics are required to find the cause.
Trouble codes for all these could be stored in the control modules and the first thing you need to do is to get a scan done to find if anything is recorded.
