Strange things happening to my S80 after installing a new battery - Help!

Two weeks ago I had Walmart put in a new battery in my S80-T6. They
did exactly as the manual instructed them to do by waiting ten minutes
with everything turned off before disconnecting the battery. They
disconnected the + and the - in the order the manual said. Everything
worked great for a week. Then the indicators stopped working. The
right front window wouldn't go up or down. I couldn't change the radio
channel from the steering wheel.

I thought it was a fuse and checked all fuses under the hood and in
the car. Then I simply disconnected the battery and reconnected it.
All was fixed ...... until last night. Now the strange weird stuff has
begun again. If I disconnect the battery again I'm sure it will be
fixed for awhile anyway ..... but that's a pain.

Any suggestions would be greatly appreciated. Could it be that Walmart
installed the wrong battery in my car? I have no clue what is causing
this and I'm hoping not to fork out $200 to Volvo to tell me.

Thanks,
Don
 
Try this first.
Remove both pos and negative cables from the battery.
Touch both bare cable ends together for 5 seconds.
This will discharge any stored temp memory in all of the
of the brains. Re-connect the battery cables.
If the problem returns is sounds like the SWM or
Steering Wheel Module might be faulty.
Probably nothing that installing a new battery caused.
The 1999 and 2000 models have an update for the SWM.
The SWM may also need to be replaced.

Interesting. If I replace the SWM are you saying that fixes the
indicators, the electric windows and all the other stuff? I think you
read only part of my post. Try again.
