Well, the problem actually sounds like the onboard computer had an issue. This can happen if the battery has low voltage output. This is sometimes seen in vehicles that have a sluggish start or have had to be jump started recently. The steering, gear selector, power windows, mirrors, wipers, etc won't work and it all happens at once. Disconnecting the battery resets the computer and solves the issue. In theory, it could have been solved by the disconnection of the battery to replace stuff and have had nothing to do with the replaced parts. Lots of info on the Google about it.
