No turn signals,no use of remote to adjust stereo and one speed on wipers on 2005 Volvo S60

Dealership cannot locate issue. Suggested I have all connections cleaned for $650.00 aand no guarantee that would work. Can anyone help with this? The turn signal was replaced as well as the solenoid a few month back. They check that and said it was functioning properly.

Sounds like there is an issue with the Steering Wheel Module (SWM). This is what controls all of these items. Is the problem occurring all the time of intermittently?
