I am having issues with all the controls on the steering wheel not working correctly. Turn indicators don't work, radio and cruise control buttons on steering wheel don't work, and only one speed for windshield wipers. I habe been reading about similar issues in other vehicles that this is an issue with the swm. I have tried the quick fixes (replacing fuse, disconnecting battery) and have come to the conclusion i must replace it. Problem is I can't find a schematic for my particular vehicle. Does anyone know where I can find one and if I can just grab the part from the junkyard and install in my vehicle or do I NEED to get it done professionally for programming purposes.

 

The radio and cruise control are likely tied to a bad clockspring for the air bag and related. Are there codes in the systems?

Always best to start with codes.
