my horn and steering wheel function buttons have stopped working
All of the sudden my horn and functions buttons on my steering wheel have stopped working. What could it be? A fuse? How do I know which one?
This sucks! Thanks.

You can check f29 @ interior fuse box (driver side, side dash) and f64 @ front SAM (driver side, rear engine compartment). You should have dealer or independent check for stored fault codes (i.e.: 9325 and/or 9340) Steering Column Module may need replacement. If you decide on DIY I can forward WIS to replace however, requires STAR initial startup (part # 1715451432 for comparison shopping, parts.com $120.75).

Did it fix your problem?
I asked a merc mechanic what's the craziest thing he's seen and he said that a customer's horn didnt work and the problem was the speedometer needed to be replaced. Hope this isnt your issue.
