Cleaning the MFS has done the trick for most of us that had the annoying clicking sound but with everything such as the hazards and signals working as a stipulation. Money saver versus replacement of the part since it is expensive. Basically after it is removed you clean it with electrical contact cleaner and apply dielectric silicone contact grease.
Easy to remove. Steering wheel does not need removal. Disconnect battery negative for safety and to disarm the drivers air bag module. Let sit at least 10 minutes before starting the job. Remove the plastic dash bezel (two screws) and disconnect connector to the odometer reset button. This step is needed for clearance to get the upper plastic steering column cover off. Then remove both upper and lower plastic steering column housings. By removing the Torx screws undeneath and separating the two plastic parts. You'll need to do some pulling to get the parts separated. You can leave the bottom cover on the steering column. Remove the top cover completely. Then remove MFS by removing two screws from the top and then the 3 electrical connectors on the back. But be sure to compress the spring loaded horn contact from clock spring assembly and then lift MFS up and out.
IMPORTANT: Installation is reverse but be careful and compress the spring loaded horn contact and make sure it seats properly on the clock spring before tightening down the MFS otherwise you will have a mess on your hands. Good luck.
