Hi. I want to purchase the two push buttons mounted on the left side of the steering wheel in the parts department and then have the service guys remove the steering wheel and replace the "gummy" buttons with the new ones. This should not take more than 30 minutes tops to the technician. How much do you guys think they will charge me for this? I simply don't want to risk messing with the air bag, or screwing something else. Thanks.

 

Might try this first.

The buttons have a coating that gets sticky over time. Removing the coating is one way of dealing with this problem cheaply.

 

I will try it. Many thanks.
