I have to replace my GM Combination switch in my car. Its the switch in the steering column that has the wipers high beam turn signals etc. I have removed the bottom trim cover on the steering column but the top one will not budge. I really don't want to break it but no matter which direction I try to move it it just doesn't even want to move. It is really hard to see inside of the trim to look for screws but there are none that I can see.

You need to be real careful working around the Airbag. It has explosive force.
