1999 C230K (202.024) - Can one of you experts please explain the procedure for removing the decorative trim panel piece that surrounds the radio, tempmatic unit, etc.? I need to access the blower switch for repair (fluctuating blower speeds). It looks like the upper vent unit needs to come out to release the trim piece. How? I removed the 2 lower underneath screws but those only released the ashtray unit. I'm careful not to pry for fear of chipping or cracking the plastic trim. Perhaps the picture will better detail my predicament. Your help is greatly appreciated.
