I have a 2004 clk 320. I think there's a cassette in the player but it won't play and the eject button does not open it. Sometimes when I press Tape it says 'No Tape'. Other times it will say "Side 1".

Anyone know how to fix this?

It may be a sticky switch that tells the player that a tape is installed. A search of the forum with terms such as "cassette won't eject" or similar terms may get you an answer.
