You need to remove the Interior door panel. From there you can gain access to the speaker and replace it as needed.
6.5'' Front 6.5'' Rear IIRC
on my 95 SL1 the plastic screen over the speaker just pops off with a screwdriver. dont take the door apart if you don't have to.
5 1/4 i think
5 1/2 inch
There are two screws on the the door panel.
My 2007 cobalt also has this problem. The chimes and turn signal sounds come out of the speaker in the drivers door. If there is a bad speaker connection, or the speaker no longer works, you won't hear any chimes.
Open The Door, Remove The Door Panel, Remove Speaker, Wire The New Speaker, Fix The Speaker To The Door, Refix Door Panel, Switch On
