Because access varies slightly depending on the specific engine (2.0L, 2.5L, or perhaps even a V6 were options), you'll need to consult a repair manual specific to your 1997 Chrysler Sebring convertible's engine. A Chilton's or Haynes manual will have diagrams and detailed instructions showing the starter and its solenoid's location. Searching online for "[Your Engine Size] 1997 Chrysler Sebring Convertible Starter Location" might also reveal helpful images from forums or repair sites.
Trying to locate it without a visual aid is difficult, as other components are close by, and there's a risk of accidental damage if you're unsure of the location.
