It sounds like you can hear it release but it only raises 1/4 inch or so - if so it is the strutsI just purchased a 2006 SSR and the rear deck lid does not pop up when activated. Is the problem the struts? When you lift the lid it stays up by itself.
Mikes struts (simple engineering) work great. I replaced the lid and top struts. Everything works great and my top does not fall when it close to the bottom. Opens and closes smoothly.If you try the Advanced Search in the Tools drop down (red bar above) there is lots of information about this but the simple answer is the struts are probably bad and need to be replaced. Replacements from simple-engineering.com will out perform the originals. GM direct replacements will probably not do much better than current.
