Shimano 105 RH Shifter Malfunction

My first post on the road forum.

I picked up a Giant Defy Advanced 2 last year with a 105 group set. Very pleased and everything has been fine.

I was out the other day and went to change to the smaller sprockets using the 'inner' lever and nothing happened. I was suddenly aware that the whole lever mechanism (including the brake lever) was not where sit should be and I was able to give it a nudge and push it all to the right and everything worked fine. However every time I went up to the larger sprockets (using the full mechanism), although the shift was fine, the lever would not return and was sticking.

I have had the hood off and flushed it thoroughly with GT85 etc but to no avail. It works fine if I push the lever back but kind of defies the point! Any ideas or are its days numbered?

    Have you checked the cable is seated properly? I'd probably release it from the RD and check it's not fraying in the lever.
