Your out of warranty - does a TSB still apply? But yes I think there is a one. Mine got stuck open too - I had to yank and pull on it has hard as I could to get it closed. It works normally now lol.
You can go to http://www.alldata.com. Create an account - they are one time use its really weird. I just make a funny name like Jack Goff everytime I use it. Then you can have access to have every Service Bulletin for every manufacturer there is. You can only get the TSB# and brief description with the free version however.
No, TSB's still apply. A TSB has nothing to do with a warranty. A TSB is a Technical Service Bulletin that is intended to help technicians fix a common problem that Toyota has already created a solution. In other words, TSB's are normally for common problems that Toyota recognizes as such and offers a set of "instructions" on how to solve said problems.
