What is the deal with this recall/TSB?

I had my local dealer run OASIS on my car before I purchased it and that was the only thing not done...

The defrost vent was loose, but I pushed it back in and everything looks just fine... it has sat on a lot for the past several weeks (10-12 weeks) in blazing heat and the dash looks ok to me... the car was built in 12/98 as a '99 model year...

are there any pics showing what actually happens to the dash?

btw I am glad to see that Jim is still here!
