The other day I released the seat back with the little lever? on the back to get more room to work inside under the dash. Now the seat back wont latch and stay up. I don't want to tear the seat up as it's a leather covered '99 ElDorado bucket. Is there some way to get to the linkage inside? Thanks. Also, another question pertaining to the Eldorado seats, how do you release the head rest to remove it? Thanks again
