1992 300CE w124 - rear head rest won't lock up
 

can someone help me with why one of my rear headrests won't lock up?
thanks

could be a vacuum problem.

You may have to pull the rear seats out to check to see if there is a disconnected vacuum line.

well one of the headrests works fine..the other one won't stay up...is that still a vacuum problem?
i thought the vacuum prob was when they stayed up and didn't go down?.....
doh...
i'll look into pulling that seat out...now just to figure out how....ugh

seat is easy. there is a switch on the bottom custion . you push it and pift out the cusion.

Then there are a couple of bolts I believe holding the backrest on. you undo those. Pull out the headrests. they should just come out I believe.

Left the rear panel to gett he hooks at the top out and it should come out.

Then you have access to the headrest locks.

Perhaps the one is sticking or something. Otherwise a vacuum leak could have stopped it from closing the lock somehow. who knows. Best to gte in there and check it anyway, maybe lubricate the mechanism.

I'm thinking vacuum or something is disconnected or frozen
