'95 E320 wagon headrest problem
Is there a fuse that the headrests are linked to? All of a sudden, they stopped working! I miss 'em. Need 'em to work again. Help :)

Ultimately there is, not sure which one or where, I think all the seat functions would quit, not just the headrests, if you blew the fuse.
Has anyone removed the headrests lately, like to install a seat cover? You yank the headrests out, then have to make sure they engage back into the little transmissions that move them up and down. The motors are either in the backrest or just below the seats. Do you hear them running? Are they stuck in the up or down position? What usually works, if the motors run, is to run then to the raised position, then push the headrest down rather quickly and they will snap back into place. Gilly |

This isn't a solution, but may lead me to follow this thread:
Does it work with some assistance? That's exactly how mine behave. They stopped working, but if you help it along it does move with the motor...it just needs a little help. Maybe the motor has become tired. Signs of it about to go out. |

I read someplace that it does harm to the mechanism to force-ably move them. Seems possible. |
while we are on the head rest subject,my drivers side goes up and down freely,but the passengers head rest only goes up,i have to push it down manually,do you think the motor is weak or off track?

From what I've heard there is a small plastic gear inside the motor/transmission that tends to break with age and use. I believe you can gain access to assess what might be the problem by removing the rear seat back panel. There should be a few threads on what to look for and how to correct it if you do a search.

Mlozzi, no in your case, that sounds like the headrest is not snapped in to the transmission, raise the headrest and push down on it to snap it back in.
85 Dsel, I can try to look at a schematic later, very odd both sides would stop working at the same time, jst about to head out to work now. |

Fuse "E", but that covers everything else in the seat as well, so not sure this is the answer. There is also a common ground for both seats, but again this is for all the functions, not just the headrest. If you want to get one of the switches loose I'd recommend diagnosing one and see if you can get to the bottom of it that way. There are 2 wires running to the headrest motor, a pink with green stripe and the other is just pink, you could try jumping B+ and ground to these wires and see if you can get it to move that way.
Does the car have memory seats? Gilly |

No memory seats. Thanks... |
You would find the wires under the seat, then one of 2 things. Using a car battery you could jump power and ground to the wires going in to the motor to see if it will work with an independent power source (the battery), OR you could just test the wires as they are to see if you are getting power and ground to the motor. Again I don't see any one thing that would fail that would kill both headrest motors at the same time, so it may be some odd coincidence that they both died at once. The only things common I see for them both would be taking out all the seat functions, not just the headrests.

Thank you for your interest and time in this matter...:) |
And not to have you throw good money at a problem, but the usual suspect is the switch itself, in the door, which is the "whole" seat switch assembly, not just the headrest switch.

You might try some switch cleaner first. They reside at the top there, and can get dirty easier. Not to expensive at the auto parts house.

Not too bad, usually the door panel can stay in place. The small "knobs" that look like the seat cushions (that you move to make the seat move) pull off. One one of them (the one to move the entire seat fore/aft) there is a plastic C clip you take off, then the cover over the switch can be taken off. After that there are a couple screws you can barely see on 2 corners of the switch, you remove those and the switch should come out of the hole in the door panel. I might be able to post a copy of the work instructions if you think you want to try it sometime.

:::UPDATE:::
I have to eat a little crow here guys! (When I had previously messed with this issue, it must have been that there was just enough ambient noise that I couldn't hear the motor running thus assuming they weren't!)
Early in this thread I was asked if I can hear them running, I replied "No". Well....a little while ago I went out to the ::QUIET:: garage and manipulated the headrest button and to my 'HORROR' - I could hear the motor running! :eek: This was the case on both headrests. Sounds like they are off track or the link that moves them up/down is broken/separated. No? :confused: |
There are some little plastic things in there that have a tendency to break on the headrests. On the passenger side of my 300e it wouldn't work. They took the panel off & glued it, and I never had any trouble after that. You might just be off of track too! Probably want to check that first.
|
Right, just take off the cover on the rear of the seat and look it over, might need a helper to run the headrest switch while you look. IIRC the motor is under the seat, a metal cable inside a plastic outer sheath spins and makes the headrest move.
|
Thanks Guys!
I'll search here for a thread I came across a while ago about removing the back of the seat. Seems there were some issues and challenges I need to be aware of. Don't want to tear the upholstery :eek: |
