Manual over ride on electrical seat

[Frazerb]

Morning,

Completely stuck with a seat problem. My car has been badly damaged by water as it sat for over 6 years so much so that most of the electrical motors on the seat are not working. I have tried everything to get them moving but as yet no success. I acutally think it is the switches that are knackered not the motors but as they are closed units it is hard to diagnose them.

Does anyone have any ideas on how to even move the motors manually. The driver seat rear motor is stuck in the fully up position - ideally I would like this a bit lower - the rest I can live with.

Any help appreciated,

Many thanks,

Frazer

If I remember correctly, the seat height is adjusted by means of threaded posts. These are rotated by the motors, and 'wind' the front (or back) of the seat up and down.

If you look at the underneath of the seats you will see the bottoms of the posts, and they may (may ... memory failing here) have slots cut in them, making them look like screw-heads. If this is the case then you may be able to turn them with a screwdriver and thus manually wind the seat up or down. BUT this might not work if the motor is still attached - you may (again!) have to remove the motor.

The switches are dead simple and (I'd have thought) easy to fix. The whole mechanism is very simple. Try putting 12v across the motor terminals and see what happens. That will tell you what is wrong.


Oli.

Hi, I had the drivers seat out last weekend for a similar problem. I connected 12v across the motor and found that it worked and brought the 'pistons' down (mine had no manual adjustment feature). I then undid the side switches and found that one wire on each switch had a dry joint and the wires had become detached. I soldered them on and found that the back motor then worked but not the rear. I stripped down this switch, two springs shot out and two ball bearings followed, so it is now knackered. However, the internals are all corroded and it wouldnt have worked anyway. So do'nt do this unless you know what you are doing with fiddly switchs. I am in the process of designing a more robust replacement using two black rocker switches and black plastic to mount them in. I post pictures and method if anyones interested.

Hi, I have taken this directly from page 17 of the owners manual

Emergency Adjustment

In the event of a failure of the electrically operated seat adjuster, fore and aft adjustment of the seat can be obtained using the hexagon-socket-screw key contained in the tool kit. The seat can then be adjusted by turning the servo motor located at the front of the seat

Only fore and aft adjustment but might be able to find a slightly more comfortable position. Otherwise get yourself to a breakers yard an start looking
