There is a ratchet system on the slide rail below the seat, sometimes the teeth on the ratchet wear out, especially when adjusted often. The hook holder that actually clamps onto those teeth, may be broken off or worn out aswell, and either of these will need replacement. Some models also come with air-suspension and a locking device, the spring on this device may be missing or worn, this will also mean a new one is neccesary for repair.

BUT... If you don't want to fork out, and are going to leave the seat in one position for a long time, may I suggest simply welding the rail to the seat, this is a permanent thing and would require you to throw away the entire sliding system, if you ever need to adjust the seat. Hope this helps you. Good luck!

1999 Chevy 1500 with power seats rocks forward or backward on breaking and acceleration.


You said "rocks forward and backwards not sliding.
upon that knowledge I would check the seat rails and see if they are still connected to floor of your truck. Sound as either the rail has disconnected at front or rear mount.
A simple fix is to replace bolt with new and installing an oversize washer or plate to underside of truck when installing replacement bolt

Drivers seat motor wont go back or forward but will go up and down


maybe something jammed in the rails or damaged motor. Up & down is ok because it has seperate motor. Easy to remove seat and have a look at the set up. Basically it's a long screw on the end of a motor that drives thru a captive nut in the seat. Sometimes the captive nut wears and causes "seat rock" fore and aft.

Bmw z3 passenger seat goes forward backwards but


It can also be theseat motor since there is seperate motors for up/down & forward/backwards. You can test the switch to see if you are getting power to the connector on the motor by using a multimeter.

If there is power to the motor, I would remove the motor and give it a tap on the ground. Alot of the time the motor is fine, and the tap will free it up again. If it doesn't work you may be up for a new seat motor. Giving mine a tap solved the issue with mine.

its the dreaded seat rock syndrome, plenty of fixes on the forums, basically you have to replace spacers in set drive mechanism. I did with the help of a friend after ordring bushes and it was quite easy.
