if going backward is working,and foward is not,, easy
,1st determine what is defective-so u know what to replace/repair-2 things only ,[1-switch or 2- motor under d seat]
by presing the backward swicth,, you can hear the sound of the motor running and u can see the seat is going backward...
1-now by pressing the foward switch, and you hear the motor running but not that strong like the rear ..and the seat move an inche /a little and stop,,.then u have a defect weak motor,
2- now by pressing the foward swicth and u dont hear any motor running then the switch is most likely defective
defective switch -repair- spray contact cleaner,remove cover switch,penetrate inside
defective motor-repair-remove motor replace inside carbon,,.chiepest way not to spend to much money..
i suggest even once a month,lubricate all power seat/even not powerseat/,door hinges/.trunk door/.power antenna./ .by spraying lubricating oil,. for maintanace,..you can save a lot..

broken bar under seat or worn

There are two bolts in the front and two bolts in the rear, remove them and then disconnect any wiring connectors and pull the seat up and out of the car, careful not to damage the dash or body panels.

Try removing your seat bottom to access small motor that moves the seat,Tap on seat motors while holding seat switch in the forward position.

MY POWER SEATS WILL GO UP & DOWN AND WILL TILT FORWARD & BACKWARDS BUT WILL NOT GO FORWARD OR BACKWARDS. IT JUST MAKES A HUMMING SOUND WHEN TRYING TO GO FORWARD OR BACKWARD. IS THE POWER SEAT SYSTEM A GEAR SYSTEM, OR HYDRAULIC SYSTEM?
