I have a 1998 clk230 .The drivers seat control button will only move seat forward when presed for backward.consequently the only way to get the seat to go backward is to press the memory button .

check switch for proper operation //check motor control for power ,connections and wires are not damaged or disconnected===check seat track for debris or something stuck

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..

First try as fallow, get in to the seat, then keep tight your foot on floor and give a good press backward to the seat and operate the seat switch towards back, just release and do it again keep going that way it will start to move back words, if it start to move do it few time and do it every time you get in to the car at least two time per day continue it for one week, It will be OK otherwise need chassis no for more information,

On ABS light most common problem is ABS control module , they failing left and right.
As for the seat adjustment , sound like you need a new seat switch.

the electric motor for forward and back is bad salvage yard easy to change let me know hey vote for me ok

is look like a fuse blowen you need to replace it look in the munual book

i had the same prob when i got my durango.i set the seat where i was cumfortable and still where my wife could be cumfortable drilled two small holes on the side of the rail and shot two rivets through it.all the other controls work the same but it doesnt go back and forth anymore.works for me ,alot cheeper than a power seat.

it could be the electrical switch that controls the motor, that is if there are two switches to the seat button which controls the motor.

I'm assuming this is a power seat. If so, there are separate motors that control the various functions of the seat such as forward/backard, recline, lumbar support, etc. It could be that the motor or an electrical connection to the motor for the forward/backward motion is faulty. Normally all of the motors would be on the same power circuit, so if some of the functions are working then it is probably not a blown fuse.

Just one other personal observation, I have actually seen an instance where some loose pocket change had spilled under the seat and a quarter had become wedged in the track that the seat slides in and had jammed the tracks so tightly that the seat would not move.

One thing to note is whether or not you hear anything when you try to move the seat forward/backward. If you hear a click or a buzz when you press the button then that could mean that something is physically jamming the seat tracks. If you don't hear anything when you press the button, then that more than likely means a problem with the motor or the electrical connection to the motor.

Good day;
What year is you car? Does the other controls work for the seat? and just to clarify the seat won't go forward of back?


Cheers
