SOURCE: Suburban seat problems

sounds like the motor brushes are about worn out.
Where you actually sitting on the seat when you applied power directly to the motor? If the motor is wearing out, it may work under little or no load but won't work when your weight is on the seat. Will the seat move while hitting the button if you also help push the seat in the direction you are trying to move it? If yes, the motor is weak. Change the motor, check, clean and lube the tracks, if nec., then see if that's better.

This is a common problem and you can buy a new handle at O'reilly's that will slide over what is still sticking out of the seat and tighten with a set screw.

The seat connects to the body control module, not directly to the buttons. You can get a diagram in a manual that can be bought from an auto parts store.

Can I manually adjust the power seat on my 98 explorer? Or can I be able to fix it w/o buying new seat or motor?

Your power seat can not be adjusted manually, if the motor in the seat is bad then yes you will have to replace it. Go to the motor under the seat and unplug it, test the wiring harness end of the connection for power with a meter, while operating the seat position, if you get power then the motor is bad, if you do not then you need to check the wires and fuses that supply that power, and the switch. Hope this helps, let me know
