Polarity reversed on power seats ...when attempting top move power seats to the forward position..the seat moves backwards and visa versa.

Same thing happened to me checked everything found the problem was in seat switch box came apart, I just put back together and bam seat’s working again, check it.

Try unbolting the seat, lift it up, operate the motor and once u find the motor you are looking for apply 12v to one wire and ground to other going to motor... If it moves forward switch the polarity and see if it operates the other way verifying the motor is functioning well. While there check for power from the switch

Fron first principles, the reverse movement of the motor is caused by reversing power polarity to the motor. If he motor runs in one direction and not the other then it isthe switch. It is not conecting power to the reverse contact. Check.replace switch.

Check that the seat belt mount (often solid plastic or metal that holds the button side of the belt in place next to the center console) is not pinching and preventing the seat from moving forward and back. This happens on many Fords, so it might happen on some GM's too.
If you can hold the buckle mount out of the way while someone else moves the seat backward (or forward), it usually starts working OK again until someone moves the seat to the max forward or max backward position and it gets stuck again

Before you do any of the expensive things disconnect and reconnect the wiring to the seat I had the same exact problem with my 2009 Chevy Impala and was ready to take it to the dealer when I disconnected the power cables to it and reconnected them I found that one of the Harnesses was loose and the problem was solved

The control module for that is 400 dollars and the switch is 110.

the wirering for the drivers seat will have a wireing harness under the carpet this is the best way to tap into power for the seat

You can move the drivers seat back by turning on the power, getting in the seat and position your feet firmly on the fron flor with your back firmly against he seatback, and then engage the switch pushing back - while pushing like hell with your feet. You can actually hear the seat drive shaft turning while the seat moves back. The principle should be the same for moving forward, but pressure would have to be aplide to the back of the seat.

The reason is that your sliding grips have been slipped and therefore jammed at one position.

Remove the seat open it's sliding grips and replace it.

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
