Driver seat goes foward but not back

you could try removing the electric runners off your original seats and fitting them to your new seats

Check for an object in the seat tracks blocking movement. A napkin, a coin etc. .

I'm not familiar will your vehicle but check the basics , fuses ,see if there is anything under the seat stuck in the seat track. Find a wiring diagram an see if there are any relays an seat control modules involved ! You owners manual should tell you fuse position !

something stuck under seat? gear strip on motor

The seat has a transmission to move the seat up, down, foward , & back. Screw jacks adjust the seat up & down. Cables move the seat forward & back. The cable it seems had to break or the end of the cable has rounded out. Possibly the cable rounded out the seat it rides in the transimission housing too. You will need to remove the seat to find out

will or wont move foward?
you can get to the wiring block under seat. isolate wiring from motor 1 of three, (middle motor- foward back, front motor - front seat base up / down, back motor - back seat base up /down) does it work of mem. buttons? or when u lean seat foward (entry assist).

If the seat has a lever to allow entry to rear seat the fnt seat back and seat roll foward[2 door jeep]. Move the seat back back to normal and push loose seat all the way foward and then all the way back.let me know if that helps

The power seat relay needs to be replaced. The seat can not be moved manually unless it is removed from the car and taken apart

Thre's three motors or more that move your seat the one that controls foward/back went bad or harness under seat came apart.

the back seat does move foward the jack is bolted down its a pain in the ***
