I put some used camaro seats in my GTA until i can get them recovered.. Driver seat will tilt up and down in front but will not go forward and back and move up and down. I connected the orange to orange and balck to black. So I dont think wiring is an issue. Do you replace the motors or do you just buy a complete bottom rail with motors or is it more likely the switch is out? I dont know which is more prone to be the problem

 

All of the above, but id start with the switch.

 

i'm having similar issues with my seats...did you find out if it was the motor or the switch?

 

I ended up swapping out my seats for 4th gens.
I did end up having to run a new power wire even though my floor wiring showed good power.
