2011 gmc terrain power seat wont recline up
All of the functions on the seat are controlled by "one" fuse. Forward, back, up, down and recline, If one is inop. The whole seat bottom needs to be replaced. Now if you hear an audible bump noise when you rapidly flip the recline switch back and forth, you may be able to free it up by working it and see if that helps to free it up for sometime. When those motors sit in one position day after day month after month without being moved, they tend to "stick" but if you can't get it to free. The bottom of the seat will need to be replaced. Those are not cheap by no means and it would be a good idea to let a professional do it unless you are up to figuring out where all the brackets and nuts and bolts go and the proper wire routing because it is very tedious work. Not trying to scare you from doing the job but just stating a fact. But I hope you get the issue corrected. Jesus loves you, John 3:16-17 (KJV) :o)

What and where is the servos
- A servo is a mechanism, usually a motor of some sort, that drives another mechanism. On a passenger aeroplane, for example, the control surfaces are too difficult for the pilot to operate because there is so much wind pressure against them, so they use hydraulic servos to move the elevator, flaps etc.
- On a car, the drive by wire throttle control is a servo, which is electronically controlled by the computer, depending on the throttle position under the driver's foot.
- In effect, the power steering ram on a car is also a servo, which is powered by the p/s pump, and controlled by the valves in the steering column.
- On a smaller scale, the air conditioner has servos that open and close the relevant air duct flaps when the dashboard controls are shifted to control the flow of air in the car. Please note that on older cars, and some new ones, these flaps are not controlled by servos but by cables.
- The remote controlled central locking on a car has servos in the doors that open and close the door locks when the remote button is pressed. On some cars these door lock servos are small electric motors, on others they use vacuum operated pistons, also called servos.
- Hope this answers your question!
