Power seat moves back and forth each time key clicked to unlock car doors. It doesn't stop moving until I manually touch the seat power button.

This is a problem when people use the FOBs all the time. The key lock corrodes and won't turn. Spray some lube in it and work it back and forth. If and when it starts to move, use more lube. It has to be cleaned out. If it doesn't move, you'll have to replace it. DO NOT use so much pressure to turn it and it bends the key.

may be you need a tool and you can find some good ones here: diyobd2.fr

Try taking off the neg battery post and wait. reinstall to reset system and see if that works for you.

Pop off interior door panels & lube up door lock actuators with a good penetrating oil, move lock buttons back & forth manually & try to use switch to move back from unlock then to lock & back in forth. If they will not free up you will need door lock actuator.

that is easy find the motor under the seat that moves the seat back and forth take and neg wire and a hot wire carefully touch the twoo prongs going to the motor after diconnecting the plug going into the motor. it sould go forward one way and croos the wires to get it to go the other way if this works get a new switch and have a working seat.

Ther is no way you can roll it back manually , but you can try to check fuses .
If they Ok , it might be the seat switch itself.

If it's a click from dash area, try spraying lubricant on areas where door rides across, and keep working door back & forth until it moves easier. It may be a circuit breaker tripping from too much load. Does turning key off and back on get it going again?

that is the interior lights and alarm,remote module

Open the door panels and lube all of your lock mechanisms. They tend to get stuck and it harms the locking motor. After I lube mine up, they freely move. Just spray some lithium grease and manually lock and unlock the door with the rocker until it moves very easily. You'll probably have to do this once a year like I do.

Turn the key to the "ON" position; do not start the vehicle.

Press on the button of the 3 available to you on the vehicle and hold it until advised to release it.

Take your garage door remote transmitter, and press the button that you use to make the garage door operate, hold it down until advised to release.

With the vehicle button being depressed, and the remote button depressed, hold the remote up against the area where the 3 buttons are located. It needs to touch the area wher the buttons are.

Keep moving the remote around slowly, back & forth, spin the remote, until the red light starts to blink slow.
After the light begins to blink slow, hold the remote in that exact position until the lamp blinks real fast.
Relase both buttons.
Repeat for a second remote on another button.
