On my 86 chev caprice, my electric motor seem to be locked up and my seat will not move forward or backward , I need to move seat back so I can remove bolts to remove driver seat to look at motor, how do i manually move seat back???????

check switch for proper operation //check motor control for power ,connections and wires are not damaged or disconnected===check seat track for debris or something stuck

Could be a bad switch or motor, or something jamming the seat movement.
Can you hear the motor running on both switches and directions?
I don't think they would have two fuses for the seat, but that might be a possibility.
Hope this helps.

make sure nothing is lodged under the tracks this is common things get thrown under the seat and stops them in the track

ssqsantiago, What you have to do is look under the seat and look for the electrical connections. You may find that one of the connections has a broken wire. If not, then disconnect each connection one at a time and look for any rusted pin or wires. If there are none of the above then what you can do is to figure out which motor moves the seat forward and backward and apply direct power to the motor. You will need a 12 volt battery for this and wires long enough to reach the motors connection. If the motor does not react to the power source then reverse the wires. If the motor still does not react at this time then the motor will have to be replaced. What you can do in the meantime is remove the motor and try to move the seat manually. Good luck with this.

Check the fuse box for a blown fuse, both seats may operate on one fuse depending on the model of vehicle and the fuse may be located either under the dash on the drivers side or in the engine compartment on the drivers side.

You need to check for power at the motor when you try to activate the switch. If there's power then you have a drive cable issue. If this is a manual seat then the problem is the actuator assembly itself,the cable,mechanism,etc. Remove the seat & take a good look at it. You'll see a problem,write back.

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 electric motor for forward and back is bad salvage yard easy to change let me know hey vote for me ok

it could be the electrical switch that controls the motor, that is if there are two switches to the seat button which controls the motor.

I'm assuming this is a power seat. If so, there are separate motors that control the various functions of the seat such as forward/backard, recline, lumbar support, etc. It could be that the motor or an electrical connection to the motor for the forward/backward motion is faulty. Normally all of the motors would be on the same power circuit, so if some of the functions are working then it is probably not a blown fuse.

Just one other personal observation, I have actually seen an instance where some loose pocket change had spilled under the seat and a quarter had become wedged in the track that the seat slides in and had jammed the tracks so tightly that the seat would not move.

One thing to note is whether or not you hear anything when you try to move the seat forward/backward. If you hear a click or a buzz when you press the button then that could mean that something is physically jamming the seat tracks. If you don't hear anything when you press the button, then that more than likely means a problem with the motor or the electrical connection to the motor.
