Best to you.

Seats - Third Row
The third row seat:

• is three-passenger seat.
• a 60/40 bench seat.
• folds down for more cargo area.
• has optional power fold down seats.

Third Row Power-Fold Seat
CAUTION: To prevent possible damage to the third row seat or the safety belts, make sure that the safety belts are not fastened when moving the seat to the load floor position.
CAUTION: Make sure that no objects such as books, purses or briefcases are on the floor in front of the third row seats or on the seat cushion before lowering the backrest(s).
The third row power-fold seat consists of the following electrical components:

• right third row seat relay.
• left third row seat relay.
• right power-fold seat motor.
• left power-fold seat motor.
• right front third row seat switch (if equipped).
• left front third row seat switch (if equipped).
• right rear third row seat switch.
• left rear third row seat switch.

For the third row power-fold seat to operate, a shared ground is supplied by the body security module (BSM) to both of the power-fold seat relays, enabling the seats to then be moved by pressing one of the third row power-fold seat switches. The third row power-fold seat operates only when the vehicle is in PARK and the liftgate glass, liftgate door or any entry door must be open.
The third row power-fold seat motors transfer movement to a drive gear assembly to raise and lower the seat backrest. The power-fold seat motors rotate a short drive cable which is connected to the drive gear assembly.
The relay's are located in Aux. relay box #2

original harness was set up for seat belt indicator and such..may need to run a separate power coupling for the power seats to work..

-----------This will help.Thanks.

First of all, check under the seat where there should be a cluster of wires. Sometimes if the power seat is used alot by sliding back and forth, without this cluster of wires being secured, occassionally a wire can get cut.
The runners on which the seats move are metal and cut wires easily. Secondly, the plug also located under the seat could have gotten wet or accidently came unplugged from someones feet in the back or objects and debris.
Another possibilty that will keep power seats from working is the power seat motor. In most cases, this small electrical motor is located directly under the power seat control panel or very nearby
Also you could check the fuses in the fuse box, located directly above the driver's left foot area. Power seats are usually on thier own circuit which means if the power seat fuse is blown, that is the only malfunction that will be noticed, versus other circuit which have many power items on one circuit. For example dash light, clock, and temp lights don't work, one fuse will fix the problem. Power seats operate on one fuse circuit which could have one or more fuses depending on the options of your seats. E.g. heated or not, lumbar, etc.

hello, have someone check all fuses-and plugs for the power seat, they may be a relay for this problem, can call autoparts store and ask about any relays for the heated seats and the power seat, if thats not it you may have to replace, electric motor for seat, sounds like a fuse, the way it all quit working..

You might want to try disconnecting the negative battery cable for 5 minutes and then reconnecting it. This procedure fixed my seat that was not working. It works fine now. I know it sounds too good to be true but it usually works

both my power seats are not working at all ..it first started with driver seat , to make seat move forward and back tilting the recliner was working then it went out ..not working either..then after a month later my pasenger seat stopped working as well... what might be the issue..please reply

I have a 1995 Jimmy and the power seats didn't work. I put my own power wire with a fuse between the seat and the live wire under dash. It works fine.
