The easiest way to repair this is to find your short to ground and not "butcher' 'the factory harness. It sounds to me like you know some about the system you are repairing so just check the 3 feet of wire that runs from the seat to up under the dash... I'm sure you will be able to locate it. It all runs under the carpet and trim up under the drivers side of the dash.
There's a red and lite green wire going to the seat motor, and a red and dark green going to the seat heater. Do you know where the wire popped off at ? Or what no longer works ? It could be something with the seat belt sensor or the air bag sensor too.
Go to www.hmaservice.com and register your vehicle by VIN #.. you'll then have access to wiring diagrams, shop manuals, service bulletins, illustrations, etc.
There are 3 cables under the driver's seat.
1) 1 (single wire) goes to the illumination light of the transfer case position plastic lense panel (underside)
2) 1 (single wire) goes to the seat belt harness for the seat belt warning light
3) 1 (multi-wire) goes to air bag sensor located directly under the seat.

They are in each door. But there is a tech service bulletin on broken wires under driver seat. There is a multi splice union under rug, under drivers seat. You will see green corroded wires that need to be cut off till not corroded & reattached. I have run into that more than bad switches.
No fuse.These seats are protected with relays and a seat module.The module is under the drivers seat.There are 3 connectors and it would be hard to check all these wires for power to the motors.First look under the seat and make sure none of the connectors came apart under the seat by something that might have been left or rolled under it.The 2 main ones you can check are the connector 2 terminal C and connector 3 terminal A.C is a black wire which is ground and A is a red wire which is the feed power wire.Connector 2 is green and 3 is black.If the ground and power wires are good then you could have a bad drivers seat module.What I would do is go to the salvage yard and find a used module to try.Good luck.
Once I had this problem and had to strip the wires under the seat and hook them up to another power source ((Your Battery)) Find the wire that moves the seat back and strip the wire, then hook it up to a seperate wire leading to the battery ((I used jumper cables)) If successful the seat will move back and you'll be able to remove your seat.
The controller could be bad but I would probe the related wiring first. From your symptoms it sounds like something can not handle the electrical load. You turn the F/R seat heater on but then you turn on the F/L and the whole system fails. It does sound like the source of the problem will be under the drivers seat. Testing needs to be performed to confirm and identify the source. Both seats share the same fuse and ground. This circuit may have a damaged wire or connector somewhere. Inspect and test as much as you can. Also look underneath the seats for anything. Customers are not aware that personal belongings and trash get pushed underneath the seats and will damage wiring. Also excessively moving the seat forward and back will weaken the harness over time. Please write back and let me know what you need. If it is more diagnostic information or suggestions just let me know. Good Luck
