Try moving seat all the way up,then make sure nothing is blocking the tracks and clean. spray some dry-selicone (white grease) or try some wd-40 this may take a few times.

Power seat motor


Fron first principles, the reverse movement of the motor is caused by reversing power polarity to the motor. If he motor runs in one direction and not the other then it isthe switch. It is not conecting power to the reverse contact. Check.replace switch.

Subaru outback all wheel drive electric seat switch stuck


I just went through and determined it was the switch. My wife had accidentally moved the seat almost all of the way forward - and the reverse did not work at all - she was very cramped. After going thru fuses and seeing that none were blown I looked for loose wiring under the seat and found none. I was about to pull the seat when I stopped and decide to pull the side cover first. Item 5 in the photo below. Once that was off access to the switch was easy - item 3. The box actually contains a set of 3 switch housings each with 2 switches on it - total of 6 for each direction. I unplugged the large connector to this switch. Then I cut some wire off of a roll of wire i had in the garage and stripped both ends. I put one wire into the power contact (red) and the other into ground (black) and then took the other end of both wires and connected them across the other contacts in the connector. Pretty quickly I could determine which pair of contacts controlled which motor. I got the right combination that allowed me to operate the seat-reverse motor and get the seat back into the right position... problem solved. I still need to find a replacement switch box at a junk yard but no hurry now that the seat is back to a comfortable position.

1999 Cadillac Deville Driver side power seat not working


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.

My power driver's seat 1999 lincoln continental keeps returning to the full back position even when i drive.I changed the entire seat frame with new motors and gears, $500.00 no fix. I have to pull the #39...


does this have automatic seat positioning when you open the door or hit the unlock button on your key fob?

here's how it works:

Seats — Programmable
The memory seat system allows automatic positioning of the driver seat to two programmable positions using the message center, the key fob or the keypad on the door.
Seats — Driver Seat Module
The Driver Seat Module (DSM) is located under the driver's seat and is attached to the seat frame. The DSM will:
  • control the movements of the driver's seat and power exterior rearview mirrors
  • store and recall seat and mirror positions of two personalized settings
  • receive all power seat and mirror control inputs from the Driver's Door Module (DDM) through the J1850 communication network
  • move the exterior rearview mirrors downward when the transmission is shifted into reverse, if enabled.
Seats — Driver Door Module
The driver's seat regulator control switch is connected to the Driver Door Module (DDM). The DDM receives the driver's seat regulator control switch input and communicates the direction of movement over the J1850 communication network.
-----------------------------------------------------
Visual Inspection Chart Mechanical Electrical
  • Front seat tracks obstructed.
  • Seat at limit(s) of travel.
  • Open fuse junction panel Fuses 39 (10A), 41 (20A), and 28 (10A).
  • Open power distribution box Fuse 13 (30A).
  • Loose, corroded or damaged connectors.
  • Damaged switches.
  • Damaged motors

------------------------------------------------
Also, the dealer can run a scan on your seat modules with his tester and tell you what the codes are. They should only charge an hour to do this. Then you can decide what to do. Call your dealer and ask how much to run the scan test.

Power seat on drivers side of 1996 buick park ave. wont go in reverse every ting else works ok


Chances are one of the motors has gone out. There are 3 motors for each of your power seats. One controls the forward/backward motion, one controls up/down/tilt, and the third controls the reclining seat back. In my '95 model, there is one fuse for the seats under the driver's side dashboard. There should be a diagram inside the fuse panel cover denoting which one controls the seats. Hope that helps!

2005 KIA Optima EX 8-way power seat problem


Hi there,

There are numbers of possible causes to your problem. There might be something causing the movable parts to stuck up. It could be the limit switch, or the motor itself. To test the motor, you can connect it directly to the battery then check if the motor runs smoothly. Then reverse the connection and observe if it reverse smoothly. If the motor is OK, then your problem is with the switch...

Regards,
Jeep Brainy

Power driver seat will not adjust forward or back.


My intuition tells me that the 6 way power seat track forward / reverse motor is bad. Sometimes you can replace just the one motor but most often a whole new power seat track is the only way to repair. It is not too bad to replace but the seat will have to be removed from the car and placed upside down to access the track assy. There are 2 bolts in the front of the seat and 2 bolts in the back of the seat that hold it down to the floorboard. Once it is loose you can rock the seat backwards to access and unplug the electrical connectors.
