SOURCE: I pulled the seat all the way forward on my 1990

use the buttons to move it back but shake the seat side to side. sounds like your track on the seat has gotten in a bind with the one on the floor. just wiggle and jiggle till it starts to move and dont go all the way forward in the future

Why did both power seats stop working in my 2006 Chrysler van?


did you check for rat bites on the wiring or on bonnet open position?
even there is a chance for switch problem or low battery.

Drivers seat 2000 outback


So here is a diagram of the seat circuitry for your car. Since every other function works except the forward/backward slide function, that leaves basically the forward/backward slide motor, the seat switch, and/or the wiring. If you can verify that the wiring under the seat is in good condition without obstructions, chaffed wires, and/or wires pulled too tight, then it's safe to say it's down to just the motor and/or the switch. Sometimes if the passengers front seat has the same switch, you can plug it in to the drivers' side connector and see what works and what doesn't. If the seat works fine with the other switch, then that's all it needs, if not then it will need a motor. If the other seat doesn't have a switch then you can find them at wrecking yards, or just supply power and ground to the motor in question to see if it works. If it does, then you know you kneed a switch and if not then a motor.
I hope this info helps!~subyguru~

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.
-----------------------------------------------------

  • 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.

Trouble With Seat Controls


There is an Open Campaign on the 06 Sonata - POWER SEAT SWITCH REPLACEMENT
(CAMPAIGN T82), but not on the 2001 sonata. If a 2001, it would be out of warranty - the control switch is most probably the problem... replace the switch. However, you wrote 2009 Hyundai Soinata - that would still be under warranty. Take it into a Hyundai Service Department - they'll diagnose the problem and fix it.

Power front seats


Before you start beating up thing's , test the electrical circuits. Do you know anything about automotive electrical systems ? How to use a volt meter an a wiring diagram to test for B+ power to the switch an testing the ground .
Does your envoy have memory seats ? Your vehicle has four or more electric motors to control back an foward , up an down etc.. the odds of more then one motor being bad at one time are highly unlikely .
Look under the seat any trash under there keeping it from moving ?
If you have memory seats there is a control module involved in making the seats work . If it has memory seats it could have DTC'S - diagnostic trouble codes .
DTC B1735, B1740, B1745, B1750, B1755, B1760, B1815, or B1820
The seat adjuster switches are inputs to the driver and passenger seat modules. The seat modules supply the adjuster switch assemblies with a battery positive switch supply circuit and monitor the switch signal circuits. In an inactive state the switch signal circuits are floating and when a switch is pressed the signal circuit is closed to the switch power circuit within the adjuster switch assembly. When battery voltage is present on the switch signal circuit the seat module determines the switch status to be active.
