Probably the switch is installed backward in its cover so remove the switch and rotate it and put it back

I just had this problem fixed with a Tech 2 tool in my '03 yukon xl denali. The seat has a control module underneath of it that controls the 2-position memory, the power seat functions, etc. It needed to be reprogrammed - about $200 at the dealership, or free if you 1) have a good relationship with your service manager, or 2) own or know someone with a Tech 2 tool.

At first I thought it was because I had a Canadian model truck (the headlight switch is stuck "on" at all times no matter what position it's in, and the rear air controls are in celcius and not farenheight).

I'm assuming the switch worked before, and you may have encountered some sort of electrical issue (like a dead battery, or you gave someone a jump, you have a bad ground, you just installed an aftermarket stereo, you used a computer tuner, etc.).

Hope this helps!

My driver side seat won't go all the way forward. But when I let it back it goes back and goes down. When I move it forward it lifts up high but don't go forward enough for me.


Seat adjustment ranges are sometimes limited and sometimes there is a fault, such as a coin or something falling into one of the runners.

Cars intended for the premium market often have forward/back, up/down and sometimes tilt adjustment for the driver seat while for the small car, basic or budget market usually only have forward or back. Because on average a person who has shorter legs and needs the seat forward will also have a shorter body so enterprising designers have made the seat runners of some models slope upwards to lift the driver as the seat is moved forward.

Adjustable steering columns are fairly common, though only in the rise/fall plane. I haven't seen a telescopic column for many years. What is really needed is adjustable pedals but designers and manufacturers are very reluctant to go down that avenue, though there are companies specialising in such modifications.

You need to be on the ground on your knees with a good light looking under the seat to see if the available adjustment range takes the seat to the true limit of its travel in both directions.

How can I access the battery in a 1993 Mazda E2000?


The battery is under the drivers seat. Move the entire seat forward but sliding the leaver at the front bottom of the seat (as you would to adjust the seat) and push the whole seat as forward as you can and then wind the actual seat back forward (dial on the door side of the seat back). Pull up the plastic trim and unscrew the metal capping. Under there you will find the battery and also, what I think is, the overflow container for the radiator.

I have a 2006 lincoln ls sport and the drivers seat is stuck in one position there is only power to the lumbar


The dirver seat module is attached to the underside of the seat frame. It must be calibrated if replaced. The dealer can use a tool to get failure codes (DTCs) from teh module. 1/2 hour labor charge to extract codes.


Front Seats
The front seats have the following features:
  • Driver memory
  • Power lumbar (optional)
  • Manual lumbar
  • Horizontal, vertical front and rear tilt adjustments (driver)
  • Horizontal, vertical front tilt adjustment (passenger)
  • Power recline
  • Climate controlled (optional)
Adjustment of the seat may be accomplished with the seat control switch located on the side of the seat.
--------------------------------------------------------------------
Principles of Operation
Driver Power Seat - Memory
NOTE: The memory power seat track may stall when operating at 0°C (32°F) or below. Once the vehicle's interior temperature rises above 0°C (32°F), normal operation should return.
The driver power seat is controlled by the driver seat module (DSM). The DSM does not need to be configured, however the driver seat does need to be calibrated when the DSM is installed. The driver seat control switch provides voltage to the DSM when activated. The NEUTRAL position of each driver seat control switch position is a ground state through the seat control switch contacts. A voltage input causes the DSM to power the appropriate motor until the input is removed. Ground is the normal state of the motor circuits through the DSM and is not switched to control the motors. The DSM internally switches the appropriate line from ground to power to adjust the motors.
As the seat is adjusted, the DSM constantly monitors the motor position sensors to record the current seat position. The DSM will remove power from the motor upon termination of the seat control switch input or if the DSM does not see movement from the motor by monitoring the position sensor. The DSM must be calibrated to the seat track it is controlling. For additional information, refer to Seat Calibration. Once the DSM is calibrated to the seat track, it will only allow movement within the calibrated range.
Seat Calibration
The DSM is calibrated using a diagnostic tool. The calibration procedure automatically powers the driver power seat through its full range of motion and records the FULL STOP positions by monitoring the motor position sensors. Once the FULL STOP positions or range of the seat have been recorded, the DSM will only operate within the calibrated range. Any input attempting to drive the seat beyond the calibrated range will be ignored. This calibration is used for all seat control functions including manual switch control and memory recall positioning. During the seat calibration, the DSM may identify a function that is inoperative, such as a position sensor not changing. If the DSM identifies a concern that has a related diagnostic trouble code (DTC), the DSM will set the related DTC at the end of the validation procedure.
The calibration procedure powers the seat track adjustments to the end of their travel, which is determined by the DSM sensing a change of state in the motor position sensors. If there is a concern with the seat track or motor position sensor that limits the travel, the DSM will interpret the stopping point as the end of travel and store the position. The DSM is not able to determine if the seat has moved to its FULL TRAVEL position. It is only capable of monitoring and storing the amount of travel seen by the position sensor changing states.
For additional information on carrying out the power seat calibration procedure, refer to the diagnostic tool operating manual.
Memory Seat
Memory seat positioning can be recalled with the memory switches on the driver door panel or a programmed remote keyless entry transmitter. In either case, the DSM receives a memory recall 1 or 2 command from the driver door module (DDM) over the SCP communication network. The memory recall switches are a hardwired input to the DDM. The DDM also receives the remote keyless entry transmitter signals. Once a valid memory recall command is received from the DDM, the DSM moves the driver seat to the position stored in memory by powering the appropriate motors and monitoring the motor position sensors until the position is reached.
This system allows automatic positioning of the driver seat to 2 programmable positions.
  • To program position 1, move the driver seat to the desired position using the seat control switch. Depress the set button. Within 5 seconds, depress button 1.
  • To program position 2, repeat the previous procedure using the set button and button 2.
  • To recall position 1, depress button 1. To recall position 2, depress button 2.
A position can only be recalled when the transmission selector is in PARK or NEUTRAL. A position may be programmed at any time.
Easy Exit/Easy Entry
The easy exit function moves the seat backwards about 2 inches when the ignition key is removed from the ignition switch. The DSM receives a key out command over the SCP communication network and powers the driver seat rearward. This function will not operate if the seat is less than the travel distance to the end of the track, or the function has been deactivated at the message center driver personality settings. The DSM will also cancel this operation if a valid input command is received, such as the seat control switch or memory recall request.
The DSM will record the current seat position before powering the seat for an easy exit function. This recorded position will be used to return the seat to this position on the easy entry operation. During easy entry operation, the seat is returned to the position previous to the easy exit operation. Easy entry operation will be cancelled if a valid input command is received by the DSM.
Passenger Power Seat
The passenger power seat motors are hardwired to the passenger seat control switch. The circuits are normally at ground through the seat control switch. The individual circuit is switched to power when the specific adjustment position is selected.

When i move the driver side controls in my 2003 yukon to make the seat go forward, it goes back. when i move it to go back, it goes forward.


Hi.
Its most likely the motor connector plug is reversed polarity. If you have been repairing of have at any stage done a recent past perfomed any modification or adjustments to the seat wiring . You should revisit your repair ! Hope this helps Good Luck

I found this post area while looking for a way to fix my stuck 2001 Camry LE drivers seat. Sure enough, while engaging the seat motor (it could be heard making an initial clikc), I hit the front rails a coupel time prettysolidly with a rubber mallet. That fixed it!

Thanks to all for providing a quick fand easy way to get the seat moving again!

The front passenger seat is jammeed. Whenever I push the button to move the seat back and forth, it only goes a short way and stops. Currently the seat is jammed forward and I cannot get it to slide back...


Check to be sure something isn't jammed under the seat to prevent it from moving past the point. Also check your electrical connections to be sure they are plugged in tight. Your seat may move to a point and unplug (but remain plugged in). Next there are control circuit boards under the seats that can go bad and cause intermittent problems.

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.
