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!

Slight back and forth unwanted moment of power front buckets.


Check under the seat or beside the seat.. there should be a bar there which is a manual release... it sounds like it didn't pop bk into lock position... just wiggle it to set it in full close position... if your not sure what way it goes move it all the way in one direction and push on the seat.. if it clicks and will not move then you got it and if not... pull the leaver the other way and repeat seat push

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.

GMC Yukon Seat Switch


You don't mention what year your Yukon is ? This could very well be a control Module problem .
I'll post how the power memory seat's work or are suppose to work !

Memory Seats Description and Operation

Battery voltage is supplied to the memory seat module through a 25 A circuit breaker. The memory seat module supplies the seat adjuster switch assembly with a battery positive reference voltage. While the seat adjuster switches are in an inactive state the switch contacts are closed to the adjuster switch common circuit. When a seat adjuster switch is pressed to an active state the switch contact is closed to the reference voltage circuit. Battery voltage on a switch signal circuit indicates to the memory seat module the switch status is active. Each seat adjuster motor is controlled by the memory seat module through 2 motor control circuits. While the seat adjuster motors are in an inactive state the motor control circuits are closed to ground circuit contacts within the memory seat module. The memory seat module operates the seat adjuster motors by switching one of a motors control circuits to battery voltage. The seat adjuster motors are bidirectional and the direction of adjuster motor rotation is determined by which of the adjuster motor control circuits is switched to battery voltage while the other remains grounded.


Memory Set/Recall Operation
The seat adjuster motors are equipped with internal position sensors. The adjuster motor position sensors are monitored by the memory seat module and are used to determine the seat position when storing or recalling memory settings. The driver seat adjuster motors use potentiometer type position sensors. The position sensors are supplied with a 5 V reference and ground circuits from the memory seat module. The position sensor signal circuits return to an analog input within the memory seat module. During adjuster motor operation the position sensor provides a voltage change proportional to the change in revolution of the adjuster motor shaft. The memory seat module monitors the voltage from the position sensor signal circuits to determine the adjuster motor positions when storing or recalling memory seat position settings.
The memory recall switch assembly on the driver door provides inputs to the driver door lock/window switch. Battery voltage is supplied to the memory recall switch assembly from the driver door lock/window switch. When a RCL 1, RCL 2, or EXIT switch is pressed, the switch contacts close the appropriate switch signal circuit to the battery voltage supply circuit within the memory recall switch assembly. When the driver door lock/window switch receives active switch signals from the memory recall switch assembly, the appropriate commands are sent to the memory seat module using the GMLAN Serial Data circuit. The Body Control Module software version determines the personalization features available.
Memory seat recall operation is allowed only with the transmission selector lever in the PARK position while the ignition is on. The transmission selector lever position data is provided to the memory seat module by a message through the GMLAN Serial Data circuit.

There are somethings listed you are not familiar with , like GMLAN Serial Data circuit ,maybe Body Control Module software etc... GMLAN is a communincation network that the computers on the vehicle uses to share information , transmit commons etc... you can google it to read about it .

There are DTC'S - diagnostic trouble codes that can set in the module in control . Do you know what DTC'S are .

DTC Descriptors
DTC B1825 01: Driver Seat Recline Position Sensor Circuit Short to Battery
DTC B1825 06: Driver Seat Recline Position Sensor Circuit Short to Ground or Open
DTC B1825 5A: Driver Seat Recline Position Sensor Circuit Plausibility Failure
DTC B1850 01: Driver Seat Lumbar Horizontal Position Sensor Circuit Short to Battery
DTC B1850 06: Driver Seat Lumbar Horizontal Position Sensor Circuit Short to Ground or Open
DTC B1850 5A: Driver Seat Lumbar Horizontal Position Sensor Circuit Plausibility Failure
DTC B1860 01: Driver Seat Lumbar Vertical Position Sensor Circuit Short to Battery
DTC B1860 06: Driver Seat Lumbar Vertical Position Sensor Circuit Short to Ground or Open
DTC B1860 5A: Driver Seat Lumbar Vertical Position Sensor Circuit Plausibility Failure
DTC B2355 01: Driver Seat Front Vertical Position Sensor Circuit Short to Battery
DTC B2355 06: Driver Seat Front Vertical Position Sensor Circuit Short to Ground or Open
DTC B2355 5A: Driver Seat Front Vertical Position Sensor Circuit Plausibility Failure
DTC B2365 01: Driver Seat Rear Vertical Position Sensor Circuit Short to Battery
DTC B2365 06: Driver Seat Rear Vertical Position Sensor Circuit Short to Ground or Open
DTC B2365 5A: Driver Seat Rear Vertical Position Sensor Circuit Plausibility Failure
DTC B2375 01: Driver Seat Assembly Horizontal Position Sensor Circuit Short to Battery
DTC B2375 06: Driver Seat Assembly Horizontal Position Sensor Circuit Short to Ground or Open
DTC B2375 5A: Driver Seat Assembly Horizontal Position Sensor Circuit Plausibility Failure

5) Memory Seat Module is under the front of the driver seat , you could look under an see if all the connectors are fully seated.

The best diagnostic step would be to hook up the factory scan tool an see what the computer is seeing as far as inputs from the switch an outputs it's sending . I wouldn't suggest you take the seat apart an try testing electrical inputs etc.... unless you very familiar with automotive electrical systems an circuits .

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.

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.
