SOURCE: POWER SEAT SWITCH ON 96 CAMARO WILL MOVE SEAT ALL

Camaros and Firebird/Trans-ams are notorious for electrial issues. I have owned several and I love them! I never experienced your problem my self, but obviously electricity is getting to the seat and its just a matter of process of elimination, so it sounds like you need to remove the switch and inspect all the connections, if no problems are noticed externally, then replace the switch first to rule out that possibity.

Before any of this, rule out the mechanical and obvious causes first before it costs you anything. Check the tracks that the seat slides back and forth on. I have frequent problems with change coming out of my pockets every time my foot gets heavy on the pedal (600hp vette)....so definity coins and other debris can cause the tracks to jam: cigarette lighters, pens, glasses, tools, fast food rubbish can all cause this.....

If its not any of these problems, it might be a relay

the 10 amp fuse you checked is for the lumbar support, there is also a 20 amp circuit breaker in the fuse box there are two of them on for each seat, the drivers side is # 35 20 amp and hear is were we need to start, remove the circuit breaker and test for 12 volt at the circuit breaker, if there is 12 volt try swapping the two circuit breakers and if the seat then works replace the circuit breaker, if not then you will need to get to the wiring plug-in under the seat and check for power to both orange wires if no power on one or both wires then there is a brake between the fuse box and the seat, look real close were the wiring has to bend at the bottom of the seat rail this is were we see most brakes, if there is power at both orange wires then you need to test for power at the gray wire coming out of the switch wile holding the seat adjuster in the froward position, if there is no power replace the switch if there is power replace the motor pack under the seat.

good luck

let me know if there is any thing else you need.

2009 Buick Lucerne, power driver seat won't adjust on seat or through memory button. Passenger seat works fine. Heater for both seats won't turn on. Checked fuses and relays, all ok


Your best bet , have it checked for DTC'S - diagnostic trouble codes first ! Electronic control modules involved ! Can't check with a OBD 2 code reader , need advanced scan tool . No codes , check B+ voltage and ground to the module .
Power Seat Inoperative (With Memory A45)
Memory Seat Feature Inoperative
Circuit/System Description
Battery voltage is supplied at all times to the memory seat module (MSM) from the MDL-MEM 10A fuse located in the rear fuse block. This voltage is used by the MSM for logic power and to supply battery reference voltage to the seat and lumbar adjuster switches. Battery positive voltage is also supplied at all times to the MSM from the PWR SEAT 25A circuit breaker. This voltage is connected to a power rail internal to the MSM and is used to drive the power seat motors, lumbar motors, and seat heater elements on vehicles equipped with heated seats. Each seat and lumbar adjuster motor is controlled by the MSM through 2 motor control circuits. The MSM connects all motor control circuits on the power rail to a common reference point whenever they are not in operation. This reference point is biased to approximately 2.5 volts. The MSM checks to see if the reference voltage is shorted to ground or battery before enabling any of the seat or lumbar motors.

Circuit/System Description
Reference voltage is supplied to the memory switch from the driver door module (DDM). When a memory switch is pressed, reference voltage is applied through the switch contacts, a series of resistors and thorough the memory switch signal circuit to the DDM. The door module then sends a serial data message to the memory seat module (MSM) indicating the memory recall request. The MSM then commands the appropriate seat motors to move to the pre-recorded seat positions stored in memory in response to the switch input.

Seat's are stuck


you said seats so I am assuming you mean 6-way driver and passenger. You also say you looked at all (my) fuses but actually the seats are controlled by 20A circuit breaker 7 in the battery junction box. If certain functions don't work, it may be due to failure of the seat adjust switch or lumbar adjust switch or any of the five adjusting motors

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

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.

Hi - I have a much loved 2004 SAAB 93 Aero sedan.


This has been happenning on my 2006 Saab 9-3 2.0 T also for about 2-3 months also. I have had no clues until today I learnt by accident that the lumbar support on my car's driver seat does not work anymore. Which means that there are broken strings/wires inside the seat and that move on braking and make clicking sound. I haven't checked my seat's lumbar support but will do soon.

Try your lumbar support adjustment and see if it is moving freely, that means it not adjusting the lumbar support. If that's the case, that may be the cause of the clicking/slight-movement of the seat.
