SOURCE: 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.

Where is the location of the power seat circuit breaker on a 2001 s10 blazer lt?


I think that more than likely wher eit draws the power in the fuse box the circuit feed to the fuse is burnt out ,this is often a strip on the back of the fuse box that runs across the frrd to the fuses so check for a feed in the fuse box on the fuse for the power seat

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.

2000 Gmc jimmy power lumbar works but seat does not, can't find the exact fuse for seat?


IF THE LUMBAR IS WORKING, THE POWER IS THERE . IF EVERYTHING IS PLUGGED IN UNDER THE SEAT, THE SEAT MOTOR MAY BE FAULTY

Power seat controls are not working


First of all, check under the seat where there should be a cluster of wires. Sometimes if the power seat is used alot by sliding back and forth, without this cluster of wires being secured, occassionally a wire can get cut.
The runners on which the seats move are metal and cut wires easily. Secondly, the plug also located under the seat could have gotten wet or accidently came unplugged from someones feet in the back or objects and debris.
Another possibilty that will keep power seats from working is the power seat motor. In most cases, this small electrical motor is located directly under the power seat control panel or very nearby
Also you could check the fuses in the fuse box, located directly above the driver's left foot area. Power seats are usually on thier own circuit which means if the power seat fuse is blown, that is the only malfunction that will be noticed, versus other circuit which have many power items on one circuit. For example dash light, clock, and temp lights don't work, one fuse will fix the problem. Power seats operate on one fuse circuit which could have one or more fuses depending on the options of your seats. E.g. heated or not, lumbar, etc.

The Lumbar support adjustment fails


I wonder if you dont have a bad switch. I had a similar problem on my car except that it was the heated seats that would not engage... the power seat buttons all worked just fine. I changed the switch and it fixed the problem...
