Drivers side seat will not adjust in the up and down position. When activated, it appears that solenoid is triggered, but seat will not raise or lower. Front and back adjustments are fine.

I had the same problem. It turned out that the previous owner(s) had let a lot of sticky trash accumulate under the seat. After the seat was removed and everything (seat tracks and floor) was given a good cleaning, the seat goes up and down just fine.

Seat height adjustment


Hi
There should be a set of levers on the right hand side (left hand if you are on the left). one of these will move the seat back and forth, one will raise and lower and one will move the seat back.
Some of these rise and fall levers are a "pump action style" where you push down to get the level or pull up.
Other type will raise the seat fully either up or down. Its on a cam.
I have had these seize before and have had to replace the mechanism.
Cheers
Roger

What could cause my drivers side power seat to stop moving forward and backward?


sounds like you might have a switch problem if the memory for seat position works ok. If you have a multimeter that checks for continuity then you could start there at the switch but you would also need a wiring diagram for the seats

Passenger seat won't lock in place


The adjusting lever for seat position is not locking into place. On the bottom of seat are runners on each side with holes in them that the adjusting lever tabs will lock in and hold seat in place. The seat slides on the runners if those tabs are raised. There is also a connecting wire or rod from the lever to the other side of seat so when lever is pulled up, tabs on both runners are raised for seat to slide. Something is keeping the tabs from locking into the holes on the runners in your car. Maybe the adjusting lever is broken somewhere, or the wire/rod came loose, or the lever is just dry and sticky and needs a shot of WD40 to loosen it up. If you can't see it and fix it with seat in place, then pull the seat back off for the repair. Good luck. Post back if my explanatiopn is not clear or you still need help.

I have a 2008 Chevrolet Silverado 1500, extended cab, automatic truck.......PROBLEM, the drivers side has a power seat, it will not move in any direction and the passenger side front and rear power windows...


How to diagnose this problem ? Viewing wiring diagrams to see what all is invovled in these electrical circuit's , check power supply's an ground connection's using a DMM - digital multimeter !
What type power seat's ? does it have memory ,heated an cooled etc ?
Power Seats System Description and Operation
There are 2 options of power seat systems available in full size trucks. The first is 6 way driver and passenger power seats without memory. The second is an 8-way driver seat plus 4-way lumbar with memory, heat and optional cool function. While the passenger has 8-way power seats with heat and optional cool function. For the driver memory seat operation, refer to Memory Seats Description and Operation. Power seats without memory are completely controlled through the power seat switch. Battery voltage is supplied to the power seat switch through the power seat circuit breaker. While the seat adjuster switches are in an inactive state the switch contacts are closed to the power seat switch ground circuit. When a power seat switch is pressed to an active state the switch contact is closed to the battery voltage supply circuit. Each seat adjuster motor is controlled by the power seat switch through 2 motor control circuits. 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.

If it has memory seat's there is a control module !
Battery voltage is supplied to the driver seat module through a 25 A circuit breaker. The driver 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.
Both right side windows have a seperate power supply from the left side window's ,has RT DOORS circuit breaker CB1 - 25amp. location left instrument panel fuse block . Circuit breaker's very rarely fail .Do the door lock's work on that side of the vehicle ? The windows won't work with their own switche's ?
The DDS controls the passenger window through a GMLAN message to the PDS. When a power window switch is activated in the up or down positions the PDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the PDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist, and during window motor operation the PDS continues to monitor the motor current to verify proper window motor operation. (Scan tool support is available for this system)
Check PDM fuse 4 15 amp ,this supply's B+ voltage to the DOORLOCK/WINDOW switch passenger side . Check for broken wires inside the flex boot from the body to the passenger door .

I have a 2004 Chevy Silverado. The heated seat on the drivers side does not work. When you push the button to turn it on, the lights come on briefly then turn off.


Would you say it stays on about 30 seconds and does the passenger side do the same thing? If possible retrieving the codes will narrow down the search for a correct solution.If the passenger side is ok we may be able to eliminate the passenger side as bring part of the problem.Please advise so will know which way to go with your solution.


Condition/Concern:
Driver and passenger heated seats inoperative or shut off in 30 seconds. There will be DTCs B2435, B2440, B3606 and/or B1825 set in the Drivers Seat Module. The adjustable pedal position sensor, seat recliner position sensor and both heat seat thermistors share the same 5 volt reference internal to the Drivers Seat Module. A fault in any of these components/circuits can make the heated seats inoperative or shut off in 30 seconds, as well as, the seat recliner and/or adjustment pedals may move in short increments when operated. A fault in heated seats, adjustable pedal or seat recliner will affect BOTH heated seats.
Note:: Even if the vehicle is not equipped with adjustable pedals DTC B3606 still may set.


To help isolate the area of concern use the Tech 2 or a comparable scanner and go to "Sensor Data" in the Drivers Seat Module. Monitor the following parameters for being out of range:
Recline Position- Normal range .39V-4.58V
Pedal Position (if equipped) - Normal range .39V-4.58V
Psgr. Seat Heat Sensor- Normal range 1V-4V
Drvr. Seat Heat Sensor- Normal range 1V-4V
If a parameter is found to be out of range inspect circuits for any opens, shorts to ground, or voltage. If none found replace the suspect component.

Please be aware of the following common areas of concern:
  1. The adjustable pedal position sensor internally shorted pulling the 5 volt reference low. Disconnect the adjustable pedal position sensor and see if the heated seats start working correctly, if so replace. Note Important:: The APP (Accelerator Pedal Position) sensor is NOT the adjustable pedal position sensor. Make sure the correct sensor, adjustable pedal position sensor, is disconnected.
  2. The seat recliner position sensor internally shorted pulling the 5 volt reference low. Disconnect the recliner position sensor and see if heated seats start working correctly, if so replace.
  3. An open in either heated seat thermistor circuits (signal or low reference). The most common is the passenger thermistor where it passes through seat connector C305 pin "L" or "K" or C399 pins "R" or "G".
  4. A chaff to ground on either heated seat thermistor signal circuits. The most common is circuit 5475 black/red or dark blue shorted to ground in the passenger seat near the buckle. Note Important:: The heated seat thermistors act differently to "OPENS and SHORTS" than the adjustable pedal position sensor and seat recliner position sensor. The adjustable pedals and seat recliner sensors can be disconnected for testing of the heated seats. Where as the heated seat thermistor circuit must be working correctly before EITHER heated seat will operate. Disconnecting one thermistor, which may have a concern will not allow the opposite heated seat to work correctly, BOTH side must be operational before EITHER heated seat will operate.
Clearing DTCs
If DTCs will not clear when using the Tech 2 or comaparable scanner after a repair has been made, try operating the device in which the repair was made. Example, if a repair was made to the passenger heated seat thermistor circuit, the DTCs may not clear unless the passenger heated seat is operated.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

How do you remove the headrest on a 1996 ford crown victoria?


Head Restraints Each front seat is equipped with dual-post design front seat back head restraint (611A08). The front seat back head restraint is installed as follows:
  • It travels on dual posts which have notches to engage a spring-loaded catch in the guide.
  • The front seat back spring assembly retains the front seat head rest guide rod sleeve (610A16).
  • The front seat back head restraint is adjustable from its normal position to a raised position of approximately 25 mm (1 inch).
  • Pull up on the front seat back head restraint to raise it. Pushing down will return it to its normal position.
----------------------------------------------------------------------------------------------

Removal
  1. Unscrew front seat head rest guide rod retainers (610A18).
  1. Pull up on front seat back head restraint (611A08). Compress foam in area of front seat head rest guide rod sleeves (610A16).
  1. Remove front seat back head restraint positioning springs. Pull front seat back head restraint up and out.
Installation
  1. Slide front seat head rest guide rod retainers onto front seat back head restraint posts.
  1. Compress foam in front seat head rest guide rod sleeve area. Install positioning springs on front seat head rest guide rod sleeves.
  1. Insert front seat back head restraint posts (notches on posts facing rearward) into front seat head rest guide rod sleeves and push down to engage positioning spring.
  1. Tighten front seat head rest guide rod retainers onto front seat head rest guide rod sleeves.
  1. NOTE: Front seat back head restraint must operate smoothly throughout its range of travel, must remain in any fixed position, and must not be freely removable from the seat back. If any of these conditions are not met, check for proper installation of positioning spring onto front seat head rest guide rod sleeve.

    Adjust front seat back head restraint by applying hand pressure, either up or down, to center area of front seat back head restraint.

Drivers side seat will not go up or down as designed.


You could remove the seat and check to see if there is anything jammed in the seat rails causing the seat not to adjust up or down. Remove the 4 Torx-40 bolts from the rails tilt the seat back and disconnect the connectors that are lined up under the bottom of the seat. MAKE SURE THE KEY IS OFF AND STAYS OFF. Check the rails, check the operation of the height adjust. If it still does not work then it most likely needs seat rails.
