Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety from electrical shock.

Tools Required:

Socket set
Screwdriver set
Multimeter
OBD-II scanner

2. Inspect and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse for the power seat and memory seat functions using the diagram on the fuse box cover.
Remove the fuse and inspect it; replace it if blown.

3. Check Memory Seat Switches

Remove the switch panel by unscrewing and gently prying it off.
Inspect the switches for damage or debris.
Clean the contacts with electronic cleaner if dirty.
Reassemble the switch panel.

4. Test Seat Control Module

Locate the seat control module (typically under the driver's seat).
Disconnect the module and check for power and ground using a multimeter.
If power is absent, trace the wiring back to the fuse box and check for breaks.
If the module is faulty, replace it with a new unit.

5. Test and Replace Position Sensors

Remove the seat from the vehicle for easier access to the sensors.
Inspect the position sensors for wear or damage.
Use a multimeter to test the resistance of the sensors; replace if out of specification.
