1. Safety First:
* Disconnect the battery: This is crucial to prevent electrical shock. Disconnect the negative (-) terminal first.
* Work in a well-lit area: You'll need good visibility to see the small components.
* Take pictures: Before you disassemble anything, take plenty of pictures to help you remember how everything goes back together.
2. Diagnosing the Problem:
* Check the obvious: Make sure the seat is properly plugged into the power supply. A loose connection can cause intermittent function. Inspect the wires for any visible damage (cuts, frays, corrosion).
* Test the power: With the battery disconnected, use a multimeter (if you have one) to check for power at the connector to the seat motor. This helps determine if the problem is with the motor itself or the wiring.
* Listen carefully: As you try to operate the seat, listen for any unusual noises (grinding, clicking, etc.). This can indicate a mechanical problem within the seat mechanism.
3. Potential Solutions (requiring disassembly):
* Clean the connectors: Corrosion on the electrical connectors is a common culprit. Disconnect the connectors and carefully clean them with contact cleaner. Make sure they are fully seated when reconnecting.
* Check the wiring harness: Carefully inspect the wiring harness running to the seat motor. Look for any breaks, pinched wires, or damaged insulation.
* Replace the seat motor: If the motor itself is faulty, it will need to be replaced. This is often the most likely cause of the intermittent functionality. You'll likely need to purchase a replacement motor specific to your year and model of Town & Country.
* Lubricate the mechanism: Sometimes, the seat's internal gears and tracks can become stiff or sticky. Applying a suitable lubricant (like white lithium grease) to moving parts can help, but this is less likely to be the sole cause of the problem you're describing.
* Inspect the switch: Though less likely given your description, the power seat switch itself could be faulty.
4. Disassembly (This is complex and requires patience):
* Remove the seat: This usually involves removing bolts beneath the seat and possibly disconnecting some electrical connectors. Consult a repair manual specific to your year and model Town & Country for detailed instructions. This is the most difficult step.
* Access the motor and mechanism: Once the seat is out, you will likely need to carefully remove parts of the seat's interior to get access to the motor and internal components. Again, a repair manual is essential here.
5. Repair Manual:
You absolutely need a repair manual specific to your year and model Chrysler Town & Country. These manuals provide detailed diagrams and instructions for disassembling and reassembling the seat. You can find them online (for purchase) or at auto parts stores.
Important Note: If you are not comfortable with automotive repair, it's best to take your vehicle to a qualified mechanic. Improper disassembly or repair can cause further damage. The complexity of this repair makes it a project best left to someone experienced unless you have significant automotive repair experience.
