1. Inspection:
* Remove the seat: This is the easiest way to properly inspect the mechanism. You'll need to remove the seatbelt bolts (usually two), and disconnect any electrical connectors (if heated seats are present). Consult your owner's manual for precise locations and procedures.
* Examine the Tracks: Look for bent, broken, or severely rusted metal on the tracks themselves. These are usually located underneath the seat and run along the floor.
* Check the Rollers: These are usually small plastic or metal wheels that allow the seat to slide. Look for cracked, broken, or severely worn rollers. They might be jammed with dirt or debris.
* Inspect the Seat Mounting Bolts: Make sure all bolts are tight. Loose bolts can allow the seat to shift.
2. Repair Options (depending on the problem):
* Clean the Tracks and Rollers: If the problem is dirt and debris, thoroughly clean the tracks and rollers. Use a wire brush, degreaser, and compressed air to remove any buildup. Lubricate the tracks and rollers with a silicone-based lubricant (NOT WD-40; it's a solvent and will evaporate, leaving things drier than before).
* Replace Worn Rollers: If the rollers are cracked, broken, or excessively worn, you'll need to replace them. These are sometimes available at auto parts stores, but it might require some searching (providing the model year and seat type will help). You might need to carefully pry the old rollers out and then press or snap the new ones in.
* Repair or Replace Tracks: If the tracks are bent, broken, or severely rusted, you'll likely need to repair or replace them. Repairing bent metal might be possible with careful bending (be cautious not to break it further!), but replacement is usually a better long-term solution. This is more involved and might require welding or specialized tools.
* Tighten Mounting Bolts: If bolts are loose, tighten them to the manufacturer's specifications.
3. Reassembly:
Once you've addressed the problem, carefully re-install the seat, ensuring all bolts are tightened securely and electrical connectors are reconnected properly.
Important Considerations:
* Safety First: Always disconnect the battery's negative terminal before working on any electrical connections.
* Professional Help: If you're uncomfortable working on your car's interior, or if the damage is extensive, it's best to take your Sebring to a qualified mechanic or upholstery shop. Replacing the tracks can be a significant undertaking.
* Parts Sourcing: Finding replacement parts for a 1999 car can be challenging. Online auto parts stores, junkyards, and Chrysler dealerships are your best bets. Providing your VIN number will help ensure you get the correct parts.
Remember to consult your owner's manual or a repair manual specific to your 1999 Chrysler Sebring JXI for detailed diagrams and instructions. Pictures you take during disassembly will also be invaluable during reassembly.
