1. Door Won't Open or Close:
* Check the tracks: The most common problem is debris, rust, or damage to the sliding door's tracks. Thoroughly clean the tracks with a wire brush, degreaser, and then lubricate them with silicone spray or white lithium grease. Pay close attention to the rollers and the track itself. Bent or damaged tracks will need repair or replacement.
* Inspect the rollers: The rollers at the bottom and top of the door can wear out, seize, or become misaligned. Inspect them for damage or excessive wear. Replacement rollers are readily available from auto parts stores.
* Check the door latch mechanism: There might be a problem with the latch itself, the linkage, or the actuator (if it's electrically operated – some models had power sliding doors). Lubricate moving parts, and try to manually operate the latch to see if it's the problem. If it's broken, you'll need to replace the latch mechanism.
* Check the cables: Some Aerostars use cables to help control door movement. These cables can stretch, break, or come unattached. Inspection and possibly replacement might be needed.
* Power sliding door issues (if applicable): Check the motor, wiring, and fuses if your door is power operated. A malfunctioning motor or faulty wiring could prevent the door from moving.
2. Door Doesn't Stay Closed:
* Check the latch mechanism: The latch might not be engaging properly. Check its alignment and operation.
* Inspect the striker plate: The striker plate (the metal plate the latch engages with) might be bent, damaged, or loose. Tighten or replace as needed.
* Check the door seals: Worn or damaged door seals can allow the door to sag and prevent the latch from fully engaging. Replace the seals if needed.
3. Door is Difficult to Open or Close:
* Clean and lubricate the tracks and rollers: As mentioned above, this is a common cause of difficulty in operation.
* Check for binding: Something might be obstructing the door's movement in the tracks. Remove any obstructions.
4. Door Makes Noise:
* Clean and lubricate the tracks and rollers: Squeaking or grinding noises often indicate a need for lubrication.
* Check for loose parts: Tighten any loose screws or bolts associated with the door and its mechanism.
Repairing the Door:
* DIY Repair: If you're mechanically inclined, many of these repairs can be done with basic tools and readily available parts. Consult a repair manual specific to your 1996 Ford Aerostar for detailed instructions and diagrams.
* Professional Repair: If the problem is complex or you're not comfortable working on your vehicle, it's best to take it to a qualified mechanic.
Before you start:
* Safety First: Disconnect the battery's negative terminal before working on any electrical components.
* Repair Manual: A repair manual specific to your 1996 Ford Aerostar is invaluable. It will provide detailed diagrams, specifications, and troubleshooting guides.
Remember to always consult a repair manual for detailed instructions and diagrams relevant to your specific vehicle. Improper repairs can lead to further damage or safety hazards.
