1. Interior Access: You'll almost certainly need to access the handle mechanism from the *inside* of the van. This usually involves removing the interior door panel.
* Remove the Interior Panel: This typically involves unscrewing screws located around the perimeter of the panel (look for them near the armrest, at the bottom edge, and possibly along the top). There might also be plastic clips holding the panel in place – these can be carefully pried loose with a plastic trim tool or flat-head screwdriver covered with tape to prevent scratching. Be gentle to avoid breaking the clips. Consult a repair manual for your specific year and model if you're unsure where these fasteners are.
2. Locate the Handle Mechanism: Once the interior panel is removed, you'll see the mechanism connecting the inside and outside handles. The exterior handle is likely attached to a rod or linkage that connects to the latching mechanism.
3. Disconnect the Linkage: Carefully disconnect the linkage rod(s) connecting the inside and outside handles. This might involve removing a clip, a nut, or a small bolt. Take pictures before disconnecting anything to help you remember how it goes back together.
4. Remove the Exterior Handle: Now you can access the exterior handle itself. There might be screws holding it in place from the inside, or it might simply pull off once the linkage is disconnected. Again, carefully examine the mechanism; some handles are held on by retaining clips, while others use screws.
5. Reassembly: Once the handle is off, reverse the steps to reassemble. Make sure the linkage is properly reconnected and the interior panel is securely fastened.
Important Considerations:
* Repair Manual: A repair manual specific to your 1988 Chevy Vandura 20 is your best resource. It will have diagrams and detailed instructions specific to your vehicle. You can often find these online (eBay, Amazon) or at auto parts stores.
* Photos: Take plenty of photos as you disassemble the door panel and handle mechanism. This will be invaluable when you reassemble everything.
* Patience: Be patient and methodical. Rushing can lead to broken parts or damage to the door panel.
* Tools: You'll likely need a screwdriver (Phillips and possibly flathead), a plastic trim tool, and possibly a small wrench or pliers.
If you're not comfortable working on your vehicle yourself, it's best to take it to a qualified mechanic. Replacing a sliding door handle is usually a relatively inexpensive repair job for a professional.
