1. Prepare the Area:
* Gather Tools: You'll likely need a trim removal tool (plastic pry tool is best to avoid scratching), a Phillips head screwdriver, and possibly a Torx screwdriver depending on the specific year and trim level.
* Clean the Area: Dust and debris can get in the way. Wipe down the area around the hatch panel.
2. Locate and Remove the Visible Fasteners:
* Upper Area: Start by inspecting the top edge of the hatch panel. There are usually plastic clips or screws holding it to the hatch itself. Use your trim tool to gently pry these clips loose. Work your way along the top. Be careful not to break the clips.
* Side Edges: Next, examine the side edges of the panel. Similar clips or screws will be found along these edges. Carefully remove them with your trim tool or screwdriver.
* Lower Edge (Warning Light): On many models, the lower edge often has the rear hatch warning light assembly. You *must* disconnect the wiring harness for this light before proceeding with removing the panel. This usually involves carefully releasing a connector.
3. Carefully Separate the Panel:
* Gentle Pressure: Once all the visible fasteners are removed, begin gently working the panel away from the hatch. Use your trim tool to gently pry along the edges. The panel is likely held in place by more clips. Work your way around the perimeter of the panel, releasing the remaining clips.
* Avoid Force: Avoid excessive force. If it's not coming loose easily, you likely missed a clip or screw. Carefully re-examine the edges.
4. Disconnect any remaining Wiring:
* Washer Fluid Nozzle (Possible): Depending on the model, the rear washer fluid nozzle might be attached to the inner panel. Gently disconnect this if present.
5. Remove the Panel Completely:
* Lower and Lift: Once all clips and wiring are disconnected, gently lower the panel away from the hatch.
Important Notes:
* Take Pictures: Before you start, take pictures of how the panel and clips are positioned. This will be invaluable during reassembly.
* Clip Replacement: Be prepared to replace broken clips. They are relatively inexpensive and available at most auto parts stores. Having replacements on hand is always a good idea.
* Year and Trim Variations: While the general process is similar, there might be slight variations depending on the specific year and trim level of your 1999 GMC Jimmy. Searching for a specific "1999 GMC Jimmy rear hatch panel removal" video on YouTube might help you visualize the process for your particular vehicle.
If you are uncomfortable performing this task yourself, taking your Jimmy to a qualified mechanic is always the safest option. They have the experience and tools to do the job quickly and safely, preventing any damage to your vehicle.
