1. Prepare:
* Gather your tools: You'll likely only need a flathead screwdriver or a wiper arm puller tool (recommended for easier and safer removal).
* Park and secure: Park your vehicle on a level surface and engage the parking brake. Turn off the ignition.
2. Locate the Wiper Arm Release:
* Inspect the wiper arm: Look closely at the connection point between the wiper arm and the wiper transmission spindle. There's usually a small tab, clip, or a small release button hidden under the wiper arm itself (often underneath a plastic cap or cover). This is the critical point to understand before proceeding. Some models might have a simple clip. Others require slightly different techniques.
3. Release the Wiper Arm:
* If there's a visible tab or clip: Carefully use a flathead screwdriver to gently pry this tab or clip to disengage the arm from the spindle. Use a smooth, controlled motion to avoid damaging the mechanism. If there's a small plastic cover remove that first to access the release.
* If there's a button or similar mechanism: Locate this button and depress or manipulate it while simultaneously attempting to lift the wiper arm.
* If there's nothing obvious and it seems to just "clamp on": This is where a wiper arm puller tool is strongly recommended. These tools provide leverage to safely release the arm without damaging anything. Improper removal by force can damage the wiper arm or the spindle.
4. Remove the Wiper Blade:
* Once the wiper arm is detached, the wiper blade itself should simply lift off. Some have a hook or a simple pressure connection. You should be able to slide it away from the arm or just pull it straight off.
5. Install the New Wiper Blade:
* Attach the new wiper blade by reversing the process you used to remove the old blade. Make sure it's securely attached.
6. Reattach the Wiper Arm:
* Align the wiper arm with the spindle and carefully press it down until it clicks into place. You should feel or hear a definite "click" indicating a secure connection.
Important Considerations:
* Consult your owner's manual: Your owner's manual should have specific instructions for your 1995 GMC Safari model. This is the best resource for detailed, model-specific instructions.
* Take pictures: Before you begin, take pictures of the wiper arm connection to help you remember how it goes back together.
* Gentle force: If you're having trouble, don't use excessive force. Stop and re-evaluate your approach.
If you're uncomfortable performing this task yourself, it's always best to take your vehicle to a qualified mechanic. They have the right tools and expertise to do the job safely and efficiently.
