Tools You'll Need:
* New wiper arms: Make sure you purchase the correct wiper arms for your 1995 Pontiac Bonneville.
* Flat-head screwdriver (possibly): Some wiper arms use a simple nut and bolt, others utilize a retaining clip. A flat-head screwdriver might be needed to release a clip.
* Wrench (possibly): Again, this depends on the type of attachment mechanism your wiper arms use. A small wrench might be necessary if there's a nut and bolt.
* Shop towels or rags: To protect your windshield.
* Penetrating oil (optional): If the wiper arms are particularly stubborn.
Steps:
1. Park your car and turn off the ignition. This is crucial for safety.
2. Locate the wiper arm nut or clip. The mechanism securing the wiper arm to the wiper transmission shaft is usually visible at the base of the wiper arm.
3. Protect your windshield: Place shop towels or rags around the base of the wiper arm to prevent scratching the windshield during the removal and installation process.
4. Remove the old wiper arms.
* Nut and Bolt: If you see a nut and bolt, use the appropriate wrench to loosen and remove the nut. Then, pull off the wiper arm.
* Retaining Clip: If there's a retaining clip, carefully use a flat-head screwdriver (or your fingers, if possible) to pry the clip open or release the locking mechanism. This often involves gently prying up on a small tab or lever. Consult a repair manual or image search for your specific model to better understand the clip.
5. Clean the wiper transmission shaft: Use a clean rag to remove any dirt or debris from the shaft. This will ensure a proper connection with the new wiper arms.
6. Install the new wiper arms. Align the new wiper arm with the wiper transmission shaft.
7. Secure the new wiper arms:
* Nut and Bolt: If it's a nut and bolt, hand-tighten the nut before fully tightening with the wrench. Avoid over-tightening, which could damage the shaft.
* Retaining Clip: If there's a retaining clip, carefully push the arm onto the shaft, making sure the clip engages properly and snaps shut.
8. Repeat for the other wiper arm. Follow the same steps for the passenger-side wiper arm.
9. Test the wipers. Turn on your ignition and test your wipers to ensure they are functioning correctly and wiping across the entire windshield.
Important Considerations:
* Consult a repair manual: A repair manual specific to your 1995 Pontiac Bonneville will provide diagrams and detailed instructions for removing and installing the wiper arms. This is highly recommended, especially if you're unsure about the type of fastening mechanism.
* Take pictures: Before you begin, take pictures of the wiper arm attachment to help you remember how it all goes back together.
* If stuck: If you encounter significant resistance, don't force it. Apply penetrating oil and allow it to sit for a while to loosen things up before attempting again. Excessive force can damage the wiper arm or the wiper motor.
Remember safety first. If you're uncomfortable performing this repair yourself, it's always best to take your car to a qualified mechanic.
