Tools You'll Need:
* Wiper arm puller: This is highly recommended and prevents damage to the wiper arm and the wiper spindle. You can usually find them at auto parts stores.
* Socket wrench (possibly): Some wiper arms have a nut underneath a decorative cap.
* Penetrating oil (like PB Blaster): This helps loosen things up if they're stuck.
* Shop rags or paper towels: To clean up any fluids.
* Gloves (optional): To protect your hands.
Procedure:
1. Disconnect the battery: This is a safety precaution to prevent accidental short circuits.
2. Prepare the wiper arms: Spray penetrating oil around the base of each wiper arm where it attaches to the wiper spindle. Let it sit for 10-15 minutes to penetrate any rust or corrosion.
3. Locate the wiper arm nut (if applicable): Some Sunfires might have a small nut under a decorative cap at the base of the wiper arm. If so, carefully remove the cap (often just pops off) and use the appropriate socket wrench to remove the nut. *Be careful not to lose the nut.*
4. Use the wiper arm puller: This is the safest way to remove the wiper arm. Position the puller claws correctly on the wiper arm and tighten the center bolt. The puller will gently pull the arm off the spindle. Do not attempt to pry it off with screwdrivers or other tools!
5. Manual removal (if no puller): If you absolutely *must* remove the arm without a puller, try this as a last resort: Grab the wiper arm firmly and pull while twisting it slightly back and forth. This is risky and likely to damage the arm or spindle.
6. Repeat: Repeat steps 3-5 for the other wiper arm.
7. Clean the spindle: Once the arms are off, clean any dirt, rust, or corrosion from the wiper spindles.
Important Considerations:
* Spindle damage: If the wiper arm is extremely difficult to remove, it's possible the spindle is damaged or seized. In this case, you might need professional help or replacement of the entire wiper mechanism.
* Wiper arm replacement: If the wiper arms are damaged during removal, you'll need replacements. Make sure you get the correct ones for your 1996 Pontiac Sunfire.
