Step-by-Step Instructions
Follow these steps carefully
1
Service position (if needed)
The 2021–2024 Model S (refresh) requires wiper service mode first: on the touchscreen go to Controls > Service > Wiper Service Mode, which parks the arms upright. Don't force the arms up by hand — they tuck under the hood edge.
🔧 Mechanic's note — Tom Becker
I've found that if the arms won't lift, don't pull harder — check the touchscreen first. Nine times out of ten on the refresh Model S, service mode just wasn't engaged. Forcing them risks a $300 arm and a scratched cowl in one move.
2
Lift the wiper arm
With service mode engaged, lift one wiper arm off the glass until it stays up and slide a folded towel underneath. Never let a bare spring-loaded arm snap onto the windshield. Work one side at a time.
3
Release the old blade
The Model S uses a pinch-tab (16mm top-button) connector: squeeze the tabs and slide the blade off the arm. Note the orientation as it comes off. Pull straight along the arm — never twist sideways, which can bend the arm.
4
Match the new blade
The 2021–2024 Model S takes a 26-inch driver blade and a 20-inch passenger blade with the pinch-tab connector. Confirm the new blades have the pinch-tab adapter attached (many ship with several), and compare each against the old blade to verify length.
5
Install until it clicks
Slide the new blade onto the arm until the tabs click, then tug gently to confirm it locks — 26-inch driver side, 20-inch passenger side. Each blade should lie flat with the rubber edge facing the glass as the old blade did.
6
Lower and repeat
Lower each arm gently onto the glass, repeat on the other side, then turn Wiper Service Mode off on the touchscreen so the arms park normally. Top off the washer fluid and run a wash cycle.
All Done!
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
⚠️ Common Mistakes to Avoid
- • Forgetting to activate Wiper Service Mode before attempting to replace the blades.
- • Using incorrect blade sizes or connectors, leading to improper fit.
- • Lifting the wiper arm beyond its intended position, potentially causing damage.
