DYNAMAXReplace or investigate blades that are damaged, aged or still streak after cleaning. Calendar intervals are reminders, not safety guarantees; fit, locking and wet-glass testing are essential.
Separate dirt from damage
Clean glass and blades as permitted, then test wet. Splits, missing sections, hardening, skipping and unwiped areas need action. If new blades skip, check glass films, connectors, frames and arms; oil or tire dressing is not a repair.

Describe where and when the problem occurs: one persistent line, a film on every sweep or skipping only on dry glass suggests different causes. Remove grit, sap and wash residue using products approved for glass and rubber, without aggressively sanding blades. Cleaning does not restore cracked or hardened rubber. Persistent obstruction in the main viewing area needs replacement or inspection before any calendar deadline.

Matching length may not fit
| Item | Decision |
|---|---|
| Vehicle and position | Check year, front/rear and side. |
| Connector | Match original attachment and adapter; do not force it. |
| Refill or assembly | Use a refill only if supported and the frame is sound. |

Provide vehicle year, front/rear position and connector photographs, then use fitment information for an assembly or insert. Left/right lengths and rear attachments may differ; a longer blade may interfere with another blade or trim. Fit adapters by product and vehicle instructions, not by whether they can be forced in. Damaged frames, worn retainers or unsupported insert designs favor a properly matched assembly over cut-down or mixed components.

Protect glass before removal
Park, turn wipers off and use the manual’s service position rather than forcing a concealed arm upward. Protect glass with a towel and hold the arm throughout removal and installation. Confirm locking with a gentle retention test; do not let a bare arm snap back or lift beyond its intended angle.

In the cited Model 3 manual, Park and switch the wipers off, then use Controls, Service and Wiper Service Mode. Lift only enough to access the blade. Its arms do not lock upright, so hold them and protect the glass with a towel. Release the tab, remove the blade and slide the aligned replacement into its lock. Follow the click with a gentle push-pull retention check. This is a version-specific example, not a procedure for every connector or arm.

Test the complete sweep
Return to normal position, spray washer fluid and check interference, loose fit, noise and streaks in the main field of vision. Maintain jets and fluid and avoid wiping dry grit. Time varies by attachment and vehicle, so five minutes is not guaranteed; not every insert can be cut down with reused steel strips.

Lower the arms, remove tools and towels, exit service mode and wet the glass. Check full travel of both blades, connector movement, interference and unwiped viewing areas. Perform acceptance while parked rather than driving with poor visibility. If washers fail, inspect level and blockage instead of dry-testing new rubber. Stop for interference or looseness and recheck fit.

When to use a workshop
Stop forced installation and repeated operation for insecure connectors, bent arms, failed motors or damaged glass. Pull over safely when rain obscures vision; coatings, rain sensors and driver assistance do not replace clear visibility.

Troubleshoot new-blade problems through cleaning, fitment, retention and arm condition. Remove films, verify part and attachment, then have a workshop assess the arm, mounting and drive. Rain sensing controls activation but cannot repair rubber or restore contact; coatings do not replace damaged blades. Existing scratches or cracks require assessment rather than attributing every noise to the new part.

Record installation date, side-specific parts and post-cleaning test results, and inspect before seasonal changes or long trips. Bosch recommends annual replacement or earlier for poor performance; this Tesla manual also provides an annual reminder. These guides do not guarantee a year of safe life for every blade. Compare fit, included adapters, installation and acceptance work when evaluating cost.

Frequently asked questions
Q1. Must I replace every six months?
Follow vehicle/product guidance and act early on poor performance; one interval is not universal.
Q2. Can I replace only the insert?
Only with compatible design, profile and retention; replace the assembly for damaged frames or uncertain fit.
Q3. Why does a new blade streak?
Clean glass, then inspect fitting, arm and washers; do not abrade or oil rubber.
