Installation Guide

Wiper Blade Installation Guide

This guide applies to Heritagedeni windshield wiper products and is intended to help customers complete the standard installation process. Installation can typically be completed in approximately 10 minutes without professional tools.

Please confirm vehicle compatibility before installation.

1. Before You Begin

Wiper blade sizes and connector types vary depending on vehicle make, model, year, and configuration. Please verify compatibility before installation.

Recommended Ways to Confirm Fitment:

Check your vehicle owner’s manual
Measure the length of the existing wiper blades (in inches)
Use a vehicle fitment lookup tool

Recommended Replacement Interval:

Wiper blades should generally be inspected or replaced every 6 months. Replacement frequency may vary depending on climate and driving conditions.

2. Types of Wiper Blades

Different wiper blade styles have different structural designs:

Type	Description	Common Applications
Conventional	Metal frame structure	Older vehicles
Beam	Frameless flexible design	Most modern vehicles
Hybrid	Protective outer shell design	Mixed weather conditions

3. Installation Steps

Step 1: Prepare the Vehicle

Turn the ignition to accessory mode (ACC)
Activate the wipers briefly and stop them midway on the windshield
Place a towel or soft cloth on the windshield beneath the wiper arms
Carefully lift the wiper arms away from the glass surface

⚠️ Caution: Avoid allowing the bare wiper arm to snap back onto the windshield, as this may cause damage.

Step 2: Remove the Old Wiper Blade

J-Hook / U-Hook Arms (Most Common)

Rotate the wiper blade to a vertical position
Locate the release tab or locking mechanism
Press the release tab
Slide the blade downward and remove it from the hook

Other Connector Types

Some vehicles may use side-pin, top-lock, or push-button connectors. Press the release mechanism and slide the blade out carefully.

💡 Tip: Replace one blade at a time to use the opposite side as a reference if needed.

Step 3: Install the New Wiper Blade

⚠️ Before installation, remove any protective plastic cover or shipping strip from the rubber blade.

Installation steps:

Align the connector with the wiper arm
Slide the blade into position
Push until the locking mechanism engages (a soft “click” may be heard)
Gently pull the blade to confirm it is securely attached
Carefully lower the wiper arm back onto the windshield

Common Connector Types

J/U Hook: Slide into the hook and rotate into place
Pin-Type: Align with the pin and press into position
Push-Button: Press the release tab while installing

Step 4: Repeat on the Other Side

Repeat the same process for the passenger-side wiper blade. If the vehicle is equipped with a rear wiper, a similar installation method may apply.

Step 5: Test the Wiper Blades

After installation:

Spray windshield washer fluid onto the glass
Run the wipers through several cycles
Confirm that:
- The blades move smoothly
- Wiping performance is even
- No abnormal noise or skipping occurs
- The blades do not contact the windshield edges

If any issue occurs, recheck the installation and locking position.

4. Common Issues and Precautions

Issue	Possible Cause	Recommended Solution
Poor wiping performance	Protective strip not removed	Remove protective cover
Blade becomes loose	Lock not fully engaged	Reinstall and confirm lock
Uneven wiping	Incorrect installation angle	Recheck orientation
Windshield damage risk	Wiper arm released suddenly	Always use a towel or soft cloth
