Take a look at your vehicle. Can you access the wipers easily? Are they hidden under the hood line? To make changing them easier, you may have to turn on the ignition, turn on the wipers, and then shut the ignition off when the wipers are at their highest point.
The method of installation depends on the style of wiper arm. The styles below cover most vehicles:
Side Lock Style

How you remove the side lock style of wiper will depend on what kind of wiper is currently on your vehicle. If it is an original equipment-style wiper, use a flat screwdriver, and press the spring lock down in the middle of the wiper, and slide the wiper off the arm.
If it is a universal style wiper with an adapter, removal will still vary between manufacturers, but generally, you will use a flat screwdriver to pry off the plastic adapter from the wiper arm pin.
Once the old wiper is off, compare it to the new wiper to ensure you’ve got the proper length.
Installing wipers on a side lock wiper arm will vary slightly between manufacturers. With Trico Exact Fit, and Bosch Micro Edge Excel, simply slide the new wiper over the pin, and push down until it locks in place. For most other designs, slide the wiper over the pin, and snap the locking adapter in place.
IMPORTANT – Always check that the new wiper blade cannot be easily pulled off!
Hook Style

The hook is the most common wiper arm style on modern cars, and also one of the easiest to work with.
To remove the wiper, simply push up on the tab under the wiper, and it will be unlocked from the hook. Slide it back to remove the hook from the adapter, turn the wiper blade up, and then slide the wiper blade forward off the arm.
Some manufacturers use a slightly different type of adapter for the hook style arm. You may need to use a screwdriver to pop a tab up in front of the hook. (This tab stops the wiper from sliding back off the wiper.)
Once the old wiper is off, compare it to the new wiper to ensure it is the proper length.
Slide the wiper arm through the wiper blade, place the arm into the adapter behind the hook, and slide it forward into the hook until you feel it lock in place.
IMPORTANT - Always check that the new wiper blade cannot be easily pulled off!
Bayonet Style

To remove the bayonet style wiper, lift the locking lever or tab, and pull the wiper off the arm. Remember to not let the wiper arm snap back against the windshield.
Once the old wiper is off, compare it to the new wiper to ensure they’re the same length.
To install new wipers, pull the tab back, slide onto the wiper arm until the tab locks in place.
With some bayonet-style wiper blades, you may need to install the adapter onto the wiper arm first, and then install the wiper blade onto the adapter.
IMPORTANT – Always check that the new wiper blade cannot be easily pulled off!
Two-Screw Bayonet Style

To remove the two-screw bayonet style wiper blade, simply undo the screws and slide the old wiper off. If the screws are rusted, or break, you’ll need to get new screws.
Once the old wiper is off, compare it to the new wiper to ensure the new one is the proper length.
To install the new wipers, attach any necessary adapters, line up the screw holes, and reinstall the screws.
IMPORTANT – Always check that the new wiper blade cannot be easily pulled off!
