Turn ON your wipers then turn off your Mercedes-Benz GLK350 when the wipers are at their mid-way point on your windshield
With your wipers stopped midway on your windshield it should be easy to lift your wipers up and away from your windshield.
Your old wipers should stick out, away, from your windshield. Now allowing for easy access during the rest of the changing process.
Be sure to take note of which new blade length goes on which side.
Measure or just compare old blade length to the new Trico® wiper blades.
Then place the new blades on the correct side.
Your 2015 Mercedes-Benz GLK350 has a side pin attachment for the windshield wipers. Rotate the blade away from the tab. Then slide it off the pin.
Different wiper manufacturers use different style attachments for the side pin.
1. Push the small adapter lever toward the center of the blade.
2. While doing step 1, lift the factory installed adaptor off of the blade and discard it.
3. Find adaptor "BC" and press it in to the center of the blade.
The two nubs inside of the adapter lock onto the area on the blade marked "X"
4. Hold the blade at 90o angle to the end of the wiper arm and push it all the way on to the arm pin.
5. Rotate the blade until the tab on the top of the arm straddles the top of the blade.
6. The wiper blade will lock onto the arm where indicated.
Double check that wiper blades and adapters are locked on to the wiper arms.
Remove any wiper blade plastic covers.
Carefully lower your new wipers down to your windshield. Discard old wipers and packaging material.
