Oh YEAH ! Squeeze the tabs on either side of the wiper, and rotate to remove
from the bottom towards the hood, and away.
The regular attachment we are used to are available at the "National" Auto Parts
Stores, like auto zone,o'reileys,advance auto parts, etc. Ours are NOT like that.
So try to take one in with you and ask it it will fit your car, Trico, Bosch, etc.
Ours are different.
Also both wipers are "NOT" the same size, one is larger.
You "HAVE" to buy the whole wiper, NO refills are available, and expensive,
but they last, and last. they are Great.
Good Luck, and Have Fun.
For my 06 STS wiper blade I went to NAPA auto parts. Picked up Bosch, They called out 21" for the pass. & 24" on the driver side. Other brands spec 22" on the driver side. The Bosch cover more area and did a great job this pass winter. Part # are driver side 4842, pass side 4840. Paid about $ 26. for the set. Danny
