Sometimes you need to bend the arm to put more pressure on the glass.

you should only have to pull the steering wheel and upper and lower housing on the column,

Press on the spring lock, located where the wiper is attached to the arm. You may need a screwdriver for this. Once the lock is depressed, pull the wiper away from the arm. To replace, slide new wiper blade onto pin until it clicks.

This is a fairly simple job.
#1 Pull the wiper arm away from the vehicle.
#2 Turn the blade 90 degrees so that the blade and the arm make a 'capital T' shape.
#3 Pull the blade straight off of the arm.
#4 Install the new wiper blade so that it forms a ' T ' with the arm.
#5 Turn the blade back to the normal position in line with the arm.
#6 Ease the wiper arm and blade back against the windshield.
#7 You are done. Good luck
