The windshield wiper switch on my 2001 lumina needs to be replaced and I am thinking of doing it myself. How hard is it to do this? Is it true that I would need to take the steering wheel off?

The glass shop probably put the arms back on in the wrong position. You can remove the arm and reset them at a different clock position and see if that helps.

You may look or feel the back side of the steering wheel, looking for 2 screws that hold the airbag to the wheel, these will be internal torq type screws (star) you may have to rotate the steering wheel 90 degrees to access the screws. You should first disable the airbag, by removing the airbag fuse, and or by disconnecting a yellow connector located near the base of the steering column. under the knee bolster.(panel below column). Once the retaining screws are removed, lift bag and disconnect the 2 connector to the airbag, the ground for the horn, and the horn contact wire, which requires you to push down and twist counter clockwise, damage to the horn contact ring will occur if you try and just pull connector from the ring. Now you can remove the steering wheel, may require a puller, and the you will have access to the turn signal switch.
