How do you replace the windshield washer reservoir in a 2000 Bonneville?

You'll have to remove the right front wheel house extension to get at it. Remove the hose, electrical connections, and 3 nuts.

Guessing I would have to jack stand the car, pull R Wheel off and then get to the inner wheel well?? Does Pontiac use plastic pins to mount the inner wheel well cover or screws? I have not attempted to even look at this yet as I am constantly shoveling snow. Spokane 63+ inches so far this month!

You could try turning the wheel all the way to the left to get at it, but it would probably be easier with the wheel off. Yes,, plastic pins are used.
