Winshield wiper pump/motor

[blarge]

I believe I need to replace wiper motor and /or pump - any advise on accessing this - resevoir is under front left?

The pump is mounted on the bottom of the reservoir on the outside. It's not hard to remove. I brought the front pump from GM for around $54., when I replaced the rear pump I went to AutoZone and paid $15 for the same pump.
