changing windshield washer motor in a 2004 grandprix
Usually, it's attached to the washer tank and generally, it's just a 2-wire connector and a hose to disconnect and give the pump a pull. I don't know your specific vehicle but it's a pretty simple job.
If it's like my 2000 model the washer fluid tank will have to come out. It's "conveniently" located in the fender, behind the battery. The washer pump presses into the bottom of the tank. It is sealed and held in place by a rubber grommet. You'll want to replace that as well. HTH. - Jim
