How do you find and replace the windshield washer pump on the 2005 dodge magnum RT

The pump is located inside of the fluid holding tank itself. I would suggest checking the 30 amp (pink) fuse for the windshield washer pump before attempting to replace the pump. The fuse is located in engine compartment distribution block. Find the location of the 30 amp fuse by looking in your car's manual. If the fuse looks fine try swapping it out with an identical 30 amp fuse from the distribution block and trying the washers again. I believe there is one other 30 amp fuse (possibly for the headlights?) in that same location.

Replacement (if necessary) is no easy task as it would require removing quite a few parts of the front fascia of the vehicle including the front bumper and possibly passenger's side fender.
