The 1979-1991 Crown Vic wiper motor is located on top of a large plastic housing at the top of the firewall. It's easy to locate this housing if you do any engine work, because it does its best to block access to the rearmost bolts on the driver's side valve cover - one reason why I pulled the entire wiper mechanism when I swapped the engine on my first "Panther" chassis station wagon (a 1987 Mercury Colony Park). The mechanical wiper mechanism is hidden under the housing to prevent it from mangling the copious supply of fuel-injection-related wires that pass through the area. Note that it's easiest if you remove both wiper arms before servicing the system, since they're just one more thing you have to swing around to get things to line up. The wiper motor itself is is held to the housing by three bolts that are easily accessible (either 3/8" or 10mm head, as I recall) - just pull it part-way out, pry the crank arm off of the mechanical linkage inside the housing, disconnect the two electrical plugs going to the motor, and it's off.

Why do the windshield-wipers in a 1985 Ford Crown Victoria don't turn off when you try to turn them off?

On a 98 Chrysler minivan why do the wipers stop anywhere on the windshield and not at the bottom?

There is a switch inside the wiper motor that identifies the home spot for the wipers. If you have intermittent wipers there is also a controller for that. Either can give you problems but more likely the wiper motor switch. The wiper motor switch usually is not a separate part (comes with wiper motor assy.) Oh yeah, 1 other thing, be sure the wiper arms are installed correctly on wiper motor.
