Sounds like broken linkage maybe. I think... you need to pull the air vent intake grill underneath your windshield wipers blades to get to it.
I had the same thing on my 2000 Crown Vic PI and it was the motor.
your multi function switch is more and likely going bad
Wiper motors have an internal switch that keeps the wiper running until it gets to the "park" position. Sometimes the internal switch fails and the wipers keep running, never sensing the park position. When that happens, you'll need to replace the wiper motor.
You probably have a faulty multi-function(turn siganl) switch.
The wipers motor has a tendency to become filled with water and short out the internal computer board causing it to malfunction.
if you have not done anything to the wipers before this poblem occured you more and likly have a bad motor check all speeds if they all work you can be sure the switch is good
The 1992 Ford Crown Victoria has the most common U-Hook wiper blade arm attachments. You press a button or tab and pull the wiper blade out of the hook. See Hook Arm Attachment Videos below...its a very easy install.
the delay for wipers doesn't work properly
the wipier switch on the coulum is bad
You pick up the wiper blade as far as it will go WITHOUT forcing it-Look where IT connects 2 the piviot (OR) car-there is a very small lever @ the base-PULL it AWAY from the Piviot POINT (car) maybe 1/2 inch & let the wiper back toward the windshield-when it stops wich will be B 4 it touches the windshield - U will B able 2 POSITION the ARM whereEVER U want. If the wipers are not parking correctly, you may simply need to replace the wiper motor. The wipers park when the motor runs backwards after the main power is cut off, and sometimes the switch gets broken inside the unit.
The 1998 Ford Crown Victoria windshield wiper relay switch can be found on the firewall in the engine compartment. The windshield wiper relay switch will be on the passenger side of the firewall.
No. There is not a "fuse" for the wipers. There is, however, a "circuit breaker" located in the fuse box under the the driver's side of the dash. Part # D9AZ 14526C.
