On 97 crown victoria when i turn wipers off the go in the up position

Susan, inside the wiper motor is a parking peg which controls the position of wiper blades when off, It is possible the peg is damaged or broken. The wiper motor would have to be replaced in this case. You can find a used one at the auto wreckers, just make sure the plug is the same as yours, as they may be different from one year to another.Have a good Tech. check wipers, diagnose and estimate repair.
Check the attached links,instruction and guides, 1 st link gives procedure to change wiper motor. Good luck

2000 Ford Crown Victoria Windshield Wiper Issues Electrical

Use vinegar to unfreeze

Look under your hood on the driver's side of the engine compartment. There a black box located on the fender well with a cover on it. Under the cover, is a diagram showing the position of each relay fuse.

I suggest check position 2, 30A for Wiper Control Module, Windshield Wiper Motor...



Keep in mind that this and other important information could find in Ford Crown Victoria owners manual.

Jose.

check in Power Distribution Box, position 110, 30AMP (Cartridge fuse) for Wiper Module.

Follow the Dark Blue/White wire or Brown/White wire from the Multifunction Switch to the wiper module according to the schematic.
Also, one can trace the wires from the windshield wiper motor to the wiper module by peeling away the wiring loom and looking for a Yellow/Red wire that leads to the module.

I would look under your car and look for gas stain's, it's either going to be the filler or vent hose's or the o-ring where the fuel pump goes into the gas tank.

replace the wiper motor, the park position is broken, need to replace complete wiper motor.

Hmmmm... if you replaced the motor you must have cleaned the area housing the arm mechanism. I had the same problem and found the problem to be in the arm assembly box on the firewall. Under the hood, triangular shaped box with snap on top was full of dirt, leaves and pine needles... I removed all the **** & my wipers now park as they should!!
