2000 Ford Windstar wiper issue. Worked with new motor with car not running but key on to work wipers. Worked on intermittent, hi and low. When turned ignition on and drove the next day, used wipers and made an awful grinding noise and locked up on middle of window. Replaced wiper motor 4 or 5 times already.

Hey Derek , here is how the wipers park position is suppose to work !
Windshield wiper motor park operation is controlled by the body control module (BCM) using an input from the park switch within the wiper motor assembly. The BCM monitors the windshield wiper motor park switch circuit to determine if the windshield wiper blades are at the bottom of the glass. The circuit will be pulled to ground by the wiper motor park switch while the windshield wiper motor is operating. When the wiper switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the BCM will continue to operate the motor until the wipers reach the park position. If the ignition is turned OFF while the wipers are in mid-cycle, the wipers will stop immediately where they are. The BCM will park the wipers the next time the ignition is turned ON.
The wipers will not park when they are commanded ON and OFF with a scan tool. The BCM will park the wipers the next time the wiper switch is turned ON and OFF.
The BCM provides stall protection for the wiper motor by monitoring the park switch. If the park switch does not transition for 3 seconds while the wipers are operating, the BCM will assume that the wiper motor is stalled, and will de-energize the wiper relay until the wiper switch is cycled OFF and ON again.
Check for a voltage signal on the yellow wire at the wiper motor assembly , this is signal to the BCM ! If there is no signal you need to replace the windshield wiper motor assembly ? If there is a signal need to have Tech 2 scan tool hooked up to see if The BCM is the problem ! Relay #39 an #40 are the high an low wiper relays in the under hood fuse block ! Do you have a volt meter ,do you know how to do electrical testing ?
Try to shut off the key when wipers are at the bottom or the park position. Then unplug the wiper motor wire for a day or so after driving car. With the car off plug them back in fi they still run all the time you need to replace the wiper motor.
The wiper motor is defective and needs to be replaced. Inside the wiper motor is a "Park Switch". When you turn the wipers off, the park switch sends a signal to shut the wipers off. If the park switch fails to operate then the wipers will continue to run, unless the ignition key is turned off. You will also need to inspect and test the charging system. Where you had no issue before the rain, you may only need to charge the battery. After the battery is charged it should be load tested, to be sure that it is fine. Also test the alternator and make sure that it is charging correctly (@14volts). If you need more information please write back. Good luck.
From your description it sounds like you need a new rear wiper motor. If I understand your description correctly. When you active the rear wipers, they work but when you press the same button, to turn them off. The wipers still continue to move. The wipers will turn off if you turn off the ignition key (when the wiper blade is in the parked position). and when you restart the van the rear wiper still stays off until you press and active the rear wipers. If I understood you correctly then I will suggest that you take a closer look at the rear wiper motor. If you have any other questions, please write back. I would like to hear from you and the progress you have made, good luck.
Those are accessory functions working off the ignition switch when in accessory position or run position of the key. Were you to check if the wiper and radio fuse had power to them in the run or accessory position as they should, likely they would not. Power from the switch goes to the fuse panel, powering the fuses and circuits that only work with key in on or acc., either a direct wire to the fuse panel or sometimes, fuses get power from an accessory relay that sends power to fuses, but relay has to get a signal from a good working switch before it powers the fuses. What I'm trying to say, is the bad switch is probably the reason you have no wipers, radio, or mirrors.
Sounds like a possible ignition switch or ignition actuator problem to me. I would recommend getting it checked by a professional so you do not end up replacing MORE parts that do not fix the problem.
Eg wipers work while ignition switched to 'accessories' but stop when key turned to 'start'
I had this issue and took me ages and ages of wire tracing and probing. Your fuse box should have the wiper/windows accessories fuses. If you probe them and they aren't showing voltage, check wiring harness, check wiper motor voltage. My ignition barrel was the fault of all this, everything worked when switched to "accessories", but while the engine was running, the accessories turned off. The bottom of the ignition barrel pushed out, as the factory stopper groove bent out. All I did was cold chisel a dent back into the case. BAM fixed my windows/starting/wipers all in one go.
it would appear that in the process of the engine mount breaking and replacing it that one of the wire harnesses was damaged and may have some wires that need to be insulated.
