On my 02 I discovered that there is a tab on the parking mechanism that was not engaging on a tab on the wiper motor bracket. I just had to bend it some to engage that part of the parking mechanism. Easiest way to figure out where it is missing is to have someone operate the wipers while you watch with all of the covers removed. Do not put any fingers or tools in there while operating it.
The parking switch inside of the wiper motor is defective. Replace the wiper motor.
: There is a pawl located in the wiper motor that tells the motor when to shut off and leave the wipers in the parked position. : if your wiper blades park in the vertical position, this pawl has broken off. : the motor more than likely needs replacing.
Windshield wiper motors have an internal switch that allows a wiper motor to stay running long enough to keep the wipers moving until they reach the "park" position. Once the wiper gets to the park position, the wiper motor is shut off. The internal switch often fails and either the motor will shut off immediately, wherever it is or it will keep running. It sure seems that you need a new wiper motor.
It is definitely a pin inside the wiper motor that is worn out. I just had mine replaced in my 02 Montana. The pin can be seen by removing the cover from the motor.
compressor contactor is bad. probably stuck in the closed position.
sounds like the park switch in the wiper motor. (needs new wiper motor)
the windsheild wiper motor clutch/windlatch is broken
Most wiper motors have a " park " position. When current stops going to the motor ( when you turn off the switch ) they are designed to go back to this "park" position. IF YOU HAVE CHECKED TO MAKE SURE THAT YOUR WIPER ARMS ARE NOT STRIPPED OR LOOSE WHERE THEY CONNECT AT THE COWL ( YOU SHOULD NOT BE ABLE TO MOVE THEM ACROSS THE WINDSHEILD WITH YOU HAND USING SLIGHT PRESSURE), then your motor is most likely defective. It is probably the Wiper control module, which controls the function of the wiper motor. It may also be the wiper motor, but if wiper function is otherwise normal it's probably the module. When I called a couple of dealers asking about this problem on my van, they said that it is likely the module.
Possibly bad wiper motor, bad park switch, or bad wiper switch. Electrical short also possible.
Either the park switch (usually within the windshield wiper motor) is bad, not letting the wiper park, or the intermittent wiper control is bad, not letting it shut off. Another possibility is a bad ground.
The wiper motor doesn't turn off until the wiper arm gets to the "park" location. If the wiper motor never detects park, the wipers will stay running.
replace that black box on the wiper motor or sometimes you have to replace the motor itself
