Why do I have to turn my car off to get my windshield wipers to turn o

Hi @dakotahayn73578

Seems like it may be a faulty wiper motor "park" switch or electronic control board. (The park switch is open when the wipers are in the home position)

As both are located in the wiper motor assembly it's probably easier to just replace it.

Unfortunately I cannot find a video or guide that shows how to do this for your specific model but generally it's the same for most as you first have to remove the wiper blades and then the cowl panel between the hood and the windscreen to access the wiper motor.

Search online for 1992 cutlass ciera wiper motor to find suppliers that suit you best (examples only)
