Anybody know where I can find one for recessed park wipers? My switch turns on the wipers just fine but most of the time the only way I can get them to shut off is to shut off the car. They usually try to stop, then raise slightly, and this repeats, and repeats. Not being an electrical guru I thought it might be the switch. All I've been able to find for a 70 are for cars without concealed wipers. Thanks in advance.
