I bought this wiper kit. https://www.ebay.com/itm/1953-56-F1...e=STRK:MEBIDX:IT&_trksid=p2060353.m2749.l2649 It actually isn't too bad in terms of quality for China made stuff. But the switch is a piece of crap and weighs about 3 oz. Plus it does not match the other switches that I have. So I contacted my switch guy and he sent me the options. One has dynamic parking and one does not. I called the manufacturer of the wiper kit and they didn't know what that meant. They said their motor is a "GM style". It does go back to a park position when the power is turned off. Is that dynamic parking? I just don't want to ruin the motor by getting the wrong switch. Here is a link t the switches. I need a 4 blade, no washer. Those are on page 2 of the link. https://www.elecdirect.com/media/specsheets/CHe1.pdf I appreciate any help.
