The motor I got works as intended. It was a reman motor from Cardone and had the part number for the motor I pulled off the car cross listed 3431606. Its definently a newer design so I am not sending my OE one back in hopes that I might be able to get it working right in the future.
If I understand the 2 speed wipers right, the conceal motor needs the conceal switch and linkage cam or it wont park. It will run in reverse during parking, and up to 359 degrees to get to the right position before it opens the motor contacts. The non-conceal wipers park in the same direction as operation and open the park contact every revolution.
Double check that you have the the linkage cam and switch too, or it wont make any difference. (I forgot the cam at first and it doesnt park or function correctly without it.)
